ICS85354AK REV. C FEBRUARY 19, 2008
General Description
The ICS85354 is a dual 2:1 and 1:2 Multiplexer and
a member of the HiPerClockSTM family of high
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 transmit/receive pair. See Application Section for further
information.
The ICS85354 is optimized for applications requiring very high
performance and has a maximum operating frequency of 3GHz.
The device is packaged in a small, 3mm x 3mm VFQFN package,
making it ideal for use on space-constrained boards.
