It is designed to consolidate oscillator and PLL functions in multimedia systems and set-top boxes. A PLL clock synthesizer multiplies or organizes a reference clock into a stable operating or audio sampling clock. In the signal path, it belongs to clock and timing ICs, where its role is to generate predictable digital timing from a crystal or external reference. The available ratio of 1:2 indicates that this device family is intended for a defined clock-generation relationship rather than general-purpose fractional-N synthesis. Key verified features include PLL operation with bypass, clock or crystal input, one clock circuit, and a CMOS output. The bypass path is useful during startup, test, or mode transitions, while the PLL path supports synthesized clock generation. The 36.864MHz maximum frequency makes the device applicable to multimedia timing systems operating around common digital audio-related clock domains, subject to the complete manufacturer datasheet limits. The MK2704STR uses a single 8-pin SOIC package according to the available distributor records. The package supports conventional surface-mount assembly and can simplify board replacement compared with discrete oscillator-plus-divider assemblies. Its architecture is intended to replace separate oscillator and PLL circuits in set-top box and multimedia equipment, reducing board count while centralizing clock generation. Typical uses include set-top box clock generation, multimedia system timing, digital audio interfaces, and other embedded systems requiring a CMOS clock with bypass control. When designing around the device, verify crystal start-up requirements, output loading, supply voltage, and all operating conditions against the manufacturer datasheet. Because the supplied evidence is distributor-oriented and does not include a complete official parametric table, unverified values are not inferred. This product page combines verified source snippets, application guidance, source links, and engineering caveats rather than inventing electrical ratings. It distinguishes known specifications from fields that require confirmation in the manufacturer datasheet, helping engineers identify the MK2704STR quickly while avoiding unsupported claims.

MK2705STR - MPEG Audio Clock Synthesizer | Renesas

The Renesas MK2705STR is an integrated audio clock synthesizer that generates synchronous sampling-clock rates derived from an MPEG stream and can also operate as a standalone clock source using a 27 MHz crystal. Its verified device classification includes one PLL, clock or crystal input, and clock output, with a documented 1:1 input-output ratio. The part is supplied in an 8-pin SOIC package, making it suitable for compact digital audio, MPEG decoder, and consumer-electronics clock architectures. A clock synthesizer is a clock-and-timing integrated circuit that creates, distributes, or translates timing signals for another circuit. In an MPEG audio system, the synthesizer derives the sampling rate required by an audio decoder or interface. This clock-generation function sits within the broader timing hierarchy of a PLL, clock generator, clock and timing IC, and ultimately system clock infrastructure. The MK2705 supports both stream-derived operation and standalone operation, allowing a design to cover multiple source conditions. The verified feature set emphasizes integration rather than a broad set of published numeric ratings. It includes PLL capability, one clock circuit, clock or crystal input, clock output, and an input-to-output ratio of 1:1. Search results identify the primary use as MPEG audio, while the 27 MHz crystal mode provides a reference for designs that do not require an MPEG-derived source. These details make the device directly relevant to audio sampling-clock generation rather than general-purpose distribution. The MK2705STR belongs to the clock-and-timing hierarchy and is listed as an audio clock source in distributor results. That classification distinguishes it from oscillators, microcontrollers, and ordinary fixed-function logic. A PLL can phase-lock and derive a stable output frequency from a source, while the integrated clock output routes the generated timing signal within the audio subsystem. The supplied evidence does not provide verified operating voltage, frequency range, jitter, phase-noise, or power-consumption figures, so these values must be confirmed in the Renesas datasheet before production design. Typical uses include MPEG audio decoder boards, digital audio sampling-clock generation, multimedia clock trees, and systems where a 27 MHz crystal reference is available. 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

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.

Video clock synthesizers are used when multiple video functions must share a stable, defined timing relationship, particularly in broadcast, capture, processing, and display equipment. The verified product listing identifies the MK2712SLF as a clock synthesizer and video IC with one channel, a 35.469 MHz nominal frequency, and an 8-SOIC package. Distributor information also describes it as an NTSC/PAL clock source. These characteristics make frequency stability, output behavior, supply requirements, and timing margins the primary engineering concerns when evaluating this device for a new video design. The MK2712SLF is used where the system requires a dedicated video timing reference rather than a general-purpose clock. Its single-channel architecture is appropriate for designs that establish a central NTSC/PAL-related timing point and distribute that reference to other circuit blocks. Designers should confirm that the generated frequency matches every video standard and timing requirement in the target system before releasing production hardware. Typical uses include video capture systems, broadcast-equipment clocking, NTSC/PAL-compatible processing chains, and multi-function video boards. In these applications, the clock reference establishes timing for video signal generation and downstream conversion or processing. Because different video standards use different timing parameters, a fixed 35.469 MHz source must be integrated only where its timing role is understood and validated. The principal design consideration is verification of the complete clock path. Evaluate output frequency, tolerance, jitter, noise, supply range, and logic levels against the downstream video ICs before layout. Decoupling and return paths should follow the requirements in the manufacturer datasheet, and unused outputs or control pins must not be assigned functions without confirmation from that document. This page combines the verified Renesas and distributor information with practical procurement context, explicit data gaps, package details, and a conservative review of available video-clock alternatives. It is designed to help engineers distinguish confirmed MK2712SLF facts from characteristics that still require datasheet-level verification.

The MK2712SLFTR provides one clock circuit, a maximum listed frequency of 35.469 MHz, PLL support, clock input, and CMOS output. These characteristics distinguish it from general-purpose fixed-frequency oscillators and make it applicable where NTSC or PAL video timing is required. The single-circuit architecture also keeps the device focused on a compact legacy-video timing function rather than a multi-output modern clock-tree role. The 8-SOIC package measures 0.154 inches wide, corresponding to a 3.90 mm package width, and is identified by the LFTR ordering code. Its eight pins provide the physical interface for power, ground, clock input, control, and generated timing signals. Exact pin names, voltage ratings, operating-temperature limits, and timing tolerances should be taken from the manufacturer pin-description table when assigning PCB nets or evaluating signal timing margins. Typical MK2712SLFTR applications include NTSC and PAL video timing generation, analog video processing equipment, broadcast-related clocking, and legacy video test systems. In each case, the device can establish the foundational timing reference used by downstream synchronization logic. Its single clock circuit suits systems that require a dedicated video-standard clock without a larger multi-channel timing architecture. Designers should verify output frequency tolerance, input-reference requirements, PLL lock behavior, and logic thresholds against the manufacturer datasheet before layout is released. Decoupling and signal-routing practices should follow the reference circuit associated with the selected device, while unused inputs require the prescribed bias states. Because timing specifications are sensitive to trace loading and supply integrity, short clock routes and a stable local supply connection are important. This page combines the verified device identity, package and clock-source characteristics with a drop-in comparison, application guidance, and practical design considerations. It is intended to help engineers identify the correct legacy video timing device, confirm package compatibility, and plan a clock-source implementation without relying on generic oscillator-selection guidance.

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 MK2716STR 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.

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.

Renesas MK2732-06G is a low-cost, low-jitter VCXO and PLL clock synthesizer with a maximum frequency of 54 MHz, crystal input, CMOS output, and a 16-pin TSSOP package rated at 0.173 inch, or 4.40 mm, width. 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.

MK2732-06GLF - 5V VCXO-PLL Clock Synthesizer | Renesas

Renesas Electronics MK2732-06GLF is a low-cost, low-jitter clock synthesizer combining a voltage-controlled crystal oscillator, phase-locked loop, and clock-multiplier functions in a lead-free 16-pin TSSOP package. It operates from a 4.75 V to 5.25 V supply and uses CMOS-compatible clock interfaces. The integrated VCXO accepts a 0 V to 3 V control voltage, allowing its output frequency to vary by up to ±100 ppm for clock adjustment in communications, test, and signal-processing systems. A clock synthesizer is a timing IC that derives one or more stable output clocks from a reference source. A VCXO provides voltage-controlled frequency adjustment, while a PLL multiplies and cleans up the reference frequency. The MK2732-06GLF therefore occupies the clock and timing hierarchy between a crystal reference and the digital clock inputs of processors, converters, transceivers, and test equipment. Renesas describes the device as a low-cost, low-jitter, high-performance alternative to separate VCXO and frequency-multiplier assemblies. Its principal benefits are integration, reduced component count, adjustable output frequency, and low phase noise. The on-chip control range supports fine tuning when compensation is required for crystal tolerance, temperature drift, propagation delay, or synchronization between independently clocked subsystems. The device combines a VCXO with PLL synthesis to provide multiple clock outputs from a common reference arrangement. CMOS-compatible signaling supports integration into digital logic, while the integrated architecture avoids the component count and interconnect complexity of a discrete oscillator followed by a separate multiplier. The exact output frequency, divider ratios, output configurations, and jitter limits depend on the selected crystal, programming method, and operating configuration documented for the MK2732-06 family. Typical uses include clock recovery, communication timing, frequency conversion, instrumentation, and low-cost oscillator replacement. The part can also serve wherever a reference crystal must be converted into one or more digital clock domains with controlled phase noise. Systems requiring a variable frequency can apply an external control voltage to the VCXO input and use the synthesized output as the system timing reference. Designers should verify the crystal frequency, loop filter or programming requirements, output enable behavior, and all supply and ground connections in the manufacturer datasheet before layout release. Decoupling should be placed close to the supply pins, while the oscillator and feedback paths should remain compact and isolated from high-current switching nodes. Because the clock output edge can carry reference noise, leave adequate isolation around sensitive timing paths. This product page combines manufacturer and distributor information with package-specific identification, application guidance, design considerations, and a conservative replacement assessment.

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.

Typical uses include DVD and MPEG 2 player mainboards, optical-disc playback systems, set-top equipment, and multimedia processors requiring coordinated audio and processor clocks. It is also appropriate for legacy equipment repairs where replacing a surface-mount clock-source IC without altering the existing board layout is important. For a new design, verify every required output frequency, supported reference mode, voltage rail, load, and package footprint before committing the 16-pin SOIC footprint. Crystal selection and PLL loop components are timing-critical, so use the reference values and layout guidance in the manufacturer datasheet. Decoupling should be placed close to the supply pins, and unused outputs should be handled according to the device's output-drive and no-connect guidance. This product page combines the Renesas device description with package information, verified sourcing links, engineering-oriented application guidance, and a parameter-by-parameter replacement comparison. It is intended to help engineers identify the correct clock-source function, assess board compatibility, and plan a qualified replacement or repair before layout changes are made.

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.
