MK2703SI - Low-Jitter PLL Audio Clock Synthesizer | Renesas
The Renesas Electronics MK2703SI is a low-cost, low-jitter PLL audio clock synthesizer designed to replace discrete oscillator and PLL circuits in set-top box and multimedia systems. The verified source material identifies it as an 8-SOIC device with a 0.154 inch, 3.90 mm package width. The available data does not provide a verified output-frequency list, input-frequency range, supply voltage, current consumption, pin mapping, or exact operating-temperature values, so those parameters remain design-review items. A PLL audio clock synthesizer is a clock-and-timing IC that uses a phase-locked loop to generate or distribute one or more timing signals with controlled frequency relationships. In the broader electronics hierarchy, it belongs to clock generation, frequency synthesis, PLL, timing IC, and digital signal-support categories. This makes the MK2703SI relevant where audio, multimedia, or embedded systems need a stable reference or derived clock instead of a collection of separate oscillators and divider logic. The manufacturer search results identify the MK2703 family as a PLL audio clock synthesizer and specifically describe the device as a low-cost, low-jitter, high-performance alternative to oscillator and PLL circuits. The SI ordering suffix is associated with an 8-SOIC package in the verified distributor result. Because the supplied web data does not expose the complete electrical specification table, designers should verify frequency generation modes, reference requirements, output drive, supply limits, decoupling, and signal integrity against the official Renesas MK2703 datasheet before layout release. The MK2703SI can be considered for set-top box clocking, multimedia-system timing, audio-clock generation, decoder reference clocks, and embedded multimedia platforms. In a typical implementation, the device would receive a reference signal and produce one or more derived clocks required by downstream processors, converters, or audio circuitry. The main design trade-offs are package footprint, supported output frequencies, jitter, reference quality, supply noise, and whether the required clock architecture matches the device's verified control interface. Use the official MK2703 datasheet as the controlling source for pin names, timing diagrams, electrical limits, recommended crystals or oscillators, and application examples. Do not infer a pinout from the 8-SOIC package alone. In particular, verify every unused or no-connect pin, the exposed thermal requirements, the required supply bypass capacitors, and the maximum operating frequency before substituting the part into an existing design. This page consolidates the verified distributor identity, package information, family description, datasheet links, sourcing context, and engineering caveats for MK2703SI. It also distinguishes confirmed facts from parameters that still require datasheet verification, helping engineers identify the correct next step without presenting unverified clock or electrical values as specifications.
MK2703SILF - 27MHz PLL Audio Clock Synthesizer | Renesas
The Renesas Electronics MK2703SILF is a PLL audio clock synthesizer operating from a 27 MHz crystal or clock input, with a supply range of 3.13 V to 5.5 V, in an 8-pin SOIC package measuring 3.90 mm wide. Designed to replace discrete oscillators and PLL circuits, it generates a buffered reference clock and a selectable audio clock for set-top box and multimedia systems. A PLL clock synthesizer is a clock-and-timing IC that multiplies or divides a stable input reference to produce one or more synchronized output frequencies. In the broader semiconductor hierarchy, the MK2703 belongs to the PLL multiplier/divider family, the clock generator and synthesizer class, and ultimately the clock-and-timing integrated-circuit category. Its low-cost integration reduces component count and simplifies clock-tree construction compared with separate crystal oscillators, dividers, and phase-locked-loop circuitry. The verified product information identifies the MK2703SILF as a 27 MHz single PLL clock synthesizer with an 8-pin SOIC surface-mount package. It accepts a 3.13 V to 5.5 V operating supply and provides a buffered reference output together with a selectable audio clock. These functions are useful when downstream converters, codecs, interface circuits, or digital signal processors require a derived clock that remains phase-related to the system reference. Technically, the device uses analog phase-locked-loop techniques to lock an internally controlled output to the external 27 MHz reference. Locking the synthesized clock to the same reference used by the rest of the system can improve timing consistency, while the selectable output division allows a practical audio-clock rate to be produced without a separate programmable synthesizer. Because the supplied web data does not enumerate every programmable frequency, jitter value, output format, or loop filter setting, those details must be confirmed in the manufacturer datasheet before final clock-tree validation. Typical uses include set-top box clock trees, multimedia receivers, DVD and digital-audio equipment, network equipment requiring stable derived clocks, and embedded audio systems where a single reference must feed several clock domains. The device is also appropriate for industrial control equipment when its specified operating range, electrical limits, and environmental qualifications match the system requirements. When laying out an MK2703SILF design, place the device and its associated crystal or clock-source components close to the circuit being clocked, keep output routes short, and provide return paths that do not share high-current switching paths. Confirm crystal load capacitance, output series termination, supply bypassing, and all supported output frequencies from the manufacturer datasheet before production release. This product record combines verified distributor and manufacturer information, traceable source links, honest specification gaps, and engineering-oriented application guidance. It distinguishes documented facts from parameters that still require verification, helping engineers evaluate the MK2703SILF without treating incomplete distributor summaries as a complete electrical datasheet.

In an MPEG-derived architecture, the device reduces the need for separate clock-generation logic. In standalone mode, it provides a controlled clock path from the specified crystal source. Designers should still evaluate startup time, lock behavior, output format, and signal integrity against the exact system timing requirements. The main design consideration is source and package verification. Confirm the exact pin mapping, supply requirements, crystal network, output enable behavior, and decoupling recommendations in the official Renesas MK2705 datasheet. Because the supplied web data does not include those detailed values, the appropriate engineering approach is to treat them as required design inputs rather than inferred specifications. This page consolidates verified distributor and manufacturer information, distinguishes confirmed facts from missing parameters, and provides practical application guidance for engineers evaluating the MK2705STR.
MK2712S - 35.469MHz NTSC/PAL Clock Source | Renesas
The Renesas Electronics MK2712S is an NTSC/PAL clock source with a listed operating frequency of 35.469 MHz, supplied in an 8-pin SOIC package measuring 3.90 mm wide. It is intended to generate the clocks required by compatible NTSC and PAL video encoders and decoders. The verified distributor description identifies the device as a clock synthesizer and video IC, while the manufacturer document identifies the MK2712 family as a dedicated NTSC/PAL clock-source solution. What is an NTSC/PAL clock source? It is a specialized clock and timing integrated circuit that supplies predictable video-system timing to encoder or decoder circuitry. NTSC and PAL are legacy analog video standards with different timing relationships, and compatible logic may require a stable reference rather than a general-purpose oscillator. Within the clock and timing hierarchy, the MK2712S belongs to the clock generator and frequency synthesizer class, supporting video clock generation within a broader timing-IC and semiconductor system. The available verified information confirms one clock value, 35.469 MHz, and an 8-pin SOIC package with a stated width of 3.90 mm. A third-party technical result also states that the family stores two sets of popular frequencies for NTSC and PAL, allowing clock generation with fewer external components than a discrete implementation. This integration can reduce board area and component count when its fixed outputs match the target video circuitry. Supply voltage, current consumption, output waveform, frequency tolerance, and temperature range were not included in the supplied evidence and therefore remain unconfirmed here. Architecturally, the device is presented as a dedicated clock source rather than a general-purpose phase-locked loop. Such fixed-function timing can simplify legacy video designs because engineers do not need to derive every standard-specific clock with separate dividers or oscillators. The exact selectable outputs, control method, and electrical timing characteristics must be confirmed in the Renesas MK2712 datasheet before layout or production release. Typical uses include NTSC video encoders, PAL video encoders, NTSC decoders, PAL decoders, industrial video equipment, broadcast-interface circuitry, and legacy video test systems. It is most appropriate where the downstream circuitry specifically expects the supported MK2712 clock outputs and where an 8-pin SOIC footprint fits the existing mechanical constraints. A key design practice is to follow the manufacturer reference connection and pin definitions exactly. Confirm signal levels, decoupling, exposed routing requirements if any, output availability, and timing margins against the official MK2712 datasheet before substitution. Because the supplied evidence does not establish an electrically interchangeable modern replacement, any alternate part should be treated as a new design until its pinout and output behavior are verified.

Typical uses include NTSC video encoders, PAL video encoders, NTSC decoders, PAL decoders, industrial video equipment, broadcast-interface circuitry, and legacy video test systems. It is most appropriate where the downstream circuitry specifically expects the supported MK2712 clock outputs and where an 8-pin SOIC footprint fits the existing mechanical constraints. A key design practice is to follow the manufacturer reference connection and pin definitions exactly. Confirm signal levels, decoupling, exposed routing requirements if any, output availability, and timing margins against the official MK2712 datasheet before substitution. Because the supplied evidence does not establish an electrically interchangeable modern replacement, any alternate part should be treated as a new design until its pinout and output behavior are verified.
MK2716S - 74.25MHz HDTV Clock Synthesizer | Renesas
The Renesas Electronics MK2716S is an HDTV clock synthesizer operating at 74.25 MHz and packaged in an 8-pin SOIC measuring 0.154 inches, or 3.90 mm, in width. Search results identify the device as a clock synthesizer and video IC with PLL-based frequency synthesis for video timing applications. The component is associated with the MK2716 family and is offered in tube packaging according to the supplied distributor records. A clock synthesizer is a timing IC that generates or distributes clock signals required by digital systems. In a PLL-based implementation, a phase-locked loop compares a reference signal with a divided output and adjusts the controlled oscillator until the two signals are synchronized. Clock synthesizers belong to the clock and timing IC hierarchy and support video, communications, and other systems that require stable reference-derived timing. The verified data identifies the MK2716S as a single PLL clock synthesizer, an HDTV clock synthesizer, and a 74.25 MHz device in an 8-pin SOIC package. These descriptions indicate a specialized timing function rather than a general-purpose oscillator or microcontroller. The exact output configuration, reference frequency, voltage ratings, jitter, pin functions, and operating limits are not present in the supplied verified records and must be confirmed in the manufacturer datasheet before design release. The part is associated with HDTV and video clock-generation requirements. A synthesized clock can provide a controlled timing reference to video-processing chains, display equipment, converters, and related digital video systems. The 74.25 MHz designation is a concrete nominal operating point in the provided distributor record, but the supplied data does not establish tolerance, output count, or configuration details. For PCB design, verify the exposed SOIC footprint, pin assignment, power rails, ground-return requirements, and recommended decoupling directly from the current Renesas datasheet. Do not substitute a generic clock IC solely because its frequency is similar; clock polarity, edge relationships, jitter, supply voltage, and system timing requirements must match. This page consolidates verified distributor descriptions, manufacturer-document references, packaging information, and engineering guidance. It does not infer missing electrical specifications, and unsupported values are marked for data completion rather than guessed.
MK2716SLF - 74.25MHz HDTV Clock Synthesizer | Renesas
The Renesas Electronics MK2716SLF is a 74.25 MHz HDTV clock synthesizer packaged in an 8-pin SOIC measuring 0.154 inch, or 3.90 mm, in width. The verified distributor data identifies one output and a 3 V to 5.5 V supply range. Its fixed 74.25 MHz frequency is associated with conventional HDTV video timing systems, where a stable common clock is needed by multiple digital video processing blocks. The surface-mount SOIC package supports automated board assembly, while the small footprint suits equipment where board area is constrained. A clock synthesizer is a timing IC that derives one or more predictable clock outputs from a stable frequency source. Within the clock and timing hierarchy, a clock synthesizer belongs to oscillator and clock-generation circuitry, which supports digital logic, video processing, communications, and other sequential systems. The MK2716 series is specifically described by Renesas as an HDTV clock synthesizer and is intended to replace discrete crystal-and-oscillator arrangements with a dedicated timing component where appropriate. The verified product information establishes a 74.25 MHz output, one available clock output, and a 3 V to 5.5 V operating supply range. These three characteristics make the device relevant to legacy or specialized HDTV designs that operate from standard low-voltage rails. Because the supplied snippets do not state the complete electrical characteristics, designers should consult the Renesas MK2716 datasheet before establishing output amplitude, input-frequency tolerance, jitter, power consumption, temperature limits, or timing margins. The MK2716's fixed clock output simplifies system partitioning when downstream circuits already require the 74.25 MHz HDTV reference. It can feed digital video timing, synchronization, interface-conversion, or processing blocks, provided their input levels and clock requirements match the device. Compared with a discrete crystal oscillator network, an integrated synthesizer can reduce component count and standardize clock generation, but it must still be supported by correct decoupling and controlled board layout. Typical implementation places the clock generator near the loads it serves and connects its supply to a clean 3 V to 5.5 V rail. Short traces help limit added delay and susceptibility to noise. The SOIC package requires adequate spacing from board edges and neighboring components, while the power and ground pins must follow the manufacturer's recommended layout. Load capacitance, fanout, and termination should be checked against downstream requirements. The key design trade-off is specialization. A dedicated 74.25 MHz HDTV clock synthesizer is appropriate when the system requires that reference, but it is not a universal programmable clock solution. Confirm source frequency, output count, supply voltage, logic levels, package, and pinout against the current manufacturer datasheet before layout release. This page distinguishes verified facts from parameters that were not present in the supplied data.

It is identified by distributor listings as a clock generator, PLL, and frequency synthesizer intended for systems requiring a stable local frequency source. The verified data specifically confirms the device category, nominal 27 MHz frequency, VCXO function, PLL clock synthesizer function, and 8-SOIC package. A PLL clock synthesizer is a clock-and-timing integrated circuit that generates, conditions, or multiplies timing references for digital and RF systems. The MK2727S combines a PLL clock synthesizer with VCXO behavior, placing it within the broader hierarchy of clock management, timing control, and semiconductor signal-processing devices. This type of component is relevant when a system needs frequency flexibility, stable clock distribution, or a local oscillator rather than a fixed passive resonator alone. The principal verified feature set is compact but application-defining: a 27 MHz operating reference, VCXO functionality, PLL clock synthesis, and an 8-SOIC package. The available distributor listings describe the part as suitable for clock-generation requirements and compare inventory across multiple suppliers. The package is small enough for conventional surface-mount PCB assembly while remaining compatible with standard 8-pin SOIC footprint checks. Technically, the MK2727S belongs to the clock-and-timing segment rather than a power-management or signal-amplifier category. Its usefulness depends on the required output frequency, tuning range, phase-noise behavior, supply requirements, reference architecture, and downstream clock tolerances. Those detailed electrical limits are not provided in the verified excerpts and must be checked against the official Renesas MK2727 datasheet before final schematic approval, timing-budget closure, or PCB release. Typical design roles include local clock generation for embedded systems, frequency reference conditioning in communications equipment, timing support in RF systems, and synchronization in test or measurement platforms. The verified Xecor comparison describes the MK2727 family as a frequency source for 2.4 GHz and 5 GHz systems, while the manufacturer datasheet page is the authoritative source for electrical limits and application guidance. The most important design practice is to verify the complete electrical and timing specification set rather than selecting from the distributor headline alone. Designers should confirm reference input type, output arrangement, supply voltage, tuning interface, temperature range, and pin-level truth table in the manufacturer datasheet. This page distinguishes verified facts from unavailable parameters and avoids treating distributor classifications as substitutes for engineering specifications. This product data consolidates verified distributor listings, the official Renesas datasheet link, package information, and application context for engineers evaluating the MK2727S. It is intended to support initial sourcing and design screening, while final qualification remains dependent on the full manufacturer datasheet and application-specific validation.

Renesas Electronics MK2727SLF is a 27 MHz voltage-controlled crystal oscillator with an integrated phase-locked loop, classified in verified listings as a PLL clock synthesizer, VCXO, or clock generator with one clock circuit. The device accepts a crystal input, produces a CMOS clock output, and is packaged in an 8-pin SOIC measuring 0.154 inch wide and 3.90 mm in width. Its maximum stated frequency is 27 MHz. A VCXO is a crystal oscillator whose output frequency can be adjusted by an external control voltage. Adding a phase-locked loop allows the oscillator frequency to be stabilized against a reference, making this device part of the clock-generation and frequency-synthesis hierarchy. In system terms, the MK2727SLF is a Clock & Timing IC that converts a crystal input into a controlled CMOS output suitable for clocking or frequency-reference functions. The verified part description identifies the MK2727SLF as a low-cost 27 MHz VCXO. It uses a crystal input, provides a CMOS output, and contains one clock circuit. These characteristics make frequency stability and external control central to its selection. The 8-SOIC package also provides a conventional surface-mount footprint, although pin assignments, voltage limits, control sensitivity, and output-drive details must be confirmed directly from the manufacturer datasheet before layout or replacement work. Technically, the MK2727SLF combines a crystal oscillator with PLL-based frequency control. Such an arrangement can reduce long-term frequency variation relative to an uncompensated crystal oscillator by locking the controlled oscillator to a reference. However, loop bandwidth, capture range, tuning voltage, reference requirements, and phase-noise performance are not present in the supplied verified excerpts, so those values should not be inferred from the 27 MHz headline specification. Typical applications for this device include communication modules, industrial control electronics, embedded equipment, and other systems requiring a tunable or PLL-stabilized CMOS clock. The single-circuit architecture is appropriate where one local clock domain is needed. Care is required when multiple clock domains exist because the supplied data confirms only one clock circuit and does not establish independent output-channel behavior. For a robust design, verify the complete pinout, recommended crystal load, bypass-capacitor values, control-voltage range, and output impedance from the eight-page manufacturer datasheet. Confirm loop stability and startup behavior in the target reference configuration. Do not treat the distributor summary as a substitute for the datasheet when selecting crystal parameters or determining PCB land patterns. This product record consolidates the verified 27 MHz VCXO description, PLL and CMOS classifications, 8-SOIC package information, source listings, and engineering guidance. It also distinguishes confirmed characteristics from parameters that still require datasheet-level verification, reducing the risk of selecting or replacing the MK2727SLF from incomplete catalogue information.

The device combines a voltage-controlled crystal oscillator, PLL, and multiplier functions in one package. A VCXO, or voltage-controlled crystal oscillator, is a crystal-based frequency source whose output frequency can be adjusted with an external control voltage. A phase-locked loop, commonly abbreviated as PLL, is a feedback control system that synchronizes an oscillator to a reference frequency and multiplies that frequency. The MK2732-06G therefore sits within the clock and timing IC hierarchy as a programmable clock generator, frequency synthesizer, and VCXO timing device. The MK2732-06G accepts a crystal input and provides a CMOS clock output. Its maximum operating frequency is 54 MHz, and it contains one clock circuit with an input-to-output ratio of 1:3. The on-chip VCXO accepts a tuning voltage from 0 V to 3 V, allowing the output clock to vary by plus or minus 100 ppm. The documented pull range is 200 ppm from the minimum tuning voltage of 0 V to the maximum of 3 V. The device includes PLL bypass capability and is intended to replace combinations of discrete VCXOs and frequency multipliers. This integration can reduce the number of separate clock components required in a design while preserving an adjustable output. The specified use cases include xDSL chipsets and MPEG-2 decoders, where deterministic local clock generation can support data conversion and multimedia processing systems. Typical applications include xDSL chipset clocking, MPEG-2 decoder timing, communication equipment, and other systems requiring a crystal-referenced CMOS clock with voltage-controlled frequency adjustment. The 16-pin TSSOP package supports surface-mount assembly and is compatible with compact PCB layouts. Its 4.40 mm body width places it in the TSSOP-16 surface-mount package family. Designers should treat crystal selection, VCXO control-voltage filtering, and output-clock jitter as an integrated design task. Decoupling, grounding, and short clock traces remain important because switching noise at the reference input can degrade clock quality. The manufacturer datasheet should be consulted for the complete pin assignment, recommended crystal circuit, electrical limits, and timing characteristics before layout is released. This product record combines the verified Renesas and distributor descriptions with engineering guidance covering the VCXO, PLL, 54 MHz maximum frequency, 3 V tuning range, 200 ppm pull range, CMOS interface, and 16-TSSOP package. It also distinguishes verified device facts from values that require confirmation from the manufacturer datasheet.
MK2745-21S - 80MHz DVD/MPEG Clock Synthesizer | Renesas
The Renesas Electronics MK2745-21S is a low-cost, low-jitter clock/frequency synthesizer IC with a maximum output frequency of 80 MHz, packaged in a 16-pin SOIC. It uses an analog phase-locked loop to generate multiple audio output clocks, a processor clock, a divided processor clock, a 27 MHz clock, and additional timing signals for DVD and other MPEG-2-based systems. The device accepts a 27 MHz fundamental-mode crystal or clock input and supports clock or crystal sources with CMOS outputs. A clock synthesizer is a timing-control IC that uses a phase-locked loop to establish an output clock from a stable reference. In the electronics hierarchy, the MK2745-21S is a clock/frequency synthesizer, a clock-and-timing IC, and a power-management-adjacent system-timing component. Its purpose is to distribute related clock signals accurately within a multimedia or consumer-electronics system, reducing the number of separate oscillators and clock-generation circuits required on the printed circuit board. Key features include an 80 MHz maximum output frequency, an analog PLL architecture, CMOS output logic, and support for either a crystal or external clock input. The 27 MHz reference arrangement is particularly relevant to DVD and MPEG-2 equipment, where several audio and processor-related clocks must share a common reference. According to the Renesas manufacturer datasheet, the device is positioned as a low-cost, low-jitter, high-performance clock synthesizer for these applications. Technically, the analog PLL multiplies or divides the reference frequency to develop the required output-clock relationships. Because the reference source and generated outputs are phase-related, the part is intended to provide coherent timing across multiple audio and processor domains. The available specifications identify one PLL circuit, clock or crystal input, and a maximum frequency of 80 MHz. Detailed jitter, output-accuracy, voltage, and temperature limits are not available in the supplied verification excerpts and should be confirmed in the manufacturer datasheet before precision-timing design sign-off. Typical applications include DVD players, MPEG-2-based multimedia systems, set-top equipment, audio processing platforms, and other embedded products requiring a 27 MHz reference and derived clocks. In these systems, the MK2745-21S can replace separate oscillator and divider arrangements where its supported output set and electrical limits satisfy the design. The benefit is centralized clock management, while the tradeoff is dependence on correct reference configuration, output-enable sequencing, board-level return paths, and stable supply voltage. The primary design consideration is to verify every generated frequency and logic level against the exact system timing tree. Layout should provide a short, clean 27 MHz reference path, a controlled crystal or clock source, and low-impedance ground connections. Decoupling and unused-pin handling must follow the manufacturer datasheet, because incorrect implementation can add reference noise or create unintended clock activity even when the nominal output frequencies are correct. This page consolidates the verified manufacturer and distributor information, documents missing electrical details without guessing, compares the available same-family Renesas option, and provides application-specific design guidance. It is intended to support component identification, sourcing, and preliminary engineering evaluation while clearly separating confirmed specifications from parameters that still require datasheet review.
MK2745-24S - 160 MHz DVD/MPEG Clock Synthesizer | Renesas
The Renesas MK2745-24S is a low-cost, low-jitter clock synthesizer with PLL bypass for DVD and other MPEG-2-based equipment. It accepts a 27 MHz fundamental-mode crystal or clock input, uses analog phase-locked-loop techniques, and generates multiple audio output clocks, a processor clock, and two 27 MHz clocks. The device produces CMOS outputs, contains one clock-synthesis circuit, supports a maximum frequency of 160 MHz, and provides a maximum input-to-output ratio of 1:8. A clock synthesizer is a timing IC that derives one or more internally related clock signals from a common reference. Clock generators, phase-locked loops, and frequency synthesizers form the broader clock and timing IC category. By coordinating audio, processor, and reference clocks in one device, the MK2745-24S reduces the number of separate oscillators required by DVD, MPEG-2, set-top, and related multimedia systems. Its bypass mode provides a direct clock path when PLL operation is not required. Key features include a 27 MHz crystal or clock input, CMOS output technology, analog PLL operation with bypass, a maximum output frequency of 160 MHz, and an input-to-output ratio reaching 1:8. These characteristics suit designs that require multiple related clock domains while limiting board area. The single-circuit architecture is appropriate for centralized system timing rather than applications requiring numerous independent programmable outputs. The device is intended for DVD and MPEG-2-based multimedia platforms where processor timing, audio clocks, and 27 MHz reference clocks must remain related. Its architecture can reduce clock-generation complexity by sharing a common reference across multiple outputs. Engineers should still evaluate each output's frequency, jitter, drive level, and operating condition against the complete system timing budget before releasing a production design. Typical uses include DVD player clock trees, MPEG-2 set-top boxes, digital audio systems, processor clock generation, and multimedia equipment requiring 27 MHz references alongside derived audio or processor clocks. It may also be evaluated for legacy industrial and embedded video systems that use a 27 MHz source and CMOS-compatible clock inputs. The primary design consideration is that the verified source excerpt does not identify the exact package, pin count, supply voltage, or complete output-frequency mapping. Those details must be confirmed in the Renesas MK2745-24 datasheet before schematic capture or PCB layout. The suffix and programming or packaging options should not be assumed equivalent unless the manufacturer data explicitly confirms them. This page combines verified manufacturer and distributor information, pricing placeholders, drop-in-replacement verification status, and practical selection guidance. Unlike a raw distributor listing, it also identifies missing package and pinout data, distinguishes confirmed functions from unverified specifications, and explains where engineers must perform final datasheet validation.
MK2746-01G - 27MHz USB-DVR Clock Synthesizer | Renesas
Renesas Electronics MK2746-01G is a low-cost, low-jitter clock and frequency synthesizer with a 27 MHz maximum output frequency, analog PLL with bypass capability, and CMOS outputs in a 16-pin TSSOP package. It accepts either a 27 MHz fundamental-mode crystal or clock input and is designed to generate the multiple clocks required by USB and video systems. The device includes one clock synthesizer circuit and provides an input-to-output ratio listed as 2:5 in the verified specifications. A clock synthesizer is a clock-and-timing IC that uses a phase-locked loop (PLL) to derive stable, related output frequencies from a reference source. Within the broader hierarchy of clock and timing ICs, frequency synthesizers sit above basic clock generators and below application-specific timing systems. The MK2746-01G belongs to this clock-and-timing category because it combines a reference input, analog PLL frequency multiplication, and CMOS clock outputs intended for USB-DVR equipment. The key feature of the MK2746-01G is its 27 MHz operating reference combined with analog PLL technology. A bypass path allows the reference clock to pass through without multiplication, which can simplify clock-tree design and support test or low-jitter operating conditions. The single-circuit implementation reduces the number of separate frequency-generation blocks required in a USB-DVR design, while the CMOS output interface connects directly to compatible downstream digital circuitry. The MK2746-01G is specified as a low-cost, low-jitter, high-performance clock synthesizer intended specifically for USB-DVR applications. Its 2:5 input-to-output ratio provides a defined multiplication relationship for designs operating from the specified 27 MHz reference. The 16-pin TSSOP package measures 4.40 mm in body width according to the verified distributor data, making it suitable for compact consumer-electronics and set-top-box layouts where a larger clock-generator package would be inconvenient. Typical uses include USB-DVR clock trees, USB interface timing, video timing systems, and compact consumer-electronics products that require multiple related clocks. In these systems, the crystal or external clock establishes the reference, the PLL generates the required multiplied clock, and the CMOS outputs distribute timing signals to USB and video functional blocks. The availability of PLL bypass provides an additional implementation option where preserving the reference clock may be desirable. Designers should confirm the complete output-frequency list, exact crystal-load requirements, output-drive configuration, supply limits, and pin-level connectivity in the Renesas MK2746 datasheet before layout release. Only the 27 MHz maximum frequency, analog PLL with bypass, CMOS output type, 2:5 ratio, single-circuit count, and 16-TSSOP format were confirmed by the supplied web data. Values not explicitly present in that data are identified separately rather than inferred. This product record combines verified manufacturer and distributor specifications, current sourcing information, a confirmed direct replacement, and practical implementation guidance. It distinguishes confirmed electrical facts from unavailable details, helping engineers evaluate the MK2746-01G for USB-DVR clock generation without relying on unverified assumptions.
