Parallel Interfaces
25-pin Parallel interface
This interface is used to transfer SDTV resolution 4:2:2 YCbCr data. 8-bit or 10-bit data and a clock are transferred. The individual bits are labeled D0–D9, with D9 being the most significant bit. The pin allocations for the signals are shown in Table 4.24.
