Evaluation Board for CS4391A
Features
Description
z Demonstrates
The CDB4391A evaluation board is an excellent means
for quickly evaluating the CS4391A 24-bit, stereo D/A
converter. Evaluation requires an analog signal
analyzer, a digital signal source, a PC for controlling the
CS4391A (for control port mode only) and a power
supply. Analog line level outputs are provided via RCA
phono jacks.
recommended layout and
grounding arrangements
z CS8414 receives AES/EBU, S/PDIF, &
EIAJ-340 compatible digital audio
z Digital and analog patch areas
z Requires only a digital signal source and
power supplies for a complete Digital-toAnalog (D/A) converter system
The CS8414 digital audio receiver IC provides the system timing necessary to operate the D/A converter and
will accept AES/EBU, S/PDIF, and EIAJ-340 compatible
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.

CDB4391A
1. CDB4391A SYSTEM OVERVIEW
The CDB4391A evaluation board is an excellent means of quickly evaluating the CS4391A. The CS8414
digital audio interface receiver provides an easy interface to digital audio signal sources including the majority of digital audio test equipment. The evaluation board also allows the user to supply clocks and data
through a 10-pin header for system development.
The CDB4391A schematic has been partitioned into 9 schematics shown in Figures 2 through 10. Each
partitioned schematic is represented in the system diagram shown in Figure 1. Notice that the system diagram also includes the interconnections between the partitioned schematics.
2. CS4391A DIGITAL TO ANALOG CONVERTER
A description of the CS4391A is included in the CS4391A data sheet.
3. 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 include a serial bit clock, serial data, left-right clock (FSYNC), deemphasis control and a 256 Fs master clock. The operation of the CS8414 and a discussion of the digital
audio interface are included in the CS8414 data sheet.
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. This allows the CS8414 to decode the de-emphasis bit from the digital audio interface for control of the CS4391A de-emphasis filter,
when the CS4391A is in stand-alone mode.
When the Error Information Switch is activated, the CS8414 operates in the Error and Frequency information mode. The information displayed by the LED's can be decoded by consulting the CS8414 data sheet.
It is likely that the de-emphasis control for the CS4391A will be erroneous and produce an incorrect audio
output if the Error Information Switch is activated and the CS4391A is in the stand-alone mode with internal serial clock mode selected.
Encoded sample frequency information can be displayed 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 located on the
CS8414. When an LED is off, this indicates a "0" on the corresponding pin. Neither the L nor R option of
CSLR/FCK should be selected if the FCK pin is being driven by a clock signal.
The evaluation board has been designed such that the input can be either optical or coax, see Figure 6.
However, both inputs cannot be driven simultaneously.

4. CS8414 DATA FORMAT
The CS8414 data format can be set with switches M0, M1, M2, and M3, as described in the CS8414 data
sheet. The format selected must be compatible with the data format of the CS4391A, as shown in the
CS4391A data sheet. Please note that the CS8414 does not support all the possible modes of the CS4391A
and the Left-Justified Format for the CS8414 and the CS4391A have incompatible serial clocks, see
Table 1. The default settings for M0-M3 on the evaluation board are given in Tables 3-4.

5. INPUT/OUTPUT FOR CLOCKS AND DATA
The evaluation board has been designed to allow interfacing to external systems via the 10-pin header, J9.
This header allows the evaluation board to accept externally generated clocks and data. The schematic for
the clock/data I/O is shown in Figure 9. The 74HC243 transceiver functions as an I/O buffer where HRD1
through HRD6 determine if the transceiver operates as a transmitter or receiver. A transmit function is implemented with all jumpers, HRD1 through HDR6 in the 8414 position. LRCK, SDATA, and SCLK from
the CS8414 will be outputs on J9. The transceiver operates as a receiver with HRD1 through HDR6 in the
EXT_CLK position. MCLK, LRCK, SDATA and SCLK on J9 become inputs.
6. POWER SUPPLY CIRCUITRY
Power is supplied to the evaluation board by six binding posts (GND, +5V(J6), +5V(J1), VL, VCC and
VEE), see Figure 10. The +5V(J6) input supplies power to the +5 volt digital circuitry (V+5, VD+5, VDPC+5), while the VL input supplies power to the Voltage Level Converters and the CS4391A VL pin.
+5V(J1) supplies power to the CS4391A. VCC and VEE supply power to the op-amp and can be +/-9 to
+/-12 volts.
WARNING: Refer to the CS4391A data sheet for maximum allowable voltages levels. Operation outside
of this range can cause permanent damage to the device.
7. GROUNDING AND POWER SUPPLY DECOUPLING
The CS4391A requires careful attention to power supply and grounding arrangements to optimize performance. Figure 10 details the power distribution used on this board. The decoupling capacitors are located
as close to the CS4391A as possible. Extensive use of ground plane fill in the evaluation board yields large
reductions in radiated noise.

8. CONTROL PORT SOFTWARE
The CDB4391A is shipped with Windows based software for interfacing with the CS4391A control port
via the DB25 connector, P1. The software can be used to communicate with the CS4391A in either SPI
or I2C mode; however, in SPI mode the CS4391A registers are write-only. Note: The CDB4391A must
be configured for control port mode as shown in Table 4.
Further documentation for the software is available on the distribution diskette. The documentation is
available in the plain text format file, README.TXT.
9. DSD OPERATION
The CDB4391A supports Direct Stream Digital (DSD) operation through the header for external clocks
and data, J9. The CS4391A must be placed into the DSD mode and the jumpers HDR1 through HDR6 must
be placed into the external clock positions.
