NTSC/PAL Video Decoder
ITU-R BT.656 Standard Clipping Level (CLIP)
1 = Clip ITU output to Y range is between 64–940 and
CbCr range is between 64–960.
0 = Clip ITU output to Y range and CbCr range is
between 5–1019 (default).
Inverted Line-Locked Clock (LLC_INV)
This signal inverts the polarity of the line-locked clock
that is output from the MAX9526. This can be used to
solve board level timing problems for other devices.
1 = Invert LLC clock.
0 = Do not invert LLC clock (default).
Input Clock Frequency Select (SEL_54MHz)
1 = 54MHz clock at XTAL/OSC input.
0 = 27MHz clock at XTAL/OSC input (default).
This bit is only applicable when the crystal oscillator is
disabled (XTAL_DIS = 1).
Crystal Oscillator Disable (XTAL_DIS)
1 = XTAL/OSC is either a 27MHz or a 54MHz CMOS
clock input.
0 = Enables the 27MHz crystal oscillator (default).
Horizontal/Vertical Sync Output (HSVS)
1 = D1 and D0 output horizontal and vertical sync
pulses, respectively.
0 = D1 and D0 are LSBs of digital component video
output (default).
The rising edge of horizontal sync (HS) coincides with
the end of active video (rises after 3FFh 000h of EAV
code). The falling edge coincides with the start of
active video (SAV) code (falls after completing 3FFh
000h of SAV code). Figure 18 shows the horizontal and
vertical sync timing.
The vertical sync pulse (VS) line transitions are detailed
in Table 8. Note that the VS line transitions on pin D0
are shifted by 1 to 2 lines relative to the V flag transi-
tions embedded in the ITU data stream. The V flag tran-
sitions embedded in the ITU data stream follow the
ITU-R BT.656-4 standard.
Data Output Disable (DATAZ)
1 = Logic data outputs (D9–D0) are disabled and
placed in high-impedance state.
0 = Logic data outputs (D9–D0) are enabled (default).
The DATAZ bit forces data outputs high impedance
regardless of whether the device is in shutdown.
Clock Output Disable (LLCZ)
1 = Logic clock output (LLC) is disabled and placed
in a high-impedance state.
0 = Logic clock output (LLC) is enabled (default).
The LLCZ bit forces LLC high impedance regardless of
whether the device is in shutdown.
