Overview

The 842023 is an Ethernet Clock Generator and a member of the family of high performance devices from IDT. For Ethernet applications, a 25MHz crystal is used to generate 250MHz. The 842023 uses IDT 3rd generation low phase noise VCO technology and can achieve <1ps rms phase jitter, easily meeting Ethernet jitter requirements. The 842023 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
