ADV7390/ADV7391/ADV7392/ADV7393
ADV7390/ADV7391 INPUT CONFIGURATION
The ADV7390/ADV7391 supports a number of different input
modes. The desired input mode is selected using Subaddress 0x01,
Bits[6:4]. The ADV7390/ADV7391 defaults to standard
definition (SD) mode upon power-up. Table 30 provides an
overview of all possible input configurations. Each input mode
is described in detail in this section.

SD YCrCb data can be input in an interleaved 4:2:2 format over
an 8-bit bus rate of 27 MHz.
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. The ITU-R BT.601/656 input standard
is supported.
The interleaved pixel data is input on Pin P7 to Pin P0, with P0
being the LSB.

ED or HD YCrCb data can be input in an interleaved 4:2:2
format over an 8-bit DDR 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.
8-Bit 4:2:2 ED/HD YCrCb Mode (DDR)
In 8-bit DDR 4:2:2 YCrCb input mode, the Y pixel data is input
on Pin P7 to Pin P0 upon either the rising or falling edge of
CLKIN. P0 is the LSB.
The CrCb pixel data is also input on Pin P7 to Pin P0
upon the opposite edge of CLKIN. P0 is the LSB.
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 50 and Figure 51).
