2. QUICK START
The CDB5560 evaluation board is designed to interface with a data acquisition system. To connect and
configure the CDB5560 perform the following initialization procedure:
DS713DB4
1. Verify that the power supplies are off.
2. Connect the power supplies to the CDB5560 as shown in Table 1 on page 6.
3. Verify that the power is off to the analog input signal & control signal sources.
4. Connect the analog input signal sources to the evaluation board per Table 2 on page 6. Verify from Table 4
5. Configure the CDB5560 by connecting the control signal sources to the evaluation board as shown in
6. Make connections to the SPI™ serial port connector as shown in Table 5 on page 8. The CS5560 ADC
7. Turn on the power supplies to the evaluation board.
8. Apply power to the signal source.
9. Press the Reset switch on the evaluation board.
10. The CS5560 ADC's SPI™ serial port should now be communicating data.

serial port is configured by default to operate in the SSC (Synchronous Self Clocking) mode. Refer to the
CS5560 data sheet for more information on serial communication modes and signal timing.
NOTES:
1. Shaded boxes marked with "OPT. CONFIG." are not necessary for operation in an end user product.
2. Calibration function has been removed from the device but still appears on the PCB. J2 must be shorted (grounded)
for proper operation. See Appendix E for details.
