Implementing an ADC Interface to connect to a FPGA

Hi all,

I want to implement an ADC Interface for an ADC - ADS 7230 (TI) in VHDL. 
I am not very familiar with ADCs to implement it in VHDL. I already have 
an ADC Interface for a 10 bit ADC (MAX 1030) and a 12-bit ADC (LTC1407). 
Unfortunately these are in AHDL.

Is it possible to use any of the existing ADC interfaces and adapt it to 
suit ADS 7230 in AHDL itself? If yes, what are the necessary details I 
should look into from the data sheet to change the existing ADC 
interface available in AHDL?

Or do you have any other suggestions to implement an ADC interface in 
the quickest possible way?

Is there any link where I can get a reference of a 12-bit ADC in VHDL 
similar to ADS 7230?


Thank you!
