Compare 2 different datasheets of ADC chip, pin by pin

I have 2 different data sheets for 2 different adc chips. I need to see what conflicts could arise if I changed my design to use the other. Currently, using AD7768-4, a 4 channel adc with 48 pins. want to know conflicts if changed to use MCP3564T-E/NC with 16 pins. obviously need to ignore pins on one that dont match a pin on the other. looking for pin to pin matching. if, for example the clocks in are different, can the MCP3564 be adjusted to match clocks? are the SPI pins compatible? etc. Basically, if the current inputs to the 7768 are provided on the matching input of the 3564, would there be a conflict or not.
