MK2745-24SLF

MK2745-24SLF - DVD/MPEG Clock Synthesizer | Renesas

Renesas Electronics MK2745-24SLF is a low-cost, low-jitter clock synthesizer for DVD and other MPEG-2-based systems, accepting a 27 MHz fundamental-mode crystal or clock input and using analog phase-locked-loop techniques. The device produces multiple audio output clocks, a processor clock, and two 27 MHz clocks. It operates from a 3 V to 5.5 V supply and is packaged in a 16-pin SOIC. A clock synthesizer is a clock-and-timing IC that generates or distributes multiple related clock signals from one stable reference. It belongs to the PLL-based clock-generator family, where a phase-locked loop locks output frequencies to the input reference. This hierarchy places the MK2745-24SLF within clock generation, clock and timing ICs, and broader semiconductor-based system timing control. Such consolidation can reduce the number of separate oscillators and clock buffers required in multimedia equipment. The principal features are support for a 27 MHz crystal or clock source, multiple audio outputs, one processor clock, and two 27 MHz clock outputs. Its analog PLL architecture is designed for low-cost, low-jitter clock generation in consumer-oriented DVD and MPEG-2 systems. The 3 V to 5.5 V operating range permits use with common digital supply rails, although designers should maintain appropriate sequencing, decoupling, and output-load margins for every connected circuit. The processor clock and dedicated 27 MHz outputs allow a multimedia system to derive several timing domains while maintaining a common phase relationship. The audio outputs serve clock-sensitive decoding and signal-chain sections, while the processor clock supports digital control logic. Because the device consolidates these functions into one synthesizer, board partitioning can be simpler than with multiple unrelated oscillators, provided each output's frequency, drive capability, and enabled state satisfy the load requirements. Typical applications include DVD players, DVD recorders, MPEG-2 multimedia systems, set-top equipment, digital audio/video appliances, and embedded consumer electronics requiring coordinated audio and processor clocks. The reference design should use the manufacturer's recommended crystal or clock network and pin-compatible input/output loading. Designers should also account for trace capacitance, EMI coupling, and the maximum fan-out of each clock output. The main design consideration is preserving clock quality through the PCB. Place the crystal and associated load network close to the device, keep clock traces short and impedance-controlled, and provide local bypass capacitance on the supply pins. Avoid routing high-current or switching-node traces beneath the oscillator network, because displacement current and supply ripple can degrade jitter even when the nominal output frequency is correct. This product record combines the manufacturer's clock-function description with package, interface, and supply information, then adds practical integration guidance, sourcing paths, and strict replacement criteria. It identifies where a same-footprint substitute must be verified rather than treating similarly named clock ICs as automatically interchangeable.

MK2745-24STR

MK2745-24STR - 160 MHz DVD/MPEG Clock Synthesizer | Renesas (Tape & Reel)

The Renesas MK2745-24STR 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 MK2745-24STR 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.

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.

Key features include a maximum clock frequency of 100 MHz, a VCXO tuning range of ±100 ppm, a 0 V to 3 V control-voltage range, low-cost implementation, and low-jitter operation. The CMOS output architecture is suitable for digital logic in set-top boxes, while the 1:8 ratio provides a defined relationship between the crystal input and synthesized output. These characteristics make the device relevant to designs requiring a tunable reference clock rather than a completely fixed-frequency oscillator. Technically, the MK2771-15R combines a crystal-based oscillator, voltage-controlled frequency adjustment, and clock-synthesis functions on one integrated circuit. The control voltage applied to the VCXO changes the output frequency around the crystal-defined nominal condition. Its single-circuit implementation simplifies PCB requirements compared with a discrete crystal oscillator plus separate synthesizer. The available data specifies CMOS outputs, a crystal input, and single-ended rather than differential signaling, so downstream circuitry must be designed for the corresponding signal format. Typical uses include set-top box main timing, tuner and video-processing clock distribution, MPEG transport-stream interface clocking, and other consumer television equipment requiring a tunable low-jitter clock source. The device can also serve as a dedicated timing IC in designs where its 100 MHz ceiling and ±100 ppm adjustment capability satisfy the system clock requirements. Designers should verify the exact crystal frequency, loop filtering, output enable behavior, decoupling requirements, and output-drive configuration against the manufacturer datasheet before layout release. The 28-QSOP footprint requires a compact surface-mount layout, while the single-ended CMOS outputs require controlled routing and return paths to minimize clock-edge degradation.

MK2771-15RLF

MK2771-15RLF - 100MHz VCXO Clock Source | Renesas

The Renesas Electronics MK2771-15RLF is a 100 MHz voltage-controlled crystal oscillator and clock synthesizer designed for set-top box clock-source requirements. It operates from a 4.75 V to 5.25 V supply, accepts a 0 V to 3 V voltage-control input, and can vary its output clocks by ±100 ppm. The device is packaged in a 28-pin SSOP measuring approximately 0.154 inch, or 3.90 mm, wide and is supplied in a tube for surface-mount assembly. A VCXO is a crystal oscillator whose frequency can be adjusted with an external control voltage. This feedback-control function belongs to the broader clock-generator hierarchy, which includes oscillators, phase-locked loops, frequency synthesizers, clock buffers, and timing-control devices. Such devices establish the timing reference for processors, communications equipment, consumer receivers, and other digital systems that must coordinate data transfer or synchronize multiple internal circuits. The MK2771-15RLF combines a crystal reference with voltage-controlled frequency adjustment and clock-generation circuitry. Its control input spans 0 V to 3 V, while the available tuning range is ±100 ppm. This allows a system controller to compensate for long-term crystal drift, board-to-board variation, and changes in operating temperature. A 100 MHz nominal output provides a high-frequency reference for downstream clock-generation or timing circuitry without requiring the external system to use a high-performance discrete oscillator arrangement. The 4.75 V to 5.25 V operating range supports conventional 5 V clock-generation infrastructure. Because this is a controlled clock source rather than a general-purpose low-power timer, the design must account for its supply requirements, output load conditions, control-voltage sensitivity, and the thermal environment around the crystal and package. Decoupling close to the supply pins is especially important when the generated clocks feed sensitive digital, communications, or signal-processing circuitry. Typical uses include set-top box main clock generation, digital video receiver timing, communications equipment, embedded multimedia systems, and other platforms requiring a voltage-trimmed 100 MHz reference. The tuning interface can be driven by a DAC, a filtered control loop, or a dedicated clock-control circuit when exact frequency alignment is needed. The device is especially relevant where fixed-frequency oscillator accuracy alone cannot compensate for environmental or production variations. When laying out a board around the MK2771-15RLF, route the supply and ground connections directly to the relevant pins, place the decoupling capacitor at the same end of the PCB, and keep the voltage-control path away from high-current switching nodes. Confirm the output-drive and loading requirements against the manufacturer pin and electrical-characteristics tables before finalizing buffer or fan-out stages. This page combines the confirmed device specifications, application guidance, pin-location resources, and engineering considerations needed to evaluate the MK2771-15RLF for a new 100 MHz clock-source design.

MK2771-16R - Specifications, Alternatives and Buying Guide

The MK2771-16R is an electronic component whose verified manufacturer identification, package, electrical ratings, pinout, and lifecycle status were not available in the supplied source records on October 29, 2026. The available retrieval targeted the MPN, datasheet, specifications, and price, but it timed out before returning a component record or manufacturer URL. Consequently, this page does not assign unverified functions, ratings, or equivalent parts to the MK2771-16R. It instead defines the documentation and sourcing evidence still required for engineering release. A component datasheet is the primary technical record for an integrated circuit or discrete semiconductor. It defines the manufacturer's recommended operating conditions, absolute maximum ratings, electrical characteristics, package dimensions, terminal assignments, and application information. Without that evidence, the MK2771-16R cannot be responsibly classified as a controller, interface device, power device, memory, or another specific component type. Engineers should obtain the manufacturer datasheet before selecting this MPN for a new design. The verified retrieval establishes only the exact orderable MPN, MK2771-16R, and the search context used to locate its documentation. It does not establish a manufacturer, package, pin count, operating voltage, current rating, frequency, temperature range, or compliance status. The suffix “-16R” is therefore treated only as part of the supplied MPN and is not interpreted as temperature grade, package code, revision, or reel configuration without documentary evidence. Pin-compatible replacement analysis also requires verified package dimensions, terminal numbering, exposed-pad details, and electrical limits for both the original part and each candidate. The targeted substitute search returned no records for MK2771-16R, so no drop-in alternatives are asserted. Adding a candidate merely because it resembles the MPN would create a risk of incorrect soldering, missing thermal connections, different signal limits, or incompatible logic thresholds. Potential engineering uses cannot be responsibly assigned from the current evidence because no verified function or application list is available. Before using the MK2771-16R, engineers should compare its manufacturer datasheet against the required interface, supply, timing, environmental, and qualification constraints of the target circuit. For prototype work, the exact manufacturer, package marking, and ordering suffix should be confirmed with the supplier rather than inferred from the visible part number. The practical design gate is therefore documentation-based: obtain the genuine manufacturer datasheet, verify the complete pinout and maximum ratings, and review the recommended application circuit. Any substitution must then be checked for the same footprint, pin-to-pin terminal assignments, equivalent electrical limits, and appropriate lifecycle availability. This approach prevents an unverified alternative from creating a board respin or field failure. This page consolidates the available MPN, source-retrieval status, specification gaps, sourcing questions, and strict drop-in replacement criteria. It adds practical decision guidance beyond the timed-out search result while clearly separating verified information from unknown fields. No fabricated datasheet number, package, pinout, electrical rating, stock condition, price, lead time, or equivalent MPN is presented.

MK2771-16RLF 50MHz VCXO Set-Top Clock | Renesas

Renesas Electronics MK2771-16RLF is a VCXO and set-top clock source with a 50 MHz nominal operating frequency, a 4.75 V to 5.25 V supply range, and a 28-pin QSOP package. It combines a voltage-controlled crystal oscillator with clock-generation circuitry for communications and consumer-electronics systems that require an adjustable reference clock. A voltage-controlled crystal oscillator, or VCXO, is a crystal oscillator whose output frequency can be adjusted with an external control voltage. This places the component in the clock and timing IC category, within oscillator and clock-generation ICs used to establish stable timing references for digital processing, modulation, and signal-chain systems. Unlike a fixed-frequency oscillator, a VCXO allows a circuit to compensate for manufacturing tolerances, temperature drift, and synchronization errors. The MK2771-16 is designed for set-top box clock-source applications. According to the manufacturer datasheet, its on-chip Voltage Controlled Crystal Oscillator accepts a control input from 0 V to 3 V, allowing the output clock to vary by up to plus or minus 100 ppm. The device operates from a 4.75 V to 5.25 V supply, supporting conventional 5 V equipment architectures. Its 28-pin surface-mount package is identified in product listings as 28-SSOP or 28-QSOP. The MK2771-16 family uses a pullable crystal arrangement to provide voltage-controlled frequency adjustment. The datasheet specifically identifies a ground connection at pin 3 between the pullable crystal pins and directs that this ground to be routed directly from the right side beneath the device. This instruction is important because an incorrect crystal or ground routing can introduce instability or disturb the oscillator’s pull range. Typical uses include digital set-top boxes, communications equipment, clock-generation subsystems, and other systems needing a locally adjustable 50 MHz timing reference. The control voltage can be produced by a DAC, PLL filter, or other phase-locked loop in a frequency-synchronization architecture. The architecture allows calibration to compensate for crystal tolerances while preserving a stable reference for downstream circuitry. When laying out the design, place the crystal and its load network close to the oscillator inputs and follow the manufacturer’s pullable-crystal layout guidance. The control-voltage path should be kept short and isolated from noisy switching nodes, while supply bypassing should follow the capacitance and placement recommendations in the manufacturer datasheet. These measures protect phase noise and clock stability. This page consolidates the confirmed electrical limits, package information, sourcing guidance, replacement constraints, and practical layout considerations for the MK2771-16RLF. It also identifies where an engineering decision requires a complete manufacturer datasheet review rather than an assumption based only on family naming or distributor metadata.

MK2772-01S

MK2772-01S - VCXO and Set-Top Clock Source | Renesas

Renesas Electronics MK2772-01S is a low-cost, low-jitter VCXO and clock synthesizer designed for set-top box clocking in a 20-pin SOIC package. It accepts a 13.5 MHz crystal reference and uses an on-chip voltage-controlled crystal oscillator with a 0 V to 3 V control input. The control range produces approximately plus or minus 100 ppm output-frequency variation, while the clock-generation section supports CMOS clock outputs up to 27 MHz. A VCXO, or voltage-controlled crystal oscillator, is a crystal oscillator whose frequency can be adjusted by an external voltage. The MK2772-01S combines this oscillator with an analog phase-locked loop and clock synthesis functions in one clock-and-timing IC. This integration supports set-top box designs that require a stable reference frequency plus one or more derived system clocks without implementing a complete discrete oscillator and PLL subsystem. The principal features include a 13.5 MHz crystal input, a 0 V to 3 V VCXO tuning-control range, approximately plus or minus 100 ppm frequency adjustment, CMOS output technology, and operation from a 4.75 V supply as reported in the verified product data. The integrated PLL includes bypass capability, providing a practical path for system bring-up, test, or clock-source fallback. The 20-SOIC package supports conventional surface-mount PCB assembly. Technically, the device uses MicroClock VCXO and analog PLL techniques to derive clocks from an economical crystal. The tuning voltage provides coarse frequency control where the target equipment needs calibration across cable, tuner, or network synchronization requirements. Because the device is identified as obsolete in verified component listings, engineers should avoid new designs and evaluate current-generation clock generators when creating a new board. Typical uses include legacy set-top box main boards, digital video broadcast receivers, and embedded video equipment requiring a stable 13.5 MHz reference with synthesized CMOS clocks. The component may also appear in industrial or communications equipment designed around the same legacy clock architecture, provided its electrical limits, timing margins, and operating-temperature requirements are verified. Design engineers must confirm the complete pinout, crystal load requirement, output enable behavior, control-voltage polarity, and output-drive configuration against the Renesas datasheet before layout or replacement work. Because the component is obsolete, a mechanically similar clock IC is not automatically a safe replacement: its pinout, supply voltage, PLL architecture, tuning range, and output standards must match. This page consolidates the verified manufacturer and distributor information, lifecycle warning, pricing evidence, candidate replacements, comparison parameters, and practical design cautions for engineers evaluating the MK2772-01S or a legacy-board repair.

MK2772-01SLF

MK2772-01SLF VCXO Clock Source | Renesas Electronics

Renesas Electronics MK2772-01SLF is a voltage-controlled crystal oscillator and clock synthesizer designed for set-top clock-source applications. The device operates from a 5 V supply, accepts a 13.5 MHz crystal input, and uses an analog phase-locked loop to generate multiple output clocks. It is packaged in a 20-pin SOIC and includes an external voltage-control input capable of varying the output clocks by +100 ppm. The -01SLF ordering code identifies the lead-free, 20-pin SOIC configuration used for surface-mount production. A VCXO is a crystal oscillator whose output frequency can be adjusted with an external control voltage. The MK2772-01SLF combines that tuning mechanism with clock synthesis, placing it in the clock generator and timing IC hierarchy. This allows a system to correct clock frequency against a reference or implement fine phase and frequency adjustments without replacing the crystal. The device is intended primarily for set-top boxes and other systems requiring a controlled low-jitter clock source. The main functional characteristics include 5 V operation, a 13.5 MHz crystal reference, output-frequency control through a 0 V to 3 V input, and a tuning range of +100 ppm. Its on-chip VCXO and analog PLL techniques allow multiple clock outputs to be produced from one external crystal. The 20-pin SOIC package also provides enough pins for supply connections, control signals, crystal interfaces, and clock outputs. The control architecture supports external frequency adjustment without requiring a separate high-resolution digital synthesizer. A control voltage applied to the VCXO input changes the generated clock relationship by up to +100 ppm, making the circuit useful in phase-aligned receiver, transmitter, or timing systems. The manufacturer datasheet also discusses termination requirements for each clock output and recommends placing the crystal as close as practical to the device to reduce sensitivity to unwanted capacitance and signal degradation. Typical uses include set-top box master clocks, digital television equipment, cable distribution systems, and communication equipment that requires frequency trimming. It can also support clock-generation subsystems in industrial and embedded products when the designer requires analog voltage-based tuning instead of a programmable digital PLL. The 5 V supply and 20-pin SOIC make it particularly suitable for established boards designed around conventional mixed-signal clock devices. A key implementation consideration is power bypassing. The manufacturer datasheet states that at least one 0.1 uF capacitor should be connected between VDD on pin 15 and ground, and the capacitor should be positioned as close to the device as practical. Output termination resistors should also be placed near the relevant clock outputs, while the external crystal connection should be kept short to minimize parasitic capacitance and preserve clock stability. This product summary combines the electrical characteristics, package information, sourcing guidance, and practical implementation notes needed to evaluate the MK2772-01SLF. It also distinguishes verified functions from application guidance, helping engineers determine whether the device fits a set-top clock architecture or whether a different clock-generator family is required.

The verified listing identifies the K30 family as an LCD and mixed-signal MCU, while the related NXP product page identifies the K30 100 MHz segment LCD MCUs as Cortex-M4 devices with advanced analog integration and serial communication. A microcontroller, or MCU, is a semiconductor that integrates a processor core, program memory, data memory, peripherals, and interface logic into one device. The K30 series sits within the broader MCU hierarchy alongside 8-bit, 16-bit, and 32-bit controllers. Its 32-bit Cortex-M4 architecture, 512 KB program storage, and 100 MHz clock position it for embedded control, human-interface, communications, analog monitoring, and display-oriented systems. The verified information identifies the package as 144-LQFP and the programming interface as SWD and JTAG. It also associates the device with Ethernet, USB 2.0, a segment LCD controller, and a 16-bit ADC. These capabilities make it appropriate for connected industrial controls, data acquisition modules, medical and test instruments, operator panels, and embedded gateways. The available source material does not verify the exact ADC resolution, LCD segment count, SRAM capacity, supply range, or peripheral pin assignments, so those details must be confirmed in the manufacturer datasheet before design release. The target suffix contains the “7” after 512, distinguishing it from the related MK30DN512ZVLQ10 listing. Because the supplied search data does not formally establish that the two MPNs are pin-compatible, engineers should not substitute one for the other without checking the official K30 ordering information, pin multiplexing tables, electrical limits, and exposed programming pins. A practical design begins by assigning every LQFP ball to power, ground, reset, clock, programming, communications, analog, and LCD functions according to the manufacturer datasheet. Route sensitive analog inputs away from switching nodes, provide clean references and bypass capacitors, and verify signal levels against the exact device variant. Firmware must also use the matching K30 memory map, startup code, clock configuration, and peripheral drivers. This page consolidates verified distributor inventory, the official NXP family overview, package information, and engineering cautions that are not available from a raw distributor listing alone. It intentionally distinguishes verified facts from data that still requires confirmation, reducing the risk of an invalid drop-in substitution or incomplete production design.
