Hi Experts,

    Hello Ken,
    There is no theoretical limit on the number of chips that can be cascaded. They just need to make sure the 20Ghz SYNC IN signal amplitude on every chip is > -1 dBm. So incase of cascading many devices they might have to use an amplifier to boost up the power of this signal.

    BTW, what kind of use case does your customer have in mind and how many chips are they targeting on cascading?
