840001I-25 - Renesas

840001I-25 LVCMOS/LVTTL Clock Generator

The 840001I-25 is a General Purpose Clock Generator and a member of the family of high performance devices from IDT. The 840001I-25 can accept frequency from a 22.4MHz to 170MHz and generate a 22.4MHz to 170MHz output. The 840001I-25 has excellent phase jitter performance, from 637kHz – 10MHz integration range. The 840001I-25 is packaged in a small 8-pin TSS.
