The ICS842023I is an Ethernet Clock Generator and a member of the HiPerClocks TM HiPerClockSTM family of high performance devices from ICS. For Ethernet applications, a 25MHz crystal is used to generate 250MHz. The ICS842023I uses ICS' 3rd generation low phase noise VCO technology and can achieve <1ps r ms phase jitter, easily meeting Ether net jitter requirements. The ICS842023I is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
