General Description
The ICS843SDN is a Gigabit Ethernet Clock Generator. The
ICS843SDN uses a 24MHz crystal to synthesize 120MHz. The
ICS843SDN 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 ICS843SDN is
packaged in a small 8-pin TSSOP, making it ideal for use in
systems with limited board space.
