5.2 TSW14J56 EVM

D1 and D3 should not be lit for TSW14J56EVM. D2 and D4 should be flashing. These are necessary requirements for the JESD204B transceiver mode to work. D2 flashing indicates the TXDAC JESD204B link has been established, while D4 flashing indicates the RXADC or FBADC JESD204B link has been established.

TRF1208-AFE7950-EVM – data transmission on the DAC and data capture on the ADC should be enabled at this point. The RXNCO, FBNCO, and TXNCO can now be adjusted.

RXDSA, FBDSA, and TXDSA can be adjusted.
