Functional Testing Without a DSP or Microcontroller EVM
1-6
Overview
REF+, REF– and 2.5REF are automatically changed when SW1 is
changed. However, some slight adjustment of individual potentiometer
may be necessary.
The I/O signals can be monitored at J7, J11 and J12.
The additional analog inputs can be used for application of external
signals that might be used to digitize signals for further processing. In
short, select the desired analog input channel: implement the data
loopback tests by shunting positions 2–3 of W5 and W7 positions 3–4 with
a jumper connection. With the TMS320C5x DSP, positions 1–2 of W9 are
shorted with a jumper connector or shunt. Positions 2–3 of W9 are shorted
when using either the TMS320C203 or TMS320C54x DSP.

Functional Testing Without a DSP or Microcontroller EVM
With the aid of an arbitrary waveform generator, generating FS, CS, and SCLK
for the device is straight-forward. Configure the device by applying a DATA IN
input waveform of A000h at the falling edge of FS while CS is LOW (refer to
the device datasheet for more information). Then select channel A0 by
grounding the DATA IN input, and activate both CS and FS high-to-low. Apply
the ac analog or dc input to SMA connector J3 and set W2 appropriately.
Simply shunt W5 positions 2–3 and W7 positions 3–4 to connect the ADC
output to the TLC5618A DAC channel B (J14). Observe a replica of the input
signal connected to A0.
