ICS85354-01 DUAL 2:1/1:2 DIFFERENTIAL-TO-LVPECL/ECL MULTIPLEXER The ICS85354-01 is a 2:1/1:2 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 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. A 3rd 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 Block diagrams on pages 2-3 of the data sheet. The ICS85354-01 is optimized for applications requiring very high performance and has a maximum operating frequency in 2.5GHz. The device is packaged in a small, 3mm x 3mm VFQFN package, making it ideal for use on space-constrained boards.

DUAL 2:1/1:2

DIFFERENTIAL-TO-LVPECL/ECL MULTIPLEXER

The ICS85354-01 is a 2:1/1:2 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 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. A 3rd 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

Block diagrams on pages 2-3 of the data sheet.

The ICS85354-01 is optimized for applications requiring very high performance and has a maximum operating frequency in 2.5GHz. The device is packaged in a small, 3mm x 3mm VFQFN package, making it ideal for use on space-constrained boards.
