MK2308S-2 개요
A zero-delay buffer is a clock and timing IC that uses a phase-locked loop to compensate propagation delay between an input clock and its outputs. In the broader hierarchy, this device belongs to clock generators, PLL-based frequency synthesizers, clock buffers, and timing ICs. Its CMOS output and bypass mode make it useful where clock distribution, testing, or phase alignment is required.
The verified listing identifies the device as a zero-delay buffer with a maximum frequency of 133.3 MHz, one circuit, a 16-SOIC package, PLL operation with bypass, and clock input. The package is a surface-mount SOIC format with a stated width of 3.90 mm. These details identify the MK2308S-2 as a timing-integrity component rather than a general-purpose logic gate or power-management device.
Because the supplied source material does not include a complete manufacturer electrical table, details such as supply voltage, output count, skew, jitter, propagation delay, temperature range, and exact pin names remain marked as data needed. Designers should consult the manufacturer datasheet and verify the pinout, voltage requirements, and timing limits before layout or production use.
Typical uses include processor and FPGA clock distribution, communication-system clock conditioning, test-and-measurement clock networks, and general digital systems requiring low-skew clock fan-out. The supplied cross-reference data identifies MK2308S-2LF as a pin-compatible replacement candidate, while a comparison result also names CY2308SC-2T for evaluation. Both require package, timing, and application-specific verification rather than automatic substitution.
For implementation, preserve short, controlled-impedance clock traces, provide the required bypass and decoupling capacitors, and keep the PLL input and outputs away from noisy high-current switching paths. Confirm whether bypass mode is required during startup or test before finalizing the system clock architecture.

일반적인 애플리케이션
MK2308S-2 적합 용도: 6 애플리케이션s: FPGA Clock Distribution, Processor Clock Conditioning, Communication-System Clock Networks, Test and Measurement Equipment, Network Interface Clocking, General Digital Clock Distribution.
FPGA Clock Distribution
The MK2308S-2 is suitable for evaluating an FPGA clock-distribution path because the verified listing identifies a zero-delay buffer with PLL bypass, CMOS clock output, one circuit, and operation up to 133.3 MHz. The PLL can compensate propagation delay through the clock network, helping preserve phase relationships between source and distributed clocks. Designers should use short, controlled-impedance clock routes, verify output loading, and confirm the exact output count and timing limits from the manufacturer datasheet. Bypass mode can support test or alternate routing, but it should be controlled only after confirming the required clock architecture and startup behavior.
추천
Processor Clock Conditioning
The MK2308S-2 can be considered for processor clock conditioning when the system needs phase-aligned clock distribution and the clock remains within the verified 133.3 MHz maximum. Its PLL-based zero-delay-buffer function is intended to reduce input-to-output propagation-delay effects while CMOS outputs support digital clock networks. Layout quality is critical: keep the clock path away from noisy power converters, use a continuous return path, and place decoupling close to the device. The supplied sources do not specify supply voltage, output count, skew, or jitter, so processor interface timing must be validated before release.
추천
Communication-System Clock Networks
For communication equipment, the MK2308S-2 offers a verified 133.3 MHz maximum-frequency zero-delay clock-buffer function with PLL bypass and CMOS output. This makes it a candidate for distributing a reference clock among multiple digital sections while controlling phase alignment through the clock network. The design must account for trace length, load capacitance, return-path continuity, and clock-source jitter. Because the supplied data does not specify output count or timing skew, engineers should compare the complete datasheet parameters against the communication subsystem requirements and verify EMI margins in the final board.
추천
Test and Measurement Equipment
The MK2308S-2 can be evaluated for test and measurement clock networks that require a clean, phase-controlled reference clock. Its PLL-based zero-delay behavior and bypass capability provide two potential clock-path modes, while the verified 133.3 MHz ceiling covers moderate digital instrumentation clocks. Designers should isolate the clock route from analog and switching sections, maintain controlled impedance, and provide local bypass capacitors. The available sources do not confirm supply voltage, jitter, skew, or output loading, so laboratory characterization and datasheet review are required before using the part in precision timing equipment.
추천
Network Interface Clocking
The MK2308S-2 may be considered in network-interface clocking where a distributed digital clock must remain phase aligned across multiple circuit blocks. The verified 133.3 MHz maximum frequency and PLL bypass support make it relevant to Ethernet, serial-interface, or embedded network subsystems operating below that limit. The clock network should use short branches, controlled impedance, and a quiet reference-clock source to minimize skew and susceptibility to EMI. Verify the exact package, output count, voltage, and timing specifications in the Renesas documentation because those details are not fully present in the supplied search excerpts.
추천
General Digital Clock Distribution
The MK2308S-2 is broadly applicable to digital clock distribution where a PLL-based zero-delay buffer can align a clock across local logic. Its CMOS output and bypass mode make it useful for laboratory, industrial, and embedded digital systems, provided the operating frequency remains at or below 133.3 MHz. Implement the device near the clock source or central distribution point, maintain a continuous ground reference, and avoid routing the clock adjacent to high dv/dt nodes. Since the verified data does not state supply voltage, output count, or timing uncertainty, confirm those parameters before production use.

설계 노트
Keep the input clock, PLL path, and outputs on short, controlled-impedance traces with a continuous return path. Avoid routing the clock adjacent to switching nodes, high-current power paths, and noisy digital interfaces. The verified data identifies a PLL-based zero-delay buffer up to 133.3 MHz, making trace geometry, stub control, and load termination important at higher clock rates. Confirm the exact output count and recommended land pattern from the manufacturer datasheet before fabrication.
Place the required bypass and decoupling capacitors close to the device power pins and preserve a compact ground return. Because the supplied data does not state the supply voltage or recommended capacitance values, do not select capacitors from generic assumptions. Review the exact MK2308S-2 datasheet and reference layout, then validate startup, bypass-mode behavior, and output stability on prototype hardware.
Do not treat every similarly named MK2308 variant as a drop-in replacement. MK2308S-2LF has the strongest supplied replacement evidence because FindIC reports consistent parameters, terminals, and package. MK2308S-1HLFTR is described as an eight-output 3.3 V family member, so its different output architecture may prevent substitution. Confirm pin names, supply voltage, output count, PLL mode, frequency, and timing before changing the BOM.
