Dual 2:1, 1:2 Differential-to-LVDS Multiplexer ICS854S54I-02
DATA SHEET
General Description
Features
The ICS854S54I-02 is a dual 2:1 and 1:2 Multiplexer. 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 allowing direct Advanced Mezzanine Card (AMC)
to Advanced Mezzanine Card communication connected to an
Advanced TCA Backplane via Fabric Hub Board.
• Three differential LVDS output pairs
• Three differential data inputs
• Data pairs can accept the following differential input levels:
LVPECL, LVDS, SSTL
• Maximum output frequency: 1.75GHz
• Propagation delay: 700ps (maximum)
• Part-to-part skew: 275ps (maximum)
• Full 3.3V supply mode
The ICS854S54I-02 is optimized for applications requiring very high
performance and has a maximum operating frequency of 1.75GHz.
The device is packaged in a small, 4mm x 4mm VFQFN package,
making it ideal for use on space-constrained boards.
• -40°C to 85°C ambient operating temperature
• Available in lead-free (RoHS 6) package
