ICS2305M-1

Clock Generators, PLLs, Frequency Synthesizers Overview

The ICS2305M-1 is a low phase noise, high-speed PLL-based zero delay buffer operating at 3.3 V. It provides four low skew CMOS outputs with frequencies from 10 to 133 MHz. The device features zero input-to-output delay and output-to-output skew of less than 250 ps. It includes tri-state mode for board-level testing and accepts a 5 V tolerant CLKIN signal. Packaged in an 8-pin SOIC, it supports industrial temperature ranges.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix against the ordering information table to confirm package type (Tube or Tape and Reel) and temperature grade (Industrial -40 to +85°C or Commercial 0 to +70°C). Ensure lead-free status requirements are met if applicable. Confirm availability as non-green parts have reached end-of-life status.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the base version for standard drive capabilities or the 'H' variant for faster rise and fall times. Choose between Industrial (-40 to +85°C) and Commercial (0 to +70°C) grades based on environmental constraints. Verify shipping packaging preferences such as tubes or tape and reel formats during procurement.
