HD INTERLACE EXTERNAL HSYNC AND VSYNC
CONSIDERATIONS
If the encoder revision code (Subaddress 0xBB, Bits[7:6]) = 01
or higher, the user should set Subaddress 0x02, Bit 1 to high.
To ensure exactly correct timing in HD interlace modes when
using HSYNC and VSYNC synchronization signals. If this bit is
set to low, the first active pixel on each line is masked in HD
interlace modes and the Pr and Pb outputs are swapped when
using the YCrCb 4:2:2 input format. Setting Subaddress 0x02,
Bit 1 to low causes the encoder to behave in the same way as the
first version of silicon (that is, this setting is backward
compatible).
If the encoder revision code (Subaddress 0xBB, Bits[7:6]) = 00,
the setting of Subaddress 0x02, Bit 1 has no effect. In this
version of the encoder, the first active pixel is masked and the
Pr and Pb outputs are swapped when using YCrCb 4:2:2 input
format. To avoid these limitations, use the newer revision of
silicon or use a different type of synchronization.
These considerations apply only to the HD interlace modes
with external HSYNC and VSYNC synchronization (EAV/SAV
mode is not affected and always has exactly correct timing).
There is no negative effect in setting Subaddress 0x02, Bit 0 to
high, and this bit can remain high for all the other video
standards.
ED/HD TIMING RESET
Subaddress 0x34, Bit 0
An ED/HD timing reset is achieved by setting the ED/HD
timing reset control bit (Subaddress 0x34, Bit 0) to 1. In this
state, the horizontal and vertical counters remain reset. When
this bit is set back to 0, the internal counters resume counting.
This timing reset applies to the ED/HD timing counters only.
SD SUBCARRIER FREQUENCY LOCK
Subcarrier Frequency Lock (SFL) Mode
In subcarrier frequency lock (SFL) mode (Subaddress 0x84,
Bits[2:1] = 11), the ADV739x can be used to lock to an external
video source. The SFL mode allows the ADV739x to automatically
alter the subcarrier frequency to compensate for line length
variations. When the part is connected to a device such as an
ADV7403 video decoder that outputs a digital data stream in the
SFL format, the part automatically changes to the compensated
subcarrier frequency on a line-by-line basis (see Figure 63). This
digital data stream is 67 bits wide, and the subcarrier is contained
in Bit 0 to Bit 21. Each bit is two clock cycles long.
