ICS85454-01

Integrated Circuit Systems, Inc. ICS85454-01 DUAL 2:1/1:2 DIFFERENTIAL-TO-LVDS MULTIPLEXER FEATURES Dual 2:1/1:2 MUX Three LVDS outputs Three differential inputs Differential inputs can accept the following differential levels: LVPECL, LVDS, CML Loopback test mode available Maximum output frequency: 2.5GHz Part-to-part skew: 250ps (maximum) Additive phase jitter, RMS: 0.05ps (typical) Propagation delay: 550ps (maximum) 2.5V operating supply -40°C to 85°C ambient operating temperature Available in both standard and lead-free RoHS compliant packages GENERAL DESCRIPTION The ICS85454-01 is a 2:1/1:2 Multiplexer and a member of the HiPerClockSTM family of high HiPerClockS™ performance clock solutions from ICS. 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 both 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. Another mode allows loop back testing and allows the output of a PHY transmit pair to be www.DataSheet4U.com routed to the PHY input pair. For examples, please refer to the Application Information section of the data sheet. IC S The ICS85454-01 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 id...
