CDB4340A/41A
1. CDB4340A/41A SYSTEM OVERVIEW
The CDB4340A/41A evaluation board is an excel-
lent means of quickly evaluating the
CS4340A/41A. The CS8414 digital audio interface
receiver provides an easy interface to digital audio
signal sources including the majority of digital au-
dio test equipment. The evaluation board also al-
lows the user to supply clocks and data through a
10-pin header for system development.
The CDB4340A/41A schematic has been parti-
tioned into 10 schematics shown in Figures 2
through 11. Each partitioned schematic is repre-
sented in the system diagram shown in Figure 1.
Notice that the system diagram also includes
the interconnections between the partitioned sche-
matics.
2. CDB4340A/41A ERRATA
The CS4340A is mounted on the same PCB used to
evaluate the CS4340. Please see tables 3 to 5 for
jumper settings that are not applicable to the
CDB4340A/41A. These jumpers should retain the
default setting from the factory. Also, all SDATA
net names for the CS4340A shall be interpreted as
SDIN, as seen in the pin description of the
CS4340A datasheet.
3. CS4340A/41A DIGITAL TO ANALOG
CONVERTER
A description of the CS4340A is included in the
CS4340A data sheet. A description of the
audio interface are included in the CS8414
Datasheet.
During normal operation, the CS8414 operates in
the Channel Status mode where the LED's display
channel status information for the channel selected
by the CSLR/FCK jumper.
When the Error & Frequency button is enabled, the
CS8414 operates in the Error and Frequency infor-
mation mode. The information displayed by the
LED's can be decoded by consulting the CS8414
data sheet.
Encoded sample frequency information can be dis-
played provided a proper clock is being applied to
the FCK pin of the CS8414. When an LED is lit,
this indicates a "1" on the corresponding pin locat-
ed on the CS8414. When an LED is off, this indi-
cates a "0" on the corresponding pin. Neither the L
or R option of CSLR/FCK should be selected if the
FCK pin is being driven by a clock signal.
5. CS8414 DATA FORMAT
The CS8414 data format can be set with jumpers
M0, M1, M2, and M3, as described the CS8414
datasheet. The format selected must be compatible
with the data format of the CS4340A or CS4341A,
shown in the CS4340A and CS4341A datasheets.
Please note that the CS8414 does not support all the
possible modes of the CS4340A or CS4341A, see
Table 1 for details. The default settings for M0-M3
on the evaluation board are given in Tables 3-5.
CS4341A is included in the CS4341A data sheet.

4. CS8414 DIGITAL AUDIO RECEIVER
The system receives and decodes the standard
S/PDIF data format using a CS8414 Digital Audio
Receiver, Figure 5. The outputs of the CS8414 in-
clude a serial bit clock, serial data, left-right clock
(FSYNC), and a 256 Fs master clock. The opera-
tion of the CS8414 and a discussion of the digital
