• Manufacturer Part Number: sy55855v
• Description: Sy55855v Dual Cml/pecl/lvpecl-to-lvds Translator
• Manufacturer: Micrel Semiconductor

Micrel, Inc.
specifies a small swing of 350mV typical, on a nominal
1.25V common mode above ground. The common mode
voltage has tight limits to permit large variations in ground
between an LVDS driver and receiver. Also, change in
common mode voltage, as a function of data input, is also
kept tight, to keep EMI low.
