FUNCTION CONTROL
The PCM1807 has the following functions which can be controlled through the serial control port. When the
LRCK (f
), SCKI, MD[1:0], or FMT bit is changed on the fly, a clock-halt reset or an immediate reset by PDWN or
SRST via the serial control port is recommended to obtain stable analog performance.

The MUTE bit controls fade-in and fade-out operation for DOUT. When the MUTE bit is set from 0 to 1, the
fade-out operation provides step-down digital attenuation to prevent a pop noise. When the MUTE bit is set from
1 to 0, the fade-in operation provides a step-up digital gain to prevent a pop noise. The digital output of DOUT
behaves as shown in
Figure 18
.

By setting PREV = 1, the PCM1807 inverts the data on DOUT relative to that of the analog signal on V
L/V
R
(pin 13/pin 14). Because the inversion occurs immediately after the PREV bit changes, pop noise can be
generated at the change. It is recommended that MUTE or PDWN be asserted before using PREV.
