Low-Power, High-Performance
NTSC/PAL Video Decoder
In default mode, the MAX9526 outputs a test pattern
when video is removed. The timing standard for the test
pattern is the last timing standard that is at the output of
the decoder. If the MAX9526 is reset and has no video
inputs, the default output timing standard is 525 lines
(60Hz). See register 0x04 for manually configuring the
video standard decoding. Table 7 gives some common
examples of setting up video standards and test pat-
tern generation.
1 = Force a test pattern at video output.
0 = Output a test pattern if no video is present at the
