11 / 48 page AD9389 Rev. 0 | Page 11 of 48 YCbCr 4:2:2 Formats (24 bits, 20 bits, or 16 bits) with Embedded Syncs, Input ID = 2 An input with YCbCr 4:2:2 with embedded syncs can be selected by setting the input ID (0x15[3:1]) to 0b010. HSYNC and VSYNC are embedded as Start of Active Video (SAV) and End of Active Video (EAV). The input CS (0x16[0]) must be set to 0b1 for proper operation. The data bit width (24 = 12 bits, 20 = 10 bits, or 16 = 8 bits) must be set with 0x16[5:4]. The three input pin assignment styles are shown in Table 12. The input style can be set in 0x16[3:2]. The only difference between Input ID 1 and Input ID 2 is that the syncs on ID 2 are embedded in the data much like ITU 656 running at 1× clock and double width. Table 12.

The Input CS (0x16 [0]) must be set to 0b1. The data bit width (12 bits, 10 bits, or 8 bits) must be set with 0x16[5:4]. The two input pin assignment styles are shown in Table 13. The input style can be set in 0x16[3:2]. Table 13.
