Look for A/D converters, and every data sheet you choose, based on
desired ADC operation, will include detailed interface information.
Common busses are i2c, SPI, Parallel CMOS, Parallel LVDS.
SPI is the simplest, with lowest pin count, but in the region of
1Msps it becomes too slow, and above that parallel busses are used.
On really fast ( 2GHz+) ADCs, bus expanders are used, so 2Gsps@8bits
fans-out to 500Msps@32bits, where it can (just) feed into a FPGA.
