CDB4361
Evaluation Board for CS4361
Features
 Demonstrates recommended layout and
grounding arrangements
 CS8416 receives S/PDIF, & EIAJ-340-
compatible digital audio
 Header for External PCM Audio
 Requires only a digital signal source and power
supplies for a complete digital-to-analog
converter system
Description
The CDB4361 evaluation board is an excellent means
for quickly evaluating the CS4361 24-bit, 20-pin, 6-
channel D/A converter. Evaluation requires an analog
signal analyzer, a digital signal source, and a power
supply. Analog line-level outputs are provided via RCA
phono jacks.
The CS8416 digital audio receiver IC provides the sys-
tem timing necessary to operate the digital-to-analog
converter and will accept S/PDIF, and EIAJ-340-com-
patible audio data. The evaluation board may also be
configured to accept external timing and data signals for
operation in a user application during system
development.

6. ANALOG OUTPUT FILTERING
CDB4361
The analog output on the CDB4361 has been designed according to the CS4361 datasheet. This output circuit in-
cludes an AC coupling cap and a single pole R and C. An additional load resistance may be added by shunting J23,
J24, J38, J39, J42, and J43 to test the CS4361’s load-driving capability. See Figure 44 on page 20 for more details.
7. OPTIONAL MUTE CIRCUITRY
The CDB4361 contains the optional, recommended mute circuitry for the CS4361. This circuitry is designed to min-
imize the potential for clicks and pops. In order for this circuitry to operate properly, a negative supply is required.
This supply is provided by U18. See Figure 45 on page 21 for more details.
