Next figure shows the circuit model for high-speed digital input. Input is composed of a 3-resistor differential
divider, with 10 k
Ω
resistors, resulting in a total input impedance of 30 k
Ω
. This
bias resistors allow both
single ended and differential input operation
. Noise immunity can be improved by reducing input impedance
with a termination resistor between and HS_GPI-.
High-speed digital inputs electrical equivalent circuit is the following:
