LMK03328: Can LMK03328 generate different frequencies from 10MHz?

Laurie Fung

Part Number: LMK03328

1. We need 307.2MHz, 156.25MHz and 125MHz. Can LMK3328 generate these frequency from the input 10MHz clock?

2. Can OUT7 be used to monitor the input 10MHz clock?

Thanks,

Laurie

    1. Yes, 125 and 156.25 MHz can be generated by PLL1 VCO = 5000 MHz, and 307.2 MHz can be generated by PLL2 VCO = 4915.2 MHz.  These VCO frequencies can be divided-down by the output divider to get the final output frequencies.

    2. Yes, the output muxes on OUT4 to OUT7 can be configured to output a buffered copy of either PRIREF or SECREF inputs.

    Please see this training series for a tutorial on the LMK03328 design, simulation, and programming flow.
