DESCRIPTION
PIN
TYPE
1 Positive reference voltage SCAD1, SCAD2 and Level AD
AP2D
2 Ground reference voltage 1 SCAD1, SCAD2 and Level AD
AP2D
3 FM/AM-level input pin. Via this pin the level of the FM signal or level of AP2D
the AM signal is fed to the CDSP. The level information is used in the
DSP for signal correction
4 By I2C switchable common mode reference pin to enable an arbitrary
high common mode analog input.
AP2D
5 Power on Mute of the FADER DAC. Timing is determined by an external APR2D
capacitor.
