Differential Inputs
The XRD64L43 can be used in either differential or
single-ended input mode. For single-ended inputs, see
the Single-Ended Inputs Section. Differential inputs
reduce system noise by removing noise components
common at both input pins. Figure 5. is a simplified
diagram that is used as a common test circuit with our
XRD64L43ES application board. This circuit is used to
evaluate the dynamic performance of the XRD64L43
using differential inputs. Pin 16, DIFF should be held
high to select differential inputs.

SYNCO, Data Valid Delay and Latency
SYNCO is an output pin provided by the XRD64L43.
Valid data is available on the rising edge of SYNCO,
see Figure 6. The Latency for the XRD64L43 is 17
clock cycles.

Auto-Calibration
The XRD64L43 incorporates an auto-calibration cir-
cuit which continuously adjusts and matches the
offset and linearity of each ADC. This auto-calibra-
tion circuit is transparent to the user after the initial
4.2ms calibration (168,000 initial clock cycles).
Note: To avoid auto-calibration after power down, do
not disable CKIN. CKIN can be slowed down significantly
to save power without losing calibration.
