MK2732-06G - 54 MHz PLL Clock Synthesizer | Renesas
MPN: MK2732-06G ✓ ActiveMK2732-06G Overview
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.

Typical Applications
MK2732-06G is suitable for 6 applications: xDSL Chipset Clocking, MPEG-2 Decoder Timing, Communication Equipment Clock Tree, Crystal-Referenced Timing Module, Network Interface Timing, Multimedia Processing Platform.
xDSL Chipset Clocking
The MK2732-06G fits xDSL chipset clocking because it combines a crystal reference, an adjustable VCXO, PLL bypass, and a CMOS output in one 16-TSSOP device. The verified maximum frequency is 54 MHz, while the 0 V to 3 V tuning input provides a documented 200 ppm pull range for limited output-frequency adjustment. This integration can replace separate discrete VCXO and multiplier stages, reducing board area and component count. The design must still account for crystal startup, reference-loop layout, control-voltage noise, and supply bypassing before confirming the clock meets the chipset's jitter and accuracy limits.
MPEG-2 Decoder Timing
The MK2732-06G is suitable for an MPEG-2 decoder when the system needs a local crystal-referenced CMOS clock with controlled frequency adjustment. Its PLL and bypass functions provide clock-generation flexibility, and the 54 MHz maximum frequency covers the operating range identified in the verified device data. Integrating the VCXO, PLL, and multiplier into a 16-TSSOP package can simplify clock-tree construction compared with separate oscillator and multiplier components. For multimedia equipment, keep the crystal loop short and isolate the VCXO tuning line from noisy signals so that switching or video-processing activity does not modulate the delivered clock.
Communication Equipment Clock Tree
The MK2732-06G can provide a local, adjustable clock source in communication equipment that requires a crystal oscillator rather than an off-chip reference. Its single-clock architecture, 1:3 input-to-output ratio, PLL bypass option, and 54 MHz maximum output frequency suit clock-generation blocks that need modest multiplication or tuning. The 16-pin TSSOP package also supports conventional surface-mount PCB assembly. Actual deployment depends on confirming the decoder's supply-voltage requirement, output waveform, frequency range, jitter, and startup behavior from the Renesas datasheet, none of which were quantified in the supplied search data.
Crystal-Referenced Timing Module
The MK2732-06G is appropriate for a compact crystal-referenced timing module requiring an on-board VCXO and PLL rather than a simple fixed-frequency oscillator. Its 0 V to 3 V tuning range and 200 ppm documented pull range allow limited calibration of the output clock, while PLL bypass provides an additional operating path. Integration of the oscillator, multiplier, and PLL can lower assembly complexity compared with a discrete implementation. Because the exact jitter, output duty-cycle, and reference requirements are unavailable in the verified data, they must be checked against the manufacturer datasheet before the module is released.
Network Interface Timing
The MK2732-06G can support a network interface timing block that requires a locally generated CMOS clock and limited frequency adjustment. The verified 54 MHz ceiling and 1:3 ratio make it relevant to designs using a lower-frequency crystal reference with clock multiplication, while the VCXO permits calibration without replacing the crystal. The integrated PLL, bypass mode, and surface-mount TSSOP-16 package are useful for compact networking equipment. Board implementation should prioritize a clean crystal reference, short clock routes, proper ground return, and isolated tuning-voltage routing to avoid coupling processor or switching-regulator noise into the oscillator.
Multimedia Processing Platform
The MK2732-06G can serve multimedia platforms requiring a stable crystal-derived clock alongside adjustable phase or frequency control. Its PLL-based architecture, VCXO tuning capability, CMOS output, and 54 MHz maximum frequency are relevant to MPEG-2 decoder and related signal-processing equipment. Consolidating the oscillator and multiplier functions can simplify the clock tree, although PLL and bypass settings still need to match the processor's timing requirements. Because detailed timing, jitter, supply, and pin data are absent from the verified excerpts, engineers should use the official Renesas document as the controlling source before schematic release.

- Single-surface-mount clock solution (vs Multiple discrete timing components)
Design Notes
Keep the crystal, oscillator loop, and clock output routing compact and away from switching nodes. The supplied data confirms that the MK2732-06G is a crystal-input VCXO and PLL, but it does not provide the recommended land pattern. Follow the Renesas datasheet reference layout exactly, provide a clean return path, and avoid routing the VCXO tuning trace parallel to high-speed digital or power signals.
Treat the 0 V to 3 V VCXO control voltage as a sensitive analog input. The documented tuning range produces a 200 ppm pull capability, so clock-frequency modulation can result from ripple or noise on that control path. Filter the tuning source where appropriate, connect it close to the relevant device pin according to the manufacturer layout, and test the system for output-frequency variation when nearby digital or switching circuitry is active.
Do not select a clock replacement from the 16-TSSOP package or 54 MHz headline rating alone. A valid substitution must also preserve the crystal interface, 1:3 ratio, PLL and bypass behavior, 0 V to 3 V VCXO control range, supply requirements, output waveform, and timing performance. The supplied cross-reference data supports MK2732-06GLF as functionally compatible, but the complete electrical and pin-level review must still be completed before substitution.
Use the manufacturer datasheet to determine the MK2732-06G's supported supply range and decoupling configuration because neither value appears in the supplied verified excerpts. Place the required bypass capacitors adjacent to their associated pins and maintain a low-impedance ground connection. Clock generators are often treated as simple digital loads, but an unstable reference or supply can increase phase noise or alter startup behavior.
Compliance Information
The supplied verified results do not explicitly state compliance for the target MK2732-06G. A lead-free statement associated with MK2732-06GLF was not transferred to the target MPN.
