problem interfacing AD9510 via serial controller

Hi all, I'm trying to implement an analoge capturing project using Xilinx sx55 fpga and AD9510 as ADC. But I'v difficulty to program AD9510 clock distribution IC via its serial controller port to set divider parameters. The problem is that no handshake signal is recieved from serial port. because the signaling between SCP of AD9510 and V4-sx55 can not be simulated, I can not debug my code. I'd like to know has anyone worked with this A/D or other similar ICs? any App-note or practical code?

any comment will be appreciated Thanks

I'm not sure if you made a typo or what. When I looked at the ADI web site they say the 9510 is a PLL clock distribution chip, not an ADC. Perhaps you mean you are using the 9510 as the clock chip in an ADC circuit? So you are asking how to program the 9510 via the serial port?

The control port appears to be a serial port, much like an SPI port. The default operation in fact, is just like SPI. The only restriction is speed is to keep the clock rate no higher than 25 MHz. There is no handshake signals. This is not like RS-232, it is synchronous. The clock and CSB signals control all of the timing. This is all described very well in the serial control port section of the data sheet, page 42.

This is a very complex part, both the control and the details of using it for generating high speed, low skew clocks. You need to study every part of the data sheet and make sure you understand all of the implications before you design it into a project.
