To implement the zero-crossing function when switch-
ing audio signals, set the ZCD bit by loading register
00h through the I2C-compatible interface (if the ZCD bit
is not already set). Then set the mute bit low by loading
register 00h. Next, wait for a sufficient period of time for
the audio signal to cross zero. This period is a function
of the audio signal path’s low-frequency 3dB corner
(fL3dB). Thus, if fL3dB = 1kHz, the time period to wait for
a zero-crossing detect is 1/2kHz or 0.5ms.
Next, set the appropriate TV switches using register
01h. Finally, clear the mute bit (while leaving the ZCD bit
high) using register 00h. The MAX4397DA/SA switch the
signal out of mute at the next zero crossing.
To implement the zero-cross function for TV volume
changes, or for TV and phono volume bypass switch-
ing, simply ensure the ZCD bit in register 00h is set.
