Simulating with LMK03318 by WEBENCH

- PRIREF input LVPECL-40MHz

- OUT0 : LVPECL-80MHz or 240MHz selectable

- OUT1 : same as OUT0

- OUT4 and OUT5 : LVDS-40MHz

Question

(1) is it possible frequency plan ?

(2) if it is possible, i need detailed control schem in HW-control-mode or SW-control-mode.

Yes, that's possible.

See the LMK03318 EVM user guide for reference schematic and control pin function for Soft pin mode.

Thank you alan.
As you mentioned, I am going to control LMK03318 through i2c interface in soft control mode.
But its Registers are so many that i may spend much times to get the result.
So, could you give the right or estimated setting values for EEPROM in LMK03318 to get the result ?
