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).
NOTES
1. SUBADDRESS 0x01 [2:1] SHOULD BE SET TO 00 IN THIS CASE.
2. 10-BIT MODE IS ENABLED USING SUBADDRESS 0x33, BIT 2.
NOTES
1. SUBADDRESS 0x01 [2:1] SHOULD BE SET TO 11 IN THIS CASE.
2. 10-BIT MODE IS ENABLED USING SUBADDRESS 0x33, BIT 2.

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.
