Description

RIN1

I

Analog input pin for channel 1 RIN signal. The input analog signal is converted to a 

PCM signal by a PCM CODEC to be provided as the RIN1 signal to the MSM7617.  To 

use the RIN1 pin, set JP1 (RIN1 SEL) to ANLG (refer to the description of JP1). This 

input can be amplified about 0 to +12 dB by VR1.

ROUT1

O

Analog output pin for channel 1 ROUT signal. The MSM7617's ROUT1 signal is 

converted to the analog signal by a PCM CODEC and output on this pin.

SIN1

I

Analog input pin for channel 1 SIN signal. The input analog signal is converted to a 

PCM signal by a PCM CODEC to be provided as the SIN1 signal to the MSM7617.  To 

use the SIN1 pin, set JP2 (SIN1 SEL) to ANLG (refer to the description of JP2).  This 

input can be amplified about 0 to +12 dB by VR2.

SOUT1

O

Analog output pin for channel 1 SOUT signal. The MSM7617's SOUT1 signal is 

converted to the analog signal by a PCM CODEC and output on this pin.
