ZHCSGI8A April 2017 – October 2021 ADC12D1620QML-SP
PRODUCTION DATA
In non-ECM, the serial interface is not active, and all available functions are controlled through various pin settings. Non-ECM is selected by setting the ECE pin to logic-high. Note that for the control pins, logic-high and logic-low refer to VA and GND, respectively. Nine dedicated control pins provide a wide range of control for the ADC12D1620 and facilitate its operation. These control pins provide DES mode selection, demux-mode selection, DDR-phase selection, execute calibration, power down I channel, power down Q channel, test-pattern-mode selection, and full-scale input-range selection. In addition to this, two dual-purpose control pins provide for AC- or DC-coupled mode selection and LVDS output common-mode voltage selection. See Table 7-9 for a summary.
