Digital Output Interface

The devices offer two different output format options, thus making interfacing to a field-programmable gate array (FPGA) or an application-specific integrated circuit (ASIC) easy. Each option can be easily programmed using the serial interface, as shown in Table 8-1. The output interface options are:

  • One-wire, 1X frame clock, 12X serialization with the DDR bit clock and
  • Two-wire, 1X frame clock, 6X serialization with the DDR bit clock.
