ZHCSGI8A April 2017 – October 2021 ADC12D1620QML-SP
PRODUCTION DATA
The dual data-rate phase (DDRPh) pin selects whether the ADC12D1620 is in 0° mode (logic-low) or 90° mode (logic-high) for DDR mode. For DDR mode, the data may transition either with the DCLK transition (0° mode) or halfway between DCLK transitions (90° mode). If the device is in SDR mode, the DDRPh pin selects whether the data transitions on the rising edge of DCLK (logic-low) or the falling edge of DCLK (logic-high). The DDRPh pin selects the mode for both the I channel: DI- and DId-to-DCLKI phase relationship and for the Q channel: DQ- and DQd-to-DCLKQ phase relationship.
To use this feature in ECM, use the DPS bit in the Configuration Register (Addr: 0h; Bit: 14). See SDR / DDR Clock for more information.
