MK2302S-01 Visão geral
A zero-delay buffer is a clock-management device intended to reproduce an input clock at one or more outputs while controlling propagation delay and phase relationship. The MK2302S-01 uses PLL techniques to distribute a clock signal and can therefore be useful in systems where the source clock must be isolated or regenerated before reaching multiple sequential or communications circuits. In the system hierarchy, it belongs to the clock and timing IC family rather than a general-purpose logic IC.
Verified device characteristics include a maximum frequency of 168 MHz, one clock circuit, a CMOS output, and a 3.15 V to 3.45 V supply range. The manufacturer and distributor search results identify the part as a multiplier and zero-delay buffer. Additional timing, output-current, jitter, temperature, and package-dimension values were not supplied in the verified data and therefore require confirmation from the manufacturer datasheet before final design release.
Typical uses include clock distribution for communications equipment, digital logic systems, embedded processors, interface controllers, and test equipment. The integrated PLL architecture is relevant when the circuit needs a regenerated clock rather than a passive fanout buffer. Designers should compare both source and destination clock requirements, verify the supported output configuration, and check propagation-delay behavior across temperature and supply voltage before using the device as a drop-in element in an existing design.
The most important layout consideration is short, controlled clock routing. Keep the input and output paths away from noisy switching nodes, use a continuous ground reference, and terminate unused outputs according to the manufacturer recommendations. The available search results do not provide a verified pricing schedule, complete pin mapping, lifecycle statement, or detailed electrical limits; those fields remain explicitly marked for data acquisition rather than being inferred.
This page combines the verified Renesas and distributor classifications with practical clock-distribution guidance, package information, sourcing references, and an explicit data-completeness assessment. It is intended to support initial component selection while distinguishing confirmed specifications from parameters that must still be checked in the official datasheet.

Aplicações típicas
MK2302S-01 é adequado para 6 aplicaçãos: Communications Clock Distribution, Embedded Processor Clocking, Digital Logic Clock Fanout, Test and Measurement Equipment, RF and High-Speed Interface Support, Industrial Control and Data Acquisition.
Communications Clock Distribution
The MK2302S-01 is suited to communications systems that need a regenerated or multiplied clock instead of a simple passive fanout path. Its verified 168 MHz maximum frequency, 3.15 V to 3.45 V supply range, and PLL-based architecture make it relevant to interface controllers, transceiver support circuits, and digital communications equipment. The device can distribute a clock reference while maintaining a controlled relationship between the source and destination domains. Design validation should confirm output count, jitter, skew, lock behavior, and clock-edge quality in the manufacturer datasheet because those parameters were not included in the verified excerpts.
Recomendado
Embedded Processor Clocking
The MK2302S-01 can support clock distribution around embedded processors and other sequential digital blocks when the design requires regeneration or multiplication. The verified 168 MHz rating and single-circuit classification make it appropriate for systems operating below that headline limit, while the 3.15 V to 3.45 V supply range must match the processor interface environment. A PLL-based buffer can help isolate a clock source from downstream loading, but the engineer must verify startup, acquisition, output impedance, and timing margins before using it as a processor clock source.
Recomendado
Digital Logic Clock Fanout
The MK2302S-01 is relevant to digital-logic designs where one clock reference must reach several sequential elements with controlled distribution. Its CMOS clock output and PLL architecture distinguish it from a passive buffer, allowing the device to regenerate the signal when the source or load conditions require it. Use short routed branches, matched return paths, and verified output loading to prevent added skew and edge degradation. The verified data identifies one circuit but does not provide the complete output-pin map, so the exact fanout configuration must come from the official datasheet.
Recomendado
Test and Measurement Equipment
A PLL-based zero-delay buffer can be useful in test and measurement equipment that generates, conditions, or distributes reference clocks to acquisition and conversion circuits. The MK2302S-01's verified 168 MHz maximum frequency and 3.15 V to 3.45 V operating range make it a candidate for moderate-speed clock architectures, while its one-circuit classification suggests that the complete implementation depends on the package pinout and output configuration. Instrument designs should account for deterministic latency, reference quality, termination, and the difference between nominal propagation delay and actual edge-to-edge timing.
Recomendado
RF and High-Speed Interface Support
The MK2302S-01 may be used in high-speed interface support circuits where a local, regenerated clock is preferable to distributing a noisy or heavily loaded reference directly. The 168 MHz verified headline capability and PLL architecture are compatible with moderate-speed digital interfaces, but RF-clock applications require additional checks for phase noise, jitter, spur behavior, and supply sensitivity. Use short controlled traces, appropriate termination, and a clean reference source. The supplied evidence does not quantify RF-specific timing or noise performance, so the manufacturer datasheet and system measurements are mandatory.
Recomendado
Industrial Control and Data Acquisition
The MK2302S-01 can support clock regeneration in industrial controllers and data-acquisition equipment where digital modules must operate from a stable local timing reference. Its narrow 3.15 V to 3.45 V supply range, 168 MHz maximum frequency, and surface-mount 8-SOIC package are compatible with compact control designs after signal-integrity and thermal validation. The PLL behavior may help isolate the clock source from downstream loads, but the design should verify tolerance to supply variation, temperature, startup sequencing, and long-term clock integrity before deployment.

Notas de projeto
Treat the clock path as a controlled-impedance signal rather than an ordinary logic trace. Route the input and outputs as short as practical, maintain a continuous ground reference, and avoid crossing or running beside switching-power and high-current paths. The PLL architecture does not eliminate PCB-induced skew, loading, or edge degradation; validate the final layout with the manufacturer's recommended topology and measured clock-eye or time-domain requirements.
Keep the 3.15 V to 3.45 V supply range as a hard design constraint. Place local decoupling according to the manufacturer guidance, provide a low-impedance return path, and check power-up and power-down sequencing before enabling downstream logic. Because the verified data does not include current consumption, settling behavior, or absolute maximum ratings, these values must be obtained from the datasheet rather than estimated.
Verify output loading, termination, trace length, and clock-edge requirements at the destination rather than relying on the zero-delay label. A PLL-based buffer can regenerate a clock, but input sensitivity, output drive, duty-cycle distortion, skew, and jitter determine whether the downstream device sees a valid waveform. Use the manufacturer's timing tables and application example, and preserve the intended output topology when comparing suffix variants.
Do not assume that any part containing MK2302S-01 is electrically interchangeable. The verified search results identify related ILF, LFTR, LF, I, and T variants, but they do not fully establish temperature grade, marking, packing, timing, or lifecycle equivalence. Before substitution, compare the exact ordering code, package drawing, pinout, electrical limits, operating-temperature grade, and approved-source documentation.
