User Initiated Reset
Recalibration of the A/D can be initiated at any time by driving
the RESETN pin low for a minimum of one clock cycle. An
open-drain driver with a less than 0.5mA pull-up is
recommended, as RESETN has an internal pull-up to OVDD. As is
the case during power-on reset, RESETN and DNC pins must be in
the proper state for the calibration to successfully execute.
The performance of the ISLA222P changes with variations in
temperature, supply voltage or sample rate. The extent of these
changes may necessitate recalibration, depending on system
performance requirements. Best performance will be achieved
by recalibrating the A/D under the environmental conditions at
which it will operate.
A supply voltage variation of <100mV will generally result in an
SNR change of <0.5dBFS and SFDR change of <3dBc.
In situations where the sample rate is not constant, best results
will be obtained if the device is calibrated at the highest sample
rate. Reducing the sample rate by less than 80MSPS will typically
result in an SNR change of <0.5dBFS and an SFDR change of
<3dBc.
and SFDR performance with power on calibration performed at
-40°C, +25°C, and +85°C. Each plot shows the variation of
SNR/SFDR across temperature after a single power on
calibration at -40°C, +25°C and +85°C. Best performance is
typically achieved by a user-initiated power on calibration at the
operating conditions, as stated earlier. However, it can be seen
that performance drift with temperature is not a very strong
function of the temperature at which the power on calibration is
performed.
