MAR '05 DS633RD1 5
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.
1.6 Control Port Interface and GUI
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.
1.7 Unregulated Linear Power Supply
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.
