Description

The ICS854S54I-01 is a 2:1/1:2 Multiplexer. The 2:1 Multiplexer

allows one of two inputs to be selected onto one output pin and the

1:2 MUX switches one input to both outputs. This device may be

useful for multiplexing multi-rate Ethernet PHYs which have 100Mbit

and 1000Mbit transmit/receive pairs onto an optical SFP module

which has a single transmit/receive pair. Another mode allows loop

back testing and allows the output of a PHY transmit pair to be routed

to the PHY input pair. For examples, please refer to the Application

Information section of the data sheet.

The ICS854S54I-01 is optimized for applications requiring very high

performance and has a maximum operating frequency of 2.5GHz.

The device is packaged in a small, 3mm x 3mm VFQFN package,

making it ideal for use on space-constrained boards.
