Overview
Description
The 843SDN is a Gigabit Ethernet Clock Generator and a member of the high performance devices from IDT. The 843SDN uses a 24MHz crystal to synthesize 120MHz. The 843SDN uses IDT's 3rd generation low phase noise VCO technology, and can achieve <1ps rms phase jitter performance over the 12kHz – 20MHz integration range. The 843SDN is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
