LMK01801: Question about SYNC

Part Number: LMK01801

Hi TI Experts,

Assume both banks on LMK01801 are configured and synchronized. If I adjust digital delay over SPI and re-send SYNC1 during run time, will this operation affect outputs from Bank0?

 

Thanks,

Terry

  • One More Question, if ClockOut7 (LVCMOS) in Bank A is set (via SPI) to power down then power up again, will the Clk_in  to CLK_out delay change or not?

    According to the block diagram, it seems the in-out delay should be constant that does not change under the same condition, is that correct? I like to know the delay value variation range over power off and on.  I mean, the same configuration, temperature and the same part.

    Thanks,

    Terry

    This will only affect Bank1.

    This is correct, we specify a typical value of 2.25ns.
