I'm looking at fitting one of these to a Cyrus DAD3 player which can be upgraded with a factory plug in QDAC module. It appears the pins to the QDAC match I2S and I have identified most of them on the PCM5102 module, photo below, but don't know what VIN is for.
In addition the QDAC has a pins labelled /ATTEN, TYPE and DOEN that does not appear to be supported on tis module - any idea what these are for?
And has anyone done something similar?
What I have so far is:
Pin Description QDAC pin
--- -------------------------- ----------------
SCK system clock X CLOCK
BCK bit clock BIT CK
DIN data input DATA
LCK data word WORD SEL
GND 0V
VIN ?
FLT filter select TYPE?
DEMP de-emphasis D_EMPH
XSMT soft mute /MUTE
FMT audio format TYPE?
A3V3 3.3 V supply
AGND analog ground
OUTR right channel output
AGND analog ground
OUTL left channel output
