interpolating DAC with JESD204A
10.2.5.4
All slave mode
The external reference is provided by the JESD204A transmitter. All DACs are configured
in slave mode.
The MDS signal is now driven from the transmitter. It is generated at the end of the
inter-lane alignment phase (see the JESD204A standard for details).
The transmitter must also compensate for the DAC latency. Although the DAC has an
internal samples delay line, it cannot handle large delays.
In this mode, PCB layout is also important. The following delay equation applies:
δ

δ
t is the clock skew considered close to DAC pins.
