43 / 96 page  ADV7390/ADV7391/ADV7392/ADV7393 Rev. 0 | Page 43 of 96 ENHANCED DEFINITION/HIGH DEFINITION Subaddress 0x01, Bits[6:4] = 001 or 010 ED or HD YCrCb data can be input in a 4:2:2 format over an 8-/10-bit DDR bus or a 16-bit SDR bus. The clock signal must be provided on the CLKIN pin. If required, external synchronization signals can be provided on the HSYNC and VSYNC pins. Embedded EAV/SAV timing codes are also supported. 16-Bit 4:2:2 YCrCb Mode (SDR) In 16-bit 4:2:2 YCrCb input mode, the Y pixel data is input on Pin P15 to Pin P8, with P8 being the LSB. The CrCb pixel data is input on Pin P7 to Pin P0, with P0 being the LSB. 8-/10-Bit 4:2:2 YCrCb Mode (DDR) In 8-/10-bit DDR 4:2:2 YCrCb input mode, the Y pixel data is input on Pin P15 to Pin P8/P6 upon either the rising or falling edge of CLKIN. P8/P6 is the LSB. The CrCb pixel data is also input on Pin P15 to Pin P8/P6 upon the opposite edge of CLKIN. P8/P6 is the LSB. 10-bit mode is enabled using Subaddress 0x33, Bit 2. Whether the Y data is clocked in upon the rising or falling edge of CLKIN is determined by Subaddress 0x01, Bits[2:1] (see Figure 55 and Figure 56). 3FF 00 00 X Y Y0 Y1 Cr0 CLKIN NOTES 1.

ED/HD-DDR Example Application ENHANCED DEFINITION (AT 54 MHz) Subaddress 0x01, Bits[6:4] = 111 ED YCrCb data can be input in an interleaved 4:2:2 format on an 8-/10-bit bus at a rate of 54 MHz. A 54 MHz clock signal must be provided on the CLKIN pin. Embedded EAV/SAV timing codes are supported. External synchronization signals are not supported in this mode. The interleaved pixel data is input on Pin P15 to Pin P8/P6, with P8/P6 being the LSB. 10-bit mode is enabled using Subaddress 0x33, Bit 2. 3FF 00 00 XY Cb0 Y0 Y1 Cr0 CLKIN P[15:8]/P[15:6] NOTES 1. 10-BIT MODE IS ENABLED USING SUBADDRESS 0x33, BIT 2.
