GENERAL DESCRIPTION
Using a 25MHz 18pF parallel resonant crystal, the following frequencies can be generated based on the 2 frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz and 62.5MHz. <1ps typical rms phase jitter, easily meeting Ethernet jitter requirements. The ICS844004I-01 is packaged in a small 24pin TSSOP package.
