Description
The I2S-bus data format being the digital output signal, goes
from the DASP on the CDR main board via flex and connector
JJ01 to the I/O board. Here it is presented to the D/A converter
TDA1305. The DAC's analog outputs pass an amplification
circuit (opamp Q601). After amplification the analog-out L and
R signals pass the filtering circuit and are sent to both the
headphone connector on the headphone board and the HDAM
circuit, analog out cinch connectors on the I/O board. The DAC
uses the CL11-clock (11.2896 MHz), coming from the DASP on
the CDR main board.
