Application Information
All NB7L14M inputs can accept PECL, CML, LVTTL,
LVCMOS and LVDS signal levels. The limitations for
differential input signal (LVDS, PECL, or CML) are
minimum input swing of 75 mV and the maximum input
swing of 2500 mV. Within these conditions, the input
voltage can range from V
CC
to 1.2 V. Examples interfaces are
illustrated below in a 50 W environment (Z = 50 W).
