HI.I HAV TO INTERFACE MY P89LPC935 WITH PLL ADF4360-4. I NEED THIS PLL TO TUNE TO DIFFERENT FREQUENCIES THAT COULD BE INPUT THROUGH KEYPAD .ALSO I NEED TO KNOW ABOUT THE INPUT CLK FREQUENCIES RANGE OF THIS PLL SO THAT I CAN TUNE MY P89LPC935 OUTPUT TO THAT FREQUENCY.CAN U SUGGEST SOME WAY OR ANY APPROACH THAT I SHOULD FOLLOW.

First. Do not write all upper case. Writing all upper case is consideres shouting and thus _very_ impolite.
Second: Get the damn datasheet of the ADF4360-4, read and understand what it says. There is all the information in it that you need. No one here will look that up for you there.
If you don't know how to read ... well, that's another problem.
Sorry for the RTFM-post, but I think you deserve it. GIYF.

You can have it:
Quick, Accurate, Inexpensive.
Pick two.
Well I hope you have experince in 80c51 micro's as the P89LPC935 is a souped up 80c51 core micro.
Page 21 of the ADF4360-4 data sheet has connections to the ADuC812 80c51 micro

Connect the SPI interface of the P89LPC935 to the ADF4360-4.
For SPI C code of the P89LPC935 see
