INTERNAL TEST PATTERN GENERATION
SD TEST PATTERNS
The ADV739x is able to internally generate SD color bar and
black bar test patterns. For this function, a 27 MHz clock signal
must be applied to the CLKIN pin.
The register settings in Table 61 are used to generate an SD NTSC
75% color bar test pattern. All other registers are set as normal/
default. Component YPrPb output is available on DAC 1 to
DAC 3. On power-up, the subcarrier frequency registers default
to the appropriate values for NTSC.

Subaddress
0x00
0x82
0x84
For CVBS and S-Video (Y/C) output, 0xCB instead of 0xC9
should be written to Subaddress 0x82.
For component RGB output rather than YPrPb output, 0 should
be written to Subaddress 0x02, Bit 5.
To generate an SD NTSC black bar test pattern, the settings
shown in Table 61 should be used with an additional write of
0x24 to Subaddress 0x02.
For PAL output of either test pattern, the same settings are used
except that Subaddress 0x80 is programmed to 0x11, and the
subcarrier frequency (F
in Table 62.

ED/HD TEST PATTERNS
The ADV739x is able to internally generate ED/HD color bar,
black bar, and hatch test patterns. For ED test patterns, a 27 MHz
clock signal must be applied to the CLKIN pin. For HD test
patterns, a 74.25 MHz clock signal must be applied to the
CLKIN pin.
The register settings in Table 63 are used to generate an ED
525p hatch test pattern. All other registers are set as normal/
default. Component YPrPb output is available on DAC 1 to
DAC 3. For component RGB output rather than YPrPb output,
0 should be written to Subaddress 0x02, Bit 5.

0x01
0x31
To generate an ED 525p black bar test pattern, the settings
shown in Table 63 should be used with an additional write of
0x24 to Subaddress 0x02.
To generate an ED 525p flat field test pattern, the settings
shown in Table 63 should be used, except that 0x0D should be
written to Subaddress 0x31.
The Y, Cr, and Cb levels for the hatch and flat field test patterns
can be controlled using Subaddress 0x36, Subaddress 0x37, and
Subaddress 0x38, respectively.
For ED/HD standards other than 525p, the settings shown in
Table 63 (and subsequent comments) are used, except that
Subaddress 0x30, Bits[7:3] are updated as appropriate.
