ICS840001 Description
The ICS840001 is a Fibre Channel Clock Generator and a member of the HiPerClocksTM HiPerClockS™ family of high performance devices from ICS. The ICS840001 uses a 26.5625MHz crystal to synthesize either 106.25MHz or 212.5MHz, using the FREQ_SEL pin. The ICS840001 has excellent phase jitter performance, over the 637KHz 10MHz integration range.
