TSW12QJ1600EVM: Maximum number of received lanes (number_of_RX_lanes) in TI-JESD204-IP

Part Number: TSW12QJ1600EVM
Other Parts Discussed in Thread: TI-JESD204-IP,

Hi exparts,

Q1. What is the maximum number of received lanes (number_of_RX_lanes) for TI-JESD204-IP?

Q2. If we set JMODE6 (total 12 lanes) in TSW12QJ1600EVM and receive ADC data with TI-JESD204C-IP, is it possible to configure 1 IPs (number_of_RX_lanes=12) or 2 IPs (number_of_RX_lanes=6)? What are the advantages and disadvantages of each? 

Regards,
Hiromu

    Hi Hiromu,

    The max number of lanes is 16, there is not really a difference between having two IPs of 6 lanes vs 1 IP of 12 lanes.

    At very high lane rates two IPs will make it easier to meet timing, but it is not expected to be an issue with the QJ1600 device.

    Also with two IPs, both ADCs do not need to be synchronized whereas with one IP they will need to be synchronized with SYSREF.

    However, for this type of application I don’t see a way they could ever operate without the ADCs being synchronized.

    Regards,
