    RE: LMK04821 phase sync between devices

    Hello, What is the phase differences you are experiencing and what is your output frequency you are observing the different phases at. Are you using SYSREF? Have you seen www.ti.com/.../TIDA-00467 (Synchronizing Multiple JESD204B ADCs for Emitter Position...

    RE: GSPS product configuration for mmWave applications

    Hi David For the ADC portion of the system, the method of TIDA-00467 will work for sampling rates up to 3.072 GSPS (the maximum rated frequency of the LMK04828). One of my colleagues will respond regarding the possibilities of synchronizing the DAC...

    RE: ADC12J4000EVM Synchronization Between Boards

    Hi Ben It is possible to synchronize multiple ADC12J4000EVMs and the TSW14J56EVM capture systems, but it requires some modifications of the ADC EVM from the default setup and there are some constraints on the ADC sample rate. Some of this work has been...

    RE: ADC12J4000 SYSREF output of EVM

    Hi Shimizu If the customer is trying to test multi-converter synchronization with 2 ADC12J400EVM+TSW14J56EVM setups they will need to do more than just enabling the SYSREF outputs for the ADCs. They will also need to synchronize the SYSREF and DEVCLK...

    RE: Multi-device synchronization

    Hi Jeff The most straightforward synchronization approach is described in this TI Design ( http://www.ti.com/tool/TIDA-00467 ). This uses the newer Rev A version of the ADC12J4000EVM which has the necessary connections from the LMK04828 outputs to the...
