Revision 1/December 3, 2001
AN1001
Input Configuration Options (con’d)
The internal 100
W parallel termination is optimized to
provide superior integration and performance in appli-
cations that require:
a)
differential signals
b)
point-to-point routing
c)
50
W transmission line environment.
The inclusion of the termination resistors integrates
four components normally implemented with off-chip
discrete components, thus saving considerable PC board
real estate.
