MK2302S-01LF 168MHz Zero Delay Clock Buffer | Renesas
Référence : MK2302S-01LF ✗ Fin de vieMK2302S-01LF Présentation
A zero-delay buffer is a clock-integrity device that reproduces an input clock at its outputs while minimizing the delay between the input transition and the corresponding output transition. The MK2302S-01LF combines Renesas proprietary analog/digital phase-locked-loop techniques with clock-buffer functionality. The device is part of the ClockBlocks family and is intended for higher-speed, lower-voltage clocking requirements.
The MK2302S-01LF supports a maximum clock frequency of 168 MHz and has a specified output skew of 175 ps. Its 8-SOIC surface-mount package is identified as approximately 0.154 inches, or 3.90 mm, wide. The operating temperature range is listed as 0°C to 70°C, and the device is categorized as a clock-driver IC with a CMOS bus interface.
Typical applications include processor and controller clock distribution, data-converter clocking, communications-interface clocking, and general-purpose digital systems requiring a multiplied or buffered clock. In these systems, the device can provide a more controlled clock signal to multiple loads while helping reduce the timing uncertainty associated with directly distributing a high-speed source clock.
The primary design consideration is maintaining the specified 3.15 V to 3.45 V supply range and accounting for the 175 ps output skew in the receiving circuitry. Decoupling should be placed close to the supply pins, and the SOIC footprint should follow the manufacturer's recommended layout for the ClockBlocks zero-delay-buffer family.
This page combines the Renesas family information, technical characteristics, package details, sourcing guidance, drop-in replacement information, and practical implementation notes for engineers evaluating the MK2302S-01LF.

Applications typiques
MK2302S-01LF convient pour 6 applications: Processor Clock Distribution, Data Converter Clocking, Communications Interface Clocking, Legacy Control-System Clocking, FPGA and Digital Logic Timing, Instrumentation and Test Clocking.
Processor Clock Distribution
The MK2302S-01LF is appropriate for distributing a clock to processor or controller logic that operates within a 3.3 V domain. Its 168 MHz maximum frequency and 175 ps specified output skew provide the principal timing parameters for evaluating clock routing margin. The zero-delay-buffer function is useful when the source clock must be reproduced with low, controlled propagation delay, although receiver edge-rate, loading, and board-skew requirements must be checked against the manufacturer timing information.
Recommandé
Data Converter Clocking
The MK2302S-01LF can supply a controlled clock to data-converter circuitry when the required rate and loading fit its 168 MHz capability. The specified 175 ps output skew is important when evaluating relative clock timing at the converter and digital interface. Because the converter may have demanding aperture and sampling requirements, the clock source, trace geometry, return path, and decoupling should be designed together rather than treating the buffer as an isolated component.
Recommandé
Communications Interface Clocking
The MK2302S-01LF fits legacy communications systems that need a low-delay, buffered clock in a 3.3 V domain. Its CMOS interface and 168 MHz maximum frequency make it suitable for digital interfaces operating below that limit, subject to the manufacturer timing and loading limits. The 175 ps skew figure helps establish an initial budget for the relationship between transmitted and received clock edges. Board-level jitter, trace delay, and load mismatch still require separate analysis.
Recommandé
Legacy Control-System Clocking
The MK2302S-01LF can maintain or replicate a clocking architecture in established industrial and control systems that use an 8-SOIC zero-delay-buffer position. The 0°C to 70°C operating range is relevant for commercial-temperature equipment, while the 3.15 V to 3.45 V supply constraint requires a compatible 3.3 V rail. For equipment expected to operate outside that range, verify the full grade requirements and use the appropriate manufacturer-qualified ordering code rather than assuming temperature capability.
Recommandé
FPGA and Digital Logic Timing
The MK2302S-01LF is usable in legacy FPGA and digital-logic designs that need a clock signal with tightly specified skew. The 168 MHz ceiling provides a clear upper limit for the intended operating frequency, and the 175 ps skew specification can be incorporated into a timing budget. The device should be placed close enough to the intended loads to minimize trace skew and reflection, with its supply and ground pins connected to a low-impedance plane and local bypass capacitance.
Recommandé
Instrumentation and Test Clocking
The MK2302S-01LF can provide clock multiplication or zero-delay buffering in legacy instrumentation designs requiring deterministic edge relationships. Its 168 MHz maximum frequency covers many digital measurement and control subsystems, while the 175 ps output skew helps characterize clock-channel consistency. The device remains limited to its 3.15 V to 3.45 V supply and 0°C to 70°C operating range, so enclosure temperature, grounding, and supply-noise conditions must be checked before deployment.

Notes de conception
Place the MK2302S-01LF close to the clock load or split point to minimize trace delay and mismatch. Route the clock on a controlled-impedance path with a continuous reference plane, avoid crossing plane splits, and keep stub lengths short. The specified 175 ps output skew should be considered alongside PCB trace skew so that total edge-to-edge variation remains within the receiving circuit's timing budget.
Operate the device only within the specified 3.15 V to 3.45 V supply range. Place the required input bypass capacitor close to the supply and ground pins and provide a low-impedance return path to the source. Review the datasheet capacitor recommendations against the clock source and load state, and validate startup and shutdown behavior when the regulator ramps through the operating range.
Evaluate source impedance, load capacitance, clock edge rate, and output topology before treating 168 MHz as a guaranteed operating point. Reflections caused by long traces, vias, or unterminated stubs can degrade edge quality even when nominal frequency and skew specifications are satisfied. Keep the clock topology compact, preserve return paths beneath the clock trace, and measure edge shape and eye margin in the final board environment.
Do not substitute an 8-SOIC clock buffer solely from its package dimensions. Confirm pin functions, supply range, frequency rating, output skew, temperature grade, and propagation characteristics in the manufacturer datasheet. For legacy maintenance, MK2302S-01ILF is the identified same-family replacement, but the ordering suffix and current lifecycle status should still be reviewed before procurement.
