DUAL 2:1 AND 1:2 DIFFERENTIALTO-LVDS MULTIPLEXER The ICS85454 is a dual 2:1 and 1:2 Multiplexer and a member of the HiPerClockSTM family of high HiPerClockS performance clock solutions from IDT. The 2:1 Multiplexer allows one of 2 inputs to be selected onto one output pin and the 1:2 MUX switches one input to one of two outputs. This device is useful for multiplexing multi-rate Ethernet PHYs which have 100 M bit and 1000 bit transmit/receive pairs onto an optical SFP module which has a single trasmit/receive pair. See Application Section for further information. The ICS85454 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.
