LVDS Outputs
LVDS specifies a small swing of 325mV typical, on a
nominal 1.20V common mode above ground. The
common mode voltage has tight limits to permit large
variations in ground noise between an LVDS driver
and receiver. These outputs can drive AC- or DC-
coupled differential signals.
The SY89835U can drive long lengths of coaxial
cables and FR4 traces. Table 1 below shows typical
lengths of cables driven at different clock and data
rates.

Notes:
1.
Specifications for the center conductor of the coaxial cables
used are “19 1/19 spcw OD .037 inch ± 0.001”. These are 1m
cables, p/n SB-142 manufactured by Harbour Industries.

2.
The FR4 traces are 6.25mil wide and 6mil thick. Horizontal
distance between adjacent traces is 7.75mil. These traces are
fabricated on a Molex GBX Reference Backplane.
