MK2703S - 27MHz PLL Clock Synthesizer | Renesas
MPN: MK2703S ✓ Hoạt độngMK2703S Tóm tắt
A PLL clock synthesizer is a timing IC that uses a phase-locked loop to generate or distribute a stable reference clock for digital and multimedia systems. In the broader electronics hierarchy, the MK2703S belongs to clock and timing integrated circuits, alongside clock generators, frequency dividers, PLL multipliers, and clock buffers. Its purpose is to replace discrete oscillator and PLL circuitry with a compact integrated solution.
The verified product data identifies the MK2703S as a low-cost, low-jitter, high-performance PLL clock synthesizer for set-top boxes and multimedia equipment. Its specified 27MHz operating frequency provides a centralized timing reference for system logic, while the 3.13V to 5.5V supply range accommodates common embedded and consumer electronics rails. The 8-SOIC package supports conventional surface-mount assembly and reduces board area compared with discrete oscillator networks.
The part is offered in tube packaging according to the verified distributor listing, and distributor records also identify it as a PLL clock synthesizer IC with a 1-output configuration. Exact jitter, phase noise, lock-time, output-drive, and reference-input details were not included in the supplied web excerpts and therefore require confirmation from the manufacturer datasheet before production release. Those unspecified values are important when evaluating a replacement or a new board design.
Typical uses include set-top box timing, multimedia processor clocks, digital media modules, and compact consumer systems requiring a single synthesized clock. The MK2703S can replace a discrete oscillator and PLL implementation, but the reference clock source, loop-filter network, output load, and decoupling requirements must follow the manufacturer application guidance. The verified source describes the device as intended to replace oscillators and PLL circuits, while the operating conditions and package details define the core procurement and integration constraints.
For a new design, begin with the official Renesas MK27033 datasheet and verify the complete pinout, recommended reference configuration, and electrical limits before layout. Distributor search data confirms the 27MHz device, SOIC-8 package, and supply range, but it does not provide enough detail to reconstruct the full application circuit. Pricing, stock, and lifecycle status should also be checked against current distributor records at the time of purchase.
This product summary combines verified distributor attributes with the manufacturer datasheet resource, while clearly separating known electrical facts from parameters requiring datasheet confirmation. It is useful for initial sourcing, clock-tree architecture review, and identifying whether the MK2703S belongs in a candidate design, but it is not a substitute for the complete manufacturer datasheet.

Ứng dụng tiêu biểu
MK2703S phù hợp cho 6 Áp dụngs: Set-Top Box Timing, Multimedia Processor Clocking, Digital Media Module Timing, Consumer Audio Equipment, Embedded Control Systems, Communication and Interface Timing.
Set-Top Box Timing
The MK2703S is suitable for the central timing reference in a set-top box because the verified product description specifically targets set-top box and multimedia systems and identifies a 27 MHz PLL clock output. Place the IC where the processor and multimedia blocks can receive a stable synthesized reference while the PLL handles frequency multiplication or conditioning. The 3.13 V to 5.5 V supply range supports common embedded rails, but designers must confirm the reference frequency, loop filter, output loading, and startup timing from the Renesas datasheet. Its 8-SOIC package also reduces board area while retaining conventional surface-mount assembly.
Được đề xuất
Multimedia Processor Clocking
Use the MK2703S as a single PLL clock source for multimedia processor and interface logic when the system needs a 27 MHz reference without a discrete oscillator-plus-PLL network. The integrated synthesizer can simplify the clock-generation block and reduce component count, while the one-output configuration keeps the clock distribution requirement focused. The verified data does not specify output-drive strength, jitter, or phase noise, so the clock-tree design must be validated against those missing parameters and the manufacturer recommended circuit. Short traces, a continuous return plane, and proper decoupling are essential at 27 MHz.
Được đề xuất
Digital Media Module Timing
The MK2703S can provide the timing reference for compact digital media modules where an integrated PLL is preferable to separate clock components. Its 27 MHz output matches the verified product classification, and the 3.13 V to 5.5 V range allows operation from common low-voltage digital rails. In a media module, keep the synthesizer close to the clock-consuming logic or distribute the clock through a controlled network to prevent edge degradation. Confirm whether the required system clock is the direct PLL output or a divided derivative, since the supplied excerpts do not define the programmable divider range.
Được đề xuất
Consumer Audio Equipment
The MK2703S is applicable to consumer audio and multimedia equipment when a stable digital timing reference is needed before audio conversion or processing. The low-jitter positioning of the device can help reduce unwanted clock-related modulation, although the exact jitter and phase-noise values are not present in the verified excerpts. Use the PLL output to feed the relevant digital audio interface or processor, and follow the datasheet for bypass, reference, and decoupling requirements. The 8-SOIC package is practical for compact consumer products, while the 3.13 V minimum supply supports integrated audio subsystems operating near 5 V.
Được đề xuất
Embedded Control Systems
The MK2703S can serve as a dedicated clock generator in embedded control systems that require a stable reference separate from an internal oscillator. The verified 27 MHz specification provides a concrete selection point for clocking digital logic, converters, or communication peripherals. Because the device is a PLL synthesizer, the design must provide the correct reference source and feedback network rather than treating it as a simple crystal oscillator. Confirm output format and load capability in the datasheet before connecting sensitive high-speed nodes, and maintain short, well-referenced clock traces to avoid adding avoidable edge noise.
Được đề xuất
Communication and Interface Timing
The MK2703S is potentially suitable for interface-clock conditioning in communication or multimedia equipment where a shared 27 MHz reference can synchronize multiple digital blocks. The one-output configuration makes it most appropriate when downstream buffers or a controlled fan-out network handle distribution. The verified data does not state output impedance, duty-cycle tolerance, or PLL locking behavior, so the buffer and endpoint requirements must be checked before production. Use a continuous ground reference beneath the clock path, minimize stubs, and follow the manufacturer layout guidance to preserve edge quality and prevent the clock from becoming an EMI source.

Ghi chú thiết kế
Place the MK2703S close to the reference clock source and the load it drives, and provide local decoupling exactly as specified by the Renesas application guidance. The verified supply range is 3.13 V to 5.5 V, so confirm that the upstream regulator remains within that range during startup and load transients. Do not infer capacitor values or PLL stability from the distributor listing; use the manufacturer reference circuit because the supplied data does not provide those values.
Route the 27 MHz clock as a short, controlled-impedance trace over a continuous reference plane and avoid unnecessary stubs or test-point discontinuities. Keep the clock path away from switching-power high-current loops and noisy digital return paths. Because the provided excerpts do not specify output drive or edge-rate limits, validate the fan-out, termination, and downstream loading using the official datasheet before increasing board size or clock frequency.
Treat the PLL output as a timing signal rather than a general-purpose power or data line. Check the clock duty cycle, output amplitude, jitter, and phase-noise requirements at every endpoint using the complete manufacturer datasheet. If the clock feeds multiple loads, use the recommended buffer or distribution topology rather than adding arbitrary long branches. An oscilloscope measurement of edge quality and a system-level clock-margin test should precede production release.
Thông tin tuân thủ
The supplied verified web results do not state environmental or automotive compliance claims for MK2703S. Compliance should be confirmed from the current Renesas product documentation and supplier declarations.
