MK2703STR 概述
A PLL clock synthesizer is a clock-generation and timing component that compares an input reference with an internal feedback signal, locks a phase-locked loop, and produces one or more stable output frequencies. In the broader electronics hierarchy, the MK2703STR belongs to the clock and timing IC category and supports systems where predictable audio-frequency generation is required. Its bypass function is useful when the system needs a direct clock path during specific operating conditions.
The verified listing identifies the MK2703STR as a low-cost, low-jitter, high-performance PLL clock synthesizer intended to replace discrete oscillator and PLL circuits in set-top box and multimedia systems. The specified maximum frequency is 27MHz, and the listed input/output ratio is 2:2. The CMOS output supports integration with digital audio, consumer multimedia, and related embedded systems where a standardized clock source is advantageous.
The 8-SOIC package is suitable for conventional surface-mount PCB assembly and provides a compact implementation for consumer equipment. Because the supplied verified data does not state the complete electrical limits, pin names, supply voltage, jitter value, or crystal-load details, those parameters should be confirmed in the Renesas MK2703 datasheet before schematic capture or production release.
Typical uses include digital audio clocking, set-top box clock generation, multimedia system timing, and other consumer electronics requiring a low-jitter PLL-based reference. In these applications, the device can simplify clock distribution by consolidating oscillator and feedback functions into one timing IC, although the final bill of materials still depends on the required frequency, output format, and system clock tree.
Designers should place the IC and its decoupling connections according to the manufacturer layout guidance, preserve the recommended crystal or reference network, and verify output jitter and lock behavior over the intended supply and temperature range. This page summarizes verified distributor and manufacturer references while clearly separating unavailable parameters from confirmed facts.

典型应用
MK2703STR 适用于 6 应用s: Set-Top Box Clock Generation, Multimedia System Timing, Digital Audio Clock Reference, Consumer Audio Interface Timing, Compact Embedded Clock Circuit, Low-Jitter Reference Architecture.
Set-Top Box Clock Generation
The Renesas Electronics MK2703STR is a strong candidate for set-top box clock-generation blocks because it is identified as a PLL audio clock synthesizer with a 27MHz maximum frequency, PLL bypass, CMOS output, and an 8-SOIC package. It can be placed in the system timing section to provide a stable reference for audio and multimedia processing. The PLL architecture allows the design to use a controlled feedback loop, while bypass supports alternate clock-path requirements. Before final selection, engineers should verify the required reference frequency, supply voltage, jitter target, and downstream clock-tree loading in the Renesas datasheet.
推荐
Multimedia System Timing
The MK2703STR fits consideration for multimedia systems that need a dedicated low-jitter PLL clock source. Its verified 27MHz maximum frequency, PLL bypass capability, CMOS output, and single-circuit implementation make it suitable for compact timing architectures. The device can help replace separate oscillator and PLL functions, reducing the number of discrete clock components in suitable designs. The design benefit depends on matching the device's actual reference requirements and output frequency to the multimedia subsystem. Confirm jitter, supply range, and pin-level timing constraints before integrating it into a new board.
推荐
Digital Audio Clock Reference
For digital audio designs, the MK2703STR can serve as a PLL-based clock synthesizer when the system requires a stable CMOS timing reference. The verified specification identifies clock or crystal input, PLL bypass, and a 2:2 input-to-output ratio, providing concrete starting points for architecture planning. Its low-jitter positioning makes it relevant to audio-clock applications where timing quality affects the downstream converter or interface. The engineer must still confirm the exact jitter value, supply voltage, load capacitance, and operating-temperature range in the manufacturer datasheet before setting the audio clock architecture.
推荐
Consumer Audio Interface Timing
The MK2703STR is appropriate for evaluation in consumer audio interfaces where a compact PLL clock synthesizer can simplify clock generation. The 8-SOIC package supports conventional surface-mount assembly, while the CMOS output can feed compatible digital timing stages. Its bypass function may help the design support a direct clock path when required by the system architecture. The principal design checks are reference stability, PLL lock behavior, output loading, and EMI-sensitive routing around the clock lines. Confirm those details and the complete pinout from the official Renesas document.
推荐
Compact Embedded Clock Circuit
The MK2703STR can be considered in compact embedded products where a single PLL timing circuit is preferable to a larger discrete oscillator and feedback network. Its verified one-circuit implementation, 27MHz maximum frequency, PLL bypass, and 8-SOIC package provide a useful feature set for space-constrained consumer electronics. The component is most suitable when the system requires a CMOS clock and the design can meet the manufacturer's reference-network and layout requirements. Because the supplied data does not state input sensitivity, jitter, or supply limits, engineers should avoid committing the part without reviewing the complete Renesas datasheet.
推荐
Low-Jitter Reference Architecture
The MK2703STR is marketed in verified distributor descriptions as a low-cost, low-jitter, high-performance PLL clock synthesizer. That positioning makes it a candidate for reference architectures where the oscillator and feedback functions can be consolidated into one IC. The confirmed 27MHz ceiling and bypass capability can simplify planning for selectable clock behavior, while CMOS output supports digital integration. A final design decision requires comparing the actual jitter and lock specifications against the system budget, along with verifying output loading, supply voltage, and temperature performance from the manufacturer datasheet.

- PLL bypass capability （对比 MK2703BSLFTR)
设计说明
Use the manufacturer layout guidance for the 8-SOIC footprint and route the reference and clock nets as short as practical. Place required decoupling close to the device power pins, preserve a continuous ground reference, and avoid routing high-current switching paths beneath clock nodes. The supplied verified material confirms the package family but does not provide a complete pinout or recommended land pattern, so obtain those from the Renesas MK2703 datasheet before layout release.
Confirm the MK2703STR supply-voltage range and decoupling requirements directly from the official datasheet before adding bulk or local capacitors. A clock synthesizer may be sensitive to reference amplitude, supply noise, and startup behavior even when its output is CMOS. Do not infer capacitor values or voltage limits from the 27MHz frequency specification; use the manufacturer's recommended values and validate supply ripple at the IC.
Treat the reference input, PLL feedback, and CMOS output as timing-sensitive nets. Keep the oscillator or crystal network close to the device, maintain the recommended grounding, and verify output rise/fall behavior and load capacitance in the target design. Because the supplied data does not state exact jitter, input sensitivity, or load limits, measure clock quality in the final board rather than assuming performance from the family description.
合规信息
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields require confirmation from the manufacturer product documentation or current compliance records.
