ESCRIPTION
The ICS85354 is a 2:1/1:2 Multiplexer and a mem-
ber of the HiPerClockS
TM
family of high perfor-
HiPerClockS鈩?/div>
mance clock solutions from ICS. The 2:1 Multiplexer
allows one of 2 inputs to be selected onto one out-
put pin and the 1:2 MUX switches one input to one
of two 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
trasmit/receive pair. Please refer to the Application Block dia-
gram on page 2 of the data sheet.
ICS
The ICS85354 is optimized for applications requiring very high
performance and has a maximum operating frequency in excess
of 2GHz. The device is packaged in a small, 3mm x 3mm VFQFN
package, making it ideal for use on space-constrained boards.
