Cross talk performance may be effected by PCB patterning and Input resistor “Rin” in relation to input impedance.
Widen intervals of input lines (7pin to 10pin, 29pin to 32pin) and put guard patterns (ground patterns) among input lines
and Monitor outputs (11pin, 28pin) and Tone filters (12pin, 13pin, 26pin, 27pin) for avoiding cross talk problem.
Further, cross talk performance may be effected by input resistor “Rin”. The recommended “Rin” value is 20k
or less.
In consideration of an actual operating condition, please decide Rin values after evaluating. (The NJW1180 input
impedances are 100k
typ.)
