ADV7390/ADV7391/ADV7392/ADV7393
ADV7392/ADV7393 INPUT CONFIGURATION
The ADV7392/ADV7393 supports a number of different input
modes. The desired input mode is selected using Subaddress 0x01,
Bits[6:4]. The ADV7392/ADV7393 defaults to standard
definition (SD) mode upon power-up. Table 31 provides an
overview of all possible input configurations. Each input mode
is described in detail in this section.
STANDARD DEFINITION
Subaddress 0x01, Bits[6:4] = 000
SD YCrCb data can be input in 4:2:2 format over an 8-, 10-, or 16-
bit bus. SD RGB data can be input in 4:4:4 format over a 16-bit bus.
A 27 MHz 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 in 8-bit and 10-bit modes.
8-Bit 4:2:2 YCrCb Mode
Subaddress 0x87, Bit 7 = 0
Subaddress 0x88, Bits[4:3] = 00
In 8-bit 4:2:2 YCrCb input mode, the interleaved pixel data is
input on Pin P15 to Pin P8, with P8 being the LSB. The ITU-R
BT.601/656 input standard is supported.
10-Bit 4:2:2 YCrCb Mode
Subaddress 0x87, Bit 7 = 0
Subaddress 0x88, Bits[4:3] = 10
In 10-bit 4:2:2 YCrCb input mode, the interleaved pixel data is
input on Pin P15 to Pin P6, with P6 being the LSB. The ITU-R
BT.601/656 input standard is supported.

16-Bit 4:2:2 YCrCb Mode
Subaddress 0x87, Bit 7 = 0
Subaddress 0x88, Bits[4:3] = 01
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.
The pixel data is updated at half the rate of the clock, that is, at a
rate of 13.5 MHz (see Figure 3).
16-Bit 4:4:4 RGB Mode
Subaddress 0x87, Bit 7 = 1
In 16-bit 4:4:4 RGB input mode, the red pixel data is input on
Pin P4 to Pin P0, the green pixel data is input on Pin P10 to
Pin P5, and the blue pixel data is input on Pin P15 to Pin P11.
P0, P5, and P11 are the respective bus LSBs.
The pixel data is updated at half the rate of the clock, that is, at a
rate of 13.5 MHz (see Figure 4).

The input mode is determined by Subaddress 0x01, Bits[6:4].

In SD mode, the width of the input data is determined by Subaddress 0x88, Bits[4:3].

External synchronization signals must be used in this input mode. Embedded EAV/SAV timing codes are not supported.
