Hi,

I require Clock generator with 4 outputs which has different outputs such as (3 number of 200MHz and one 125MHz).

Is there any device which is pre programmed for such outputs or can be programmed through I2C.

Hi Nibin

Wat are the jitter requirements? CDCE925 can support your requirement. You can also use the WEBENCH® Designer at www.ti.com

Hi,

The jitter requirement by FPGA is < 20% of clock input period or 1 ns Max.
All the clocks should be of LVDS standard. So I cannot go with the part suggested by you.

Please let me know the part which suffice my requirement.

Hi Puneet,

I already checked this device, the device works for SPI interface. I have limited IOs in FPGA, so I can go only with I2C interface.
I did not find any devices which suffice my requirement.

Can you please help me on the device selection with I2C inetrface and 5 LVDS output Clock generator.
