QS7785PF/CF
NIPPON PRECISION CIRCUITS—8
FUNCTIONAL DESCRIPTION
Operating Modes
The QS7785PF/CF operating mode can be con-
trolled over either a parallel interface (P/S = HIGH)
or one of two serial interfaces (P/S = LOW). The
operating mode, control pins and SDA signal rela-
tionship is shown in the table below. Refer to “Serial
Interface Timing” for the SDA signal format.
Output mode
Output signal description
Mono signals should be input on both LIN and RIN.
In output mode 1, the output signal is a mixed signal
comprising the front-channel Qsurround processed
signal and the input stereo signal, that is output on
the 2-channel front speakers only.
In output mode 2, the signal path is the same as in
output mode 1, but the surround effect is enhanced
by increasing the component of the Qsurround pro-
cessed signal and reducing the component of the
input stereo signal.
In output modes 3 and 4, both the front speakers and
surround speakers are used to form a 4-channel sys-
tem for a rich surround space. The front-channel sig-
nal is the same as in output modes 1 and 2. The
surround-channel signal is a mixed signal compris-
ing an enhanced surround effect Qsurround pro-
cessed signal and the input stereo signal.
In output modes 5 to 8, the input signal is a mono
signal. The mono signal is first converted to a virtual
stereo signal and then processed in the same way as
in output modes 1 to 4, respectively. In modes 5 and
6, the surround signal is output on 2-channel front
speakers only. In modes 7 and 8, the surround signals
are output on 4-channel front and surround speakers.
