MK2304S-2 - 133MHz Zero-Delay Buffer | Renesas | Clock
The Renesas Electronics MK2304S-2 is a 133 MHz zero-delay buffer with one CMOS clock circuit in an 8-SOIC package measuring 0.154 inch, or 3.90 mm, wide. It uses PLL-based zero-delay technology to reproduce a clock signal with low skew, and the verified specifications identify a 1:1 input-to-output ratio. The device operates from a 3 V to 3.6 V supply and supports a 0°C to 70°C temperature range, making it suitable for conventional digital clock-distribution systems that fit those limits.
A zero-delay buffer is a clock and timing IC that compensates clock-propagation delay between a source and downstream circuitry while maintaining a unity frequency relationship between input and output. Within the broader semiconductor hierarchy, it belongs to clock and timing integrated circuits and is functionally associated with clock buffers, clock drivers, and PLL-based synchronization circuits. Its principal engineering benefit is reduced clock skew among receiving devices, provided the power supply, trace topology, and output loading meet the manufacturer's operating requirements.
The MK2304S-2 provides a maximum frequency of 133 MHz, one CMOS output path, PLL capability, and a unity input-to-output ratio. The verified data describes it as a low-jitter, low-skew, high-performance PLL-based buffer for high-speed applications. These characteristics make clock-edge alignment more important than merely restoring a degraded waveform. Designers must also account for supply decoupling, output loading, board-level skew, and the fact that the specified operating temperature is limited to 0°C through 70°C.
Its 8-SOIC surface-mount package supports conventional PCB assembly and compact clock-distribution layouts. The verified operating information specifies a 3 V to 3.6 V supply, CMOS output, and one circuit. Exact propagation delay, input and output capacitance, output current, RMS jitter, cycle-to-cycle jitter, and package dimensions beyond the stated width are not available in the supplied records and must be checked in the manufacturer documentation before release to production.
Typical uses include synchronizing CMOS logic, distributing a common clock among digital components, correcting accumulated board or driver skew, and buffering a clock source in communications, control, or embedded systems. The 133 MHz ceiling makes timing closure critical: propagation delay, output transition behavior, loading, and PCB mismatch can all affect whether the buffer preserves the required edge relationship.
For implementation, follow the manufacturer's recommended 0.1 µF decoupling capacitor from VDD to GND and place it as close as practical to the device. Confirm source and sink capability against the target load, preserve a continuous ground reference, and validate worst-case skew at the actual operating temperature. Do not assume automotive or extended-temperature suitability because the verified range is 0°C to 70°C.
This page combines verified distributor specifications, the manufacturer datasheet link, commercial availability signals, and a cross-brand replacement assessment. It also separates confirmed electrical facts from parameters that still require datasheet verification, helping engineers evaluate the MK2304S-2 without treating unverified timing, jitter, or current limits as guaranteed specifications.
