1 = Clip ITU output to Y range is between 64–940 and
0 = Clip ITU output to Y range and CbCr range is
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).
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).
1 = XTAL/OSC is either a 27MHz or a 54MHz CMOS
0 = Enables the 27MHz crystal oscillator (default).
1 = D1 and D0 output horizontal and vertical sync
0 = D1 and D0 are LSBs of digital component video
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.
1 = Logic data outputs (D9–D0) are disabled and
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.
1 = Logic clock output (LLC) is disabled and placed
0 = Logic clock output (LLC) is enabled (default).
The LLCZ bit forces LLC high impedance regardless of
whether the device is in shutdown.
