DAC Timing - 4.2 English

The key parameters of the DAC receiver required to calculate end to end latency are:

1. The fixed delay from SYSREF to LEMC (T_RXLEMC)
2. The delay from JESD204C input to LEMC (T_RXIN)
3. The fixed delay from LEMC to analog output (T_RXOUT)

   The delay from SYSREF to LEMC and from LEMC to output must be fixed for a Subclass 1 device, but the delay from JESD204C serial data into LEMC can vary because the receiver buffer compensates for variations in end to end latency. See the following figure.
