MK2302S-01

Clock Generators, PLLs, Frequency Synthesizers Overview

The MK2302S-01 is a high-performance Zero Delay Buffer (ZDB) and multiplier from the ClockBlocks family, integrating analog/digital Phase-Locked Loop (PLL) techniques. It features two CMOS outputs where CLK2 provides a low-skew divide-by-two of CLK1. The device supports multipliers from 0.5X to 16X via S0/S1 pins, with output frequencies up to 168 MHz at 3.3V. Key electrical parameters include absolute jitter of ±500 ps, propagation delay of ±350 ps, and input-to-output skew of 250 ps max. It operates on 3.3V or 5V supplies in an 8-pin SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify RoHS compliance status when ordering; parts with 'LF' suffix are lead-free. Confirm temperature range requirements: standard commercial grade covers 0°C to +70°C, while industrial versions cover -40°C to +85°C. Check for tape and reel availability if indicated by 'T' suffix. Note that non-green parts may have reached end-of-life status as per manufacturer documentation.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select based on required operating voltage (3.3V or 5V) and environmental conditions. Use industrial variants (-40°C to +85°C) for harsh environments. Ensure feedback path configuration matches desired multiplier setting. Verify package type (SOIC-8) fits board layout constraints. Consider drive strength requirements for connected loads.

Clock Generators, PLLs, Frequency Synthesizers FAQ

How is the zero delay feature achieved?

The rising edge of the input clock (ICLK) aligns with the rising edges of both output clocks (CLK1 and CLK2), creating the appearance of no delay through the device.

What is the relationship between CLK1 and CLK2?

CLK2 is a low-skew divide-by-two version of the CLK1 output signal.

Can the device recover degraded input clock duty cycles?

Yes, the MK2302-01 can recover degraded input clock duty cycles, providing an output clock duty cycle of 45/55.
