Frequently Asked Questions
Is the exposed pad on the package connected to ground?
Yes, the exposed pad must be soldered to the ground plane to ensure rated performance.
What is the process for initiating self-calibration?
A minimum of 80 input clock cycles logic low followed by a minimum of 80 input clock cycles high on the CAL pin initiates calibration.
How can I select between SDR or DDR output clocking?
The device supports both SDR and DDR output clocking for flexibility in data acquisition.
How do I put the ADC into a low-power state?
Applying a logic high signal to the PD pin will shift the device into Power Down Mode.
