Description
The ICS844001 is a Fibre Channel Clock Generator and a member of the HiPerClocks? family of high performance devices from IDT. The ICS844001I uses an 18pF parallel resonant crystal over the range of 20.4MHz - 28.3MHz. For Fibre Channel applications, a 26.5625MHz crystal is used. The frequency select pin allows the device to generate either 106.25MHz or 212.5MHz from a 26.5625MHz crystal. To generate 187.5MHz for 12Gb Ethernet, a 23.4375MHz crystal is used. The ICS844001 uses IDT's 3rd generation low phase noise VCO technology and can achieve <1ps typical rms phase jitter, easily meeting Fibre Channel and Ethernet jitter requirements. The ICS844001 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
