FemtoClock® Crystal-to-CML Clock Generator

The ICS845264I is a 3.3V, 2.5V CML clock generator designed for Ethernet applications. The device synthesizes four clock frequencies on two separately selectable output banks. Each bank has either a 62.5MHz, 125MHz, 156.25MHz or 312.5MHz clock signal with excellent phase jitter performance.
