22 / 48 page ![]() AD9389 Rev. 0 | Page 22 of 48 Hex Address Read/Write or Read Only Bits Default Value Register Name Description [7:4] 0000**** Source Number Source number. 0x14 Read/Write [3:0] ****0000 Word Length Audio word length. 0000 = not specified. 0100 = 16 bits. 0011 = 17 bits. 0010 = 18 bits. 0001 = 19 bits. 0101 = 20 bits. 1000 = not specified. 1100 = 20 bits. 1011 = 21 bits. 1010 = 22 bits. 1001 = 23 bits. 1101 = 24 bits. Default = 0x0. [7:4] 0000**** I2S_SF Sampling frequency for I2S audio. This information is used both by the audio Rx and the pixel repetition. 0011 = 32 kHz. 0000 = 44.1 kHz. 0010 = 48 kHz. 1000 = 88.2 kHz. 1010 = 96 kHz. 1100 = 176.4 kHz. 1110 = 192 kHz. Default = 0x0. [3:1] ****000* VFE_input_id Input video format. 000 = RGB and YCbCr 4:4:4 (Y on Green). 001 = YCbCr 4:2:2; 16-bit, 20-bit, and 24-bit. 010 = Same as 001 with HS and VS embedded as SAV and EAV. 011 = ITU656 with separated syncs. 100 = ITU656 with embedded syncs. 101 = DDR RGB 4:4:4 or YCbCr 4:4:4. 110 = DDR YCbCr 4:2:2. 111 = undefined. Default = 000. 0x15 Read/Write [0] *******0 low_frq_video Video refresh rate. 0 = VREF > 30 Hz. 1 = VREF ≤ 30 Hz refresh rate video. Default = 0. [7:6] 00****** VFE_out_fmt Video output format. This should be written along with 0x45[5:4]. 00 = RGB 4:4:4. 01 = YCbCr 4:4:4. 1x = YCbCr 4:2:2. Default = 00. [5:4] **00**** VFE_422_width 4:2:2 input, could be either 8-bit, 10-bit, or 12-bit. x0 = 12 bits. 01 = 10 bits. 11 = 8 bits. Default = 00. 0x16 Read/Write [3:2] ****00** VFE_input_style Styles refer to the input pin assignments. See Table 23 to Table 28. x0 = Style 1. 01 = Style 2. 11 = Style 3. |
