The power supply used for the CRD44600-PH-FB is a linear 155 W supply. The supply pro-
vides an unregulated +50 V for the TDA8939 power stages. The power supply consists of a
transformer, diode bridge rectifier, and bulk capacitor. Schematics are shown in Figure 14.
The CS5341 converts analog audio into PCM data for the CS44600. The CS5341 operates
in slave mode and the digital Interface format is set to Left Justified (24-bit).
Analog input is through J5 and J6.
The CS44600 and CS8416 are controlled through the provided control port interface. Con-
nection to the control port is made through J37 (RS-232 Serial). A Windows based GUI pro-
vides control over all the individual registers of the CS44600 and the CS8416.
