845264 Datasheet (Renesas) - Crystal-to-CML Clock Generator

845264, Crystal-to-CML Clock Generator

The 845264 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.
