MK2705S Übersicht
A clock synthesizer is a timing IC that generates or distributes a controlled clock signal used to synchronize digital circuits. In the hierarchy of electronic components, the MK2705S belongs to the clock and timing category, then to clock generators and frequency synthesizers, and ultimately to integrated timing semiconductors. Its purpose is to provide a stable timing reference for audio sampling, MPEG-related equipment, and other clock-sensitive systems.
The verified listing identifies PLL operation, one output, a 1:1 input-to-output ratio, and a primary purpose of audio and MPEG. The same listing describes support for clock and crystal inputs, while the distributor record specifies 8-SOIC packaging and a 24.576 MHz frequency. These details support applications requiring a defined audio-clock source, although operating voltage, supply current, jitter, temperature range, and exact electrical limits require confirmation from the manufacturer datasheet.
The MK2705 architecture is intended to separate timing generation from the surrounding digital signal chain. Using a dedicated clock synthesizer can simplify clock distribution and help ensure that multiple downstream circuits receive the intended frequency relationship. In an MPEG or audio system, the relevant clock must match the sampling architecture, so the selected frequency and input configuration should be checked against the system specification before layout release.
Typical uses include MPEG audio equipment, digital audio sampling systems, clock recovery modules, and embedded audio interfaces that require a stable reference clock. The 8-SOIC package is suitable for conventional surface-mount PCB assembly, provided the recommended footprint, decoupling, crystal or clock-input layout, and output-routing guidance in the manufacturer datasheet are followed.
The principal design consideration is exact frequency compatibility. MK2705S should be selected only where the required clock is 24.576 MHz or where the supported synthesis mode matches the intended input. Verify pin names, input frequency limits, output jitter, supply voltage, and package tolerances against the current Renesas documentation before production.
This page consolidates distributor listings, the available datasheet references, package information, and application guidance for MK2705S. It also distinguishes verified facts from parameters that still require datasheet confirmation, helping engineers avoid unsupported assumptions during component selection.

MPEG Audio Sampling Clock
The MK2705S is a direct fit for MPEG audio systems that need synchronous clock generation from a defined reference. Its verified primary purpose is Audio, MPEG, and the device is listed as a PLL-based clock/frequency synthesizer with one clock output. Place it where the audio subsystem requires a stable sampling reference derived from the MPEG clocking architecture. The 24.576 MHz listing is relevant when that is the system’s required clock, but the input ratio, supply limits, jitter, and startup behavior must be confirmed from the Renesas datasheet before layout and firmware decisions are finalized.
Empfohlen
Digital Audio Interface Clocking
Use the MK2705S where a digital audio interface needs a dedicated frequency source rather than relying on a distributed system clock. Its one-output architecture is appropriate for a single timing branch, while the listed 1:1 input-to-output relationship can simplify designs where the reference and generated clock relationship is unchanged. The part’s PLL feature provides a timing-conversion function, but actual lock behavior, jitter, input-frequency limits, and output-drive capability require the manufacturer datasheet. Validate the clock topology against the audio converter’s required sampling and modulation clocks.
Empfohlen
Standalone Crystal Clock Source
The MK2705S can be configured as a standalone clock source with a 27 MHz crystal, according to the verified device description. This application is useful when the design needs a controlled local reference instead of routing a master clock through the entire system. Select the crystal and load network from the manufacturer reference design, and provide the required local decoupling and short clock traces. Because the supplied data does not state crystal load capacitance, startup time, drive level, or output jitter, those details must be obtained from the current datasheet before release.
Empfohlen
Audio Equipment Control Reference
The MK2705S can support audio equipment that requires an organized timing reference across digital processing and conversion sections. Its audio/MPEG classification and single clock output make it relevant to compact systems where one generated clock must feed a defined downstream block. The design benefit is timing centralization, but the clock must remain within the supported frequency and electrical limits of every receiving device. Route the output as a controlled clock signal, observe the datasheet’s grounding and decoupling recommendations, and verify that startup does not violate downstream sequencing requirements.
Empfohlen
Synchronous MPEG Processing System
The MK2705S is described as supporting synchronous clock generation for audio sampling rates derived from an MPEG stream. In an MPEG processing system, the clock generator can provide a dedicated timing source to a selected audio-processing path, reducing dependence on a system-wide clock distribution arrangement. The verified records do not state the full synthesis ratio table, lock time, or jitter, so the device should be adopted only after checking those specifications. Confirm the input clock source and ensure that the generated 24.576 MHz output matches the receiving MPEG/audio subsystem requirements.
Empfohlen
Embedded Audio Subsystem Timing
In an embedded audio subsystem, the MK2705S can serve as a focused clock-generation IC for a converter or digital audio path. The 8-SOIC package supports surface-mount assembly, while the one-output topology keeps the timing path explicit. However, the supplied information does not establish compatibility with any particular microcontroller or processor, and no Site MPN is confirmed as a functional companion for this clock part. Validate the required frequency, input source, supply voltage, and package footprint against the host device and the complete Renesas datasheet before selecting it for a new design.
Empfohlen
Clock-Distribution Test Fixture
The MK2705S can be evaluated in a small clock-generation or signal-integrity test fixture before integration into a finished audio product. Its 24.576 MHz nominal output and documented audio/MPEG purpose make it convenient for checking clock routing, output behavior, and downstream timing assumptions. The test fixture should use a controlled reference source and measure the output with appropriate equipment rather than assuming that a distributor frequency label describes every operating condition. Since supply voltage, jitter, output waveform, and pin functions are not supplied, use the manufacturer datasheet for the final test setup.

Wichtigste Unterscheidungsmerkmale
- Audio/MPEG clock-generation positioning (vs. MK2705SLF)
- Verified PLL and single-output architecture (vs. MK2705SLFTR)
- Named 24.576 MHz operating point (vs. K2705)
Designhinweise
Design the MK2705S supply rail from the exact operating-voltage and current limits in the current Renesas datasheet. Place the required bypass capacitors at the power and ground pins using the manufacturer reference layout, and keep the clock-generator return path close to the device. Because the supplied data does not state supply voltage or current, do not infer the rail from the 24.576 MHz frequency or from the distributor category.
Use the exact 8-SOIC footprint and pin numbering from the MK2705S datasheet. Keep the crystal or clock-input traces short, preserve the recommended ground return, and route the 24.576 MHz output away from sensitive analog and high-speed digital nodes where practical. Generic SOIC drawings are not sufficient because the supplied snippets do not identify individual MK2705S pins.
Treat the generated clock as a timing signal with controlled edge behavior and loading. Confirm the output waveform, load, jitter, and maximum downstream capacitance from the manufacturer datasheet before adding fan-out or long traces. If the clock feeds an audio converter or processor, verify that the receiving device accepts the MK2705S output amplitude and frequency rather than assuming compatibility from the nominal 24.576 MHz label.
Do not select a substitute from the MK2705 name alone. The cross-reference search results identify family-related markings but do not prove identical pinout, package, supply requirements, frequency behavior, or timing performance. Before using any alternative, compare the manufacturer pin table, 8-SOIC footprint, input configuration, PLL behavior, output specification, and lifecycle status. Treat the listed alternatives as leads for verification, not automatically approved drop-ins.
Compliance-Informationen
Compliance information is not present in the supplied verified data. Do not infer RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 status from the manufacturer name or distributor listing.
