Description

General part information

845252I Series

The 845252I is a 3.3V/2.5V CML clock generator designed for Ethernet applications. The device synthesizes either a 50MHz, 62.5MHz, 100MHz, 125MHz, 156.25MHz, 250MHz or 312.5MHz clock signal with excellent phase jitter performance. The clock signal is distributed to two low-skew differential CML outputs. The device is suitable for driving the reference clocks of Ethernet PHYs. The device 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.
