3.4 Digital Output Interface
3-6
The device has separate differential outputs for the I and Q component.
The differential outputs terminate externally (that is, the external
components must provide termination to both differential lines, and the
DAC achieves maximum linearity in differential mode).
The L64777 I and Q component outputs are available in 10-bit digital
format. Depending on the PLL mode, either OCLK or PCLK is the related
clock. The output format can be programmed either as a two’s
complement, or as a sine magnitude representation.
