CDB4340A/41A
6. ANALOG OUTPUT FILTER
The evaluation board includes a pair of single pole
passive filters. The passive filters, Fig. 3, have a
corner frequency of approximately 95 kHz with
JP3 and JP6 installed and 190 kHz without JP3 and
JP6.
7. INPUT/OUTPUT FOR CLOCKS AND
DATA
The evaluation board has been designed to allow
the interface 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 11. The 74HC243 transceiver functions as
an I/O buffer where jumpers HDR1-HDR6 deter-
mine if the transceiver operates as a transmitter or
receiver. A transmit function is implemented with
the HDR1-HDR6 jumpers in the 8414 position.
LRCK, SDATA, and SCLK from the CS8414 will
be outputs on J9. The transceiver operates as a re-
ceiver with jumpers HDR1-HDR6 in the EXTER-
NAL position. MCLK, LRCK, SDATA and SCLK
on J9 become inputs.
8. POWER SUPPLY CIRCUITRY
Power is supplied to the evaluation board by three
binding posts (GND, +5V, +3V/+5V) (see
Figure 10). The +5V input supplies power to the
+5 Volt digital circuitry (VA+5, VD+5, VDPC+5),
while the +3V/+5V input supplies power to the
DS590DB1
Voltage Level Converter and the CS4340A/41A
for evaluation in either +3 or +5 Volt mode.
9. GROUNDING AND POWER SUPPLY
DECOUPLING
The CS4340A/41A requires careful attention to
power supply and grounding arrangements to opti-
mize performance. Figure 10 details the power dis-
tribution used on this board. The CDB4340A/41A
ground plane is split to control the digital return
currents in order to minimize digital interference.
The decoupling capacitors are located as close to
the CS4340A/41A as possible. Extensive use of
ground plane fill on both the analog and digital sec-
tions of the evaluation board yields large reduc-
tions in radiated noise.
10. CDB4341A CONTROL PORT
SOFTWARE
The CDB4341A is shipped with Windows based
software for interfacing with the CS4341A control
port via the DB25 connector, P1. The software can
be used to communicate with the CS4341A in ei-
ther SPI or I 2 C mode; however, in SPI mode the
CS4341A registers are write-only.
Run SETUP.EXE from the distribution diskette to
install the software. Further documentation for the
software is available on the distribution diskette.
The documentation is available in the plain text for-
mat file, README.TXT.
