(Address (SR4–SR0) = 00H)
Figure 50 shows the various operations under the control of
Mode Register 0.
MR0 BIT DESCRIPTION
Output Video Standard Selection (MR00–MR01)
These bits are used to set up the encoder mode. The ADV7190/
ADV7191 can be set up to output NTSC, PAL (B, D, G, H, I),
PAL M or PAL N standard video.
Luminance Filter Select (MR02–MR04)
These bits specify which luma filter is to be selected. The filter
selection is made independent of whether PAL or NTSC is
selected.
Chrominance Filter Select (MR05–MR07)
These bits select the chrominance filter. A low-pass filter can be
selected with a choice of cut-off frequencies (0.65 MHz, 1.0 MHz,
1.3 MHz, 2 MHz, or 3 MHz) along with a choice of CIF or
QCIF filters.
MODE REGISTER 1
MR1 (MR17–MR10)
(Address (SR4–SR0) = 01H)
Figure 51 shows the various operations under the control of
Mode Register 1.
MR1 BIT DESCRIPTION
DAC Control (MR10–MR15)
Bits MR15–MR10 can be used to power down the DACs. This are
used to reduce the power consumption of the ADV7190/ADV7191
or if any of the DACs are not required in the application.

Oversampling Control (MR16)
To enable 4
×
Oversampling this bit has to be set to 1. When
enabled, the data is output at a frequency of 54 MHz.
Note that PLL Enable Control has to be enabled (MR61 = 0) in
4
×
Oversampling mode.
Reserved (MR17)
A Logical 0 must be written to this bit.
