CDB8416
Evaluation Board for the CS8416 and CS8406
Features
GCS8416 Digital Audio Receiver
GCS8406 Digital Audio Transmitter
GReceives and transmits AES/EBU, S/PDIF
and EIAJ-340 compatible digital audio
GAnalog and Digital 3.3 Volt supply
G3.3 to 5.0 Volt Logic Interface supply
GOperates in stand alone Hardware Mode or
computer controlled Software Mode
GBalanced and unbalanced inputs available
Description
The CDB8416 is designed to allow easy evaluation of
the CS8416 and CS8406. The board is designed for
easy connection to an Audio Precision or other digital au-
dio test system.
Input and output data may be set for either balanced us-
ing the XLR connectors or unbalanced using the coax or
optical connectors.
Windows PC software provides a GUI to make configu-
ration easy in Software Mode. The software
communicates through the PC’s parallel port to control
the internal registers so that all the possible software
modes of the CS8416 and CS8406 may be tested.

1.7 LED Function Indicators
Several LEDs are provided to indicate board func-
tions. D9 indicates that power is present to the
VD+/VA+ section of the CS8416 and CS8406.
D11, D12, and D13 indicate the status of the
2. CONFIGURATION SETTINGS
NV/RERR, AUDIO, and 96 kHz output of the
CS8416 in Hardware Mode. See the CS8416 data
sheet for an explanation of the conditions that acti-
vate each of these outputs.
