MK2732-06GLF - 5V VCXO-PLL Clock Synthesizer | Renesas
MPN： MK2732-06GLF ✓ 啟用中MK2732-06GLF 概覽
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. It emphasizes engineering suitability rather than assuming that a related suffix is automatically pin-compatible, and it directs buyers to XAIPART's Request a Quote form for current commercial terms.

典型應用
MK2732-06GLF 適用於 6 應用s: Communication Clock Recovery, Frequency Conversion and Multiplication, Precision Test and Measurement, Industrial Control and Data Acquisition, RF and Communication Equipment, Low-Cost Oscillator Replacement.
Communication Clock Recovery
The MK2732-06GLF fits communication clock-recovery designs that need a controllable reference derived from a crystal. Its VCXO accepts a 0 V to 3 V tuning voltage and varies the output clocks by ±100 ppm, allowing a loop or calibration system to compensate for small frequency errors. Operating from 4.75 V to 5.25 V and using CMOS-compatible interfaces simplifies integration with digital timing logic. The integrated PLL and multiplier functions reduce the component count compared with a discrete VCXO followed by a separate frequency multiplier. Confirm the configured output frequency, jitter, and loop stability against the communication link's timing budget before production.
Frequency Conversion and Multiplication
The MK2732-06GLF is appropriate when a system must multiply or convert a reference clock rather than supply that frequency directly to every circuit. Its PLL-based clock synthesizer architecture provides an integrated path from the crystal reference to derived outputs, while the VCXO permits fine adjustment over a ±100 ppm range. This is useful in instrumentation and embedded systems where multiple subsystems require related but not identical timing signals. Use the manufacturer's frequency-planning information to establish valid divider and output combinations. Pay particular attention to reference-noise transfer because jitter or phase noise at the source can affect every derived clock.
Precision Test and Measurement
The MK2732-06GLF can support test and measurement equipment that requires a stable, adjustable clock close to the instrument's acquisition or conversion circuitry. The VCXO tuning input permits calibration of small frequency offsets, while the PLL architecture generates derived clock outputs from a common reference. Its 4.75 V to 5.25 V supply range and 16-pin TSSOP package support compact implementation on a densely populated instrument board. For sensitive measurements, keep the reference oscillator and control path isolated from switching converters and relay-drive circuits, and verify output jitter and phase noise under the final configuration.
Industrial Control and Data Acquisition
Industrial controllers and data-acquisition systems often need a local timing reference that remains independent of their main processor clock. The MK2732-06GLF combines a VCXO, PLL, and multiplier in one 16-pin TSSOP device, allowing a crystal reference to feed multiple related timing domains. Its ±100 ppm VCXO adjustment range can correct small crystal or system errors, while CMOS-compatible outputs suit digital logic. Place the device away from motors, relays, and high-current switching stages, and use controlled-ground layout to prevent reference noise from appearing as timing jitter. Validate the complete timing tree over its required temperature range.
RF and Communication Equipment
The MK2732-06GLF can provide a tunable, low-noise clock source for RF and communication equipment requiring disciplined frequency distribution. The VCXO adjustment range of ±100 ppm supports fine reference correction, while PLL synthesis allows clock outputs to be derived from a common crystal. Integrating these functions reduces board area compared with separate oscillator and multiplier components. Place the oscillator section away from RF power stages and switching supplies, and route the control voltage through a quiet path because noise on the VCXO input can modulate phase noise. Confirm the required output frequency and spectral characteristics in the final reference configuration.
Low-Cost Oscillator Replacement
The MK2732-06GLF suits designs that would otherwise combine a discrete VCXO, frequency multiplier, and associated routing. Renesas positions the device as a low-cost, low-jitter, high-performance integrated alternative for such assemblies. Its lead-free 16-pin TSSOP package supports automated assembly, and the 4.75 V to 5.25 V operating range is convenient for conventional digital rails. The main design trade-off is that the crystal, loop, and output configuration must be coordinated with the manufacturer requirements. Review startup, output-enable, and load conditions carefully before replacing a proven discrete implementation.

主要差異化特點

- Adjustable clock correction (對比MK2732-06G)
- Compact integrated alternative to discrete timing assemblies (對比MK2732-06G)
設計說明
Follow the Renesas recommended layout and place the supply bypass capacitor immediately between the MK2732-06GLF supply and ground pins. Keep crystal, VCXO-control, feedback, and clock traces short, provide a continuous ground reference beneath the device where layout rules permit, and avoid routing these nets beside switching-converter power paths. The 16-pin TSSOP land pattern must match the manufacturer's package drawing.
Treat the VCXO control voltage as a noise-sensitive reference signal. The control input can vary the output by ±100 ppm, so any noise coupled onto it may become frequency or phase modulation at the synthesized outputs. Use a filtered, low-noise control source, keep the trace short, and provide a quiet return path. Validate the final circuit with phase-noise or jitter measurement because specifications can vary with output configuration.
Do not select a family member solely because its suffix resembles the MK2732-06GLF. Confirm the 16-pin TSSOP package, pin functions, temperature grade, reference frequency, output configuration, and lead-free ordering status against the manufacturer ordering table. The 0 V to 3 V VCXO control input is not the device's 4.75 V to 5.25 V main supply, and confusing the two can lead to incorrect circuit protection or an unstable tuning network.
