MK2704S Visão geral
A PLL clock synthesizer multiplies or organizes a reference clock into a stable operating or audio sampling clock. In the signal path, it belongs to clock and timing ICs, where its role is to generate predictable digital timing from a crystal or external reference. The available ratio of 1:2 indicates that this device family is intended for a defined clock-generation relationship rather than general-purpose fractional-N synthesis.
Key verified features include PLL operation with bypass, clock or crystal input, one clock circuit, and a CMOS output. The bypass path is useful during startup, test, or mode transitions, while the PLL path supports synthesized clock generation. The 36.864MHz maximum frequency makes the device applicable to multimedia timing systems operating around common digital audio-related clock domains, subject to the complete manufacturer datasheet limits.
The MK2704S uses a single 8-pin SOIC package according to the available distributor records. The package supports conventional surface-mount assembly and can simplify board replacement compared with discrete oscillator-plus-divider assemblies. Its architecture is intended to replace separate oscillator and PLL circuits in set-top box and multimedia equipment, reducing board count while centralizing clock generation.
Typical uses include set-top box clock generation, multimedia system timing, digital audio interfaces, and other embedded systems requiring a CMOS clock with bypass control. When designing around the device, verify crystal start-up requirements, output loading, supply voltage, and all operating conditions against the manufacturer datasheet. Because the supplied evidence is distributor-oriented and does not include a complete official parametric table, unverified values are not inferred.
This product page combines verified source snippets, application guidance, source links, and engineering caveats rather than inventing electrical ratings. It distinguishes known specifications from fields that require confirmation in the manufacturer datasheet, helping engineers identify the MK2704S quickly while avoiding unsupported claims.

Aplicações típicas
MK2704S é adequado para 6 aplicaçãos: Set-Top Box Clock Generation, Multimedia System Timing, Digital Audio Interface Clocking, Consumer Audio Equipment, Embedded Multimedia Control Platform, Digital Video Peripheral Timing.
Set-Top Box Clock Generation
The MK2704S is a compact clock-generation option for set-top boxes because the verified description positions it as a low-cost PLL synthesizer intended to replace separate oscillator and PLL circuits. Its 36.864MHz maximum frequency, clock-or-crystal input, CMOS output, and PLL bypass make it a plausible fit for digital video, audio, and control-clock organization. The designer should confirm the required frequency range, lock behavior, supply voltage, and output loading in the manufacturer datasheet before finalizing the clock tree.
Recomendado
Multimedia System Timing
For multimedia equipment, the MK2704S can centralize a reference-derived clock path in an 8-pin SOIC package. The verified PLL and bypass functions allow an implementation to switch between synthesized and bypassed clock operation, while the CMOS output can feed compatible digital logic. Its suitability depends on the actual sample rate, bus clock, video timing, and jitter requirements; those application-specific values are not included in the supplied source snippets and must be verified.
Recomendado
Digital Audio Interface Clocking
The MK2704S is identified as a PLL audio clock synthesizer and therefore belongs naturally in digital audio clock-distribution logic. The 1:2 ratio and 36.864MHz maximum frequency may align with selected multimedia clock domains, but the supplied evidence does not establish whether the part meets a particular I2S, S/PDIF, or DAC master-clock requirement. Use it only after checking jitter, edge-rate, supply, and input-reference specifications against the target audio interface.
Recomendado
Consumer Audio Equipment
The MK2704S can serve as a clock synthesizer in consumer audio equipment where a compact PLL and bypass-capable clock source is useful. The verified CMOS output and single 8-pin SOIC package provide a straightforward integration path, while the low-cost positioning suits cost-sensitive multimedia products. The design must still account for crystal selection, startup time, bypass-control sequencing, output capacitance, and the difference between nominal maximum frequency and guaranteed operating limits.
Recomendado
Embedded Multimedia Control Platform
In an embedded multimedia control platform, the MK2704S can provide a dedicated clock synthesizer beside a processor or interface controller. Clock-or-crystal input supports integration with an existing reference source, and PLL bypass can aid initialization or alternate operating modes. The component should be placed according to the complete manufacturer layout guidance; the supplied data does not provide grounding, decoupling, or loop-filter recommendations, so those details cannot be prescribed here.
Recomendado
Digital Video Peripheral Timing
The MK2704S may be evaluated for digital video peripheral timing where the system needs a CMOS clock derived from a crystal or external clock. Its PLL architecture and bypass mode can simplify clock-domain organization in compact consumer electronics, while the 8-pin SOIC package is convenient for conventional surface-mount assembly. Actual video applications require exact pixel-clock, horizontal-frequency, and synchronization requirements; these are not supplied, so the part should be treated as a design candidate rather than a confirmed solution.

Notas de projeto
Do not treat the 36.864MHz maximum frequency as proof that every required frequency is supported. The supplied snippets do not provide guaranteed input/output ranges, PLL ratios, lock-time limits, or jitter values. Verify those specifications and the complete pinout in the manufacturer datasheet before laying out a crystal, bypass-control circuit, or downstream clock buffer.
Route the clock input, PLL output, and bypass-related signals as short, controlled-impedance paths where applicable. Keep the crystal and clock input away from noisy switching nodes and provide a clean return path. Because the supplied data does not include recommended land patterns, decoupling values, or loop-filter layout, use the official application guidance before finalizing the PCB footprint and grounding strategy.
Confirm the device's supply-voltage limits, input and clock-output voltage levels, and power-consumption limits from the complete datasheet before connecting it to a system rail. The supplied search snippet mentions a 7V reference in a generic electrical-specification excerpt but does not provide a verified operating range for this exact record. Do not use that isolated value as a design rating without manufacturer confirmation.
Informações de conformidade
The supplied verified data contains product descriptions, distributor listings, and datasheet links but does not provide a current manufacturer declaration for RoHS, REACH, lead-free status, halogen-free status, conflict minerals, or automotive qualification. Verify current compliance documents before production release.
