BACK-END ERROR (BKND_ERR)
Control signal parameters over recommended operating conditions (unless otherwise noted)
PARAMETER
t
w(ER)
t
p(valid_high)
t
p(valid_low)
Pulse duration, BKND_ERR active (active-low)
Time to stay in the OUT_x low state. After t
p(valid_high)
, the TAS5701 attempts to bring
the system out of the OUT_x low state if BKND_ERR is high.
Time TAS5701 takes to bring OUT_x low after BKND_ERR assertion.
