BACK-END ERROR (BKND_ERR)
Control signal parameters over recommended operating conditions (unless otherwise noted)
PARAMETER MIN TYP MAX UNIT
t
w(ER)
Pulse duration, BKND_ERR active (active-low) 350 ns
t
p(valid_high)
Time to stay in the OUT_x low state. After t
p(valid_high)
, the TAS5701 attempts to bring 300
ms
the system out of the OUT_x low state if BKND_ERR is high.
t
p(valid_low)
Time TAS5701 takes to bring OUT_x low after BKND_ERR assertion. 350 ns

MUTE TIMING (MUTE)
Control signal parameters over recommended operating conditions (unless otherwise noted)
PARAMETER MIN TYP MAX UNIT
t
d(VOL)
Volume ramp time. Ramp time = Number of steps × stepsize
(1)
1024 steps
(1) Stepsize = 4 LRCLKs (for 32–48 kHz sample rate); 8 LRCLKs (for 88.2–96 kHz sample rate); 16 LRCLKs (for 176.4–192 kHz sample
rate)
