Description

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. Each clock frequency is distributed to two low-skew differential CML output banks with a total of four outputs. The device is suitable for driving the reference clocks of Ethernet PHYs. It supports 3.3V and 2.5V voltage supply and is packaged in a small, lead-free (RoHS 6) 32-lead VFQFN package. The extended temperature range supports telecommunication, wireless infrastructure, and networking end equipment requirements.
