Ti adc jesd This is input to the JESD Interface module as a pll_ref_clk signal. It has JESD Base IP and JESD PHY IP to get JESD data from the ADC12DJxx00 and is compiled for 6G lane rate. cfg" for setting up the ADC and register 208 is x"4'. The GUI loads the FPGA with the appropriate firmware and a specific JESD204B configuration, based on ADC JESD interface configured for 4 lanes, 2 converters, and 1 octet per frame. For those new to www. • Care should be taken about • As there are various data converters elements in a JESD system working in different clock • In case of multiple device alignment of different ADC devices, SYNC signal for each lane is combined in the RX logic device and distributed to all ADCs such that all the ADCs see the SYNC falling edge (active low) in the same frame clock period Our JESD204B ADCs, DACs, clock ICs and development tools enable quick evaluation, design and implementation of designs utilizing the JESD204B interface. *I'm using the altera official JESD ip, again no issue when using it with the evalboard (ADC12J4000 EVM).
