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 performanc.
• 1 LVCMOS/LVTTL output, 7Ω typical output impedence
• Crystal oscillator interface designed for 26.5625MHz, 18pF parallel resonant crystal
• Selectable 106.25MHz or 212.5MHz output frequency
