Using the AXI_CLKGEN IP

Hi,

I need a clock in the ADRV9009/ZCU102 reference design that is 4x faster than the clock generated by axi_adrv9009_rx_clkgen. The clock generated by axi_adrv9009_rx_clkgen will be 61.44MHz so I need to generate a 245.76MHz clock.

I was planning to use the AXI_CLKGEN IP block. The clk input to this block will be the same as the clk input to axi_adrv9009_rx_clkgen. I have a couple of questions;

1) Is this the best approach to generate the 245.76MHz clock.

2) What settings should I use to customise the IP block prior to sythesis/implementation?

3) Do I need to do any further configuration via the AXI interface when the design is running on the FPGA?

Thanks
