MODE REGISTER 0
MR0 (MR07–MR00)
(Address (SR4–SR0) = 00H)
Figure 55 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 setup the encoder mode. The ADV7194
can be set up to output NTSC, PAL (B, D, G, H, I), or PAL N
standard video.
Luminance Filter Select (MR02–MR04)
These bits specify which luma lter is to be selected. The lter
selection is made independent of whether PAL or NTSC is
selected.
Chrominance Filter Select (MR05–MR07)
These bits select the chrominance lter. A low-pass lter can be
selected with a choice of cutoff frequencies (0.65 MHz, 1.0 MHz,
1.3 MHz, 2 MHz, or 3 MHz) along with a choice of CIF or
QCIF lters.
MODE REGISTER 1
MR1 (MR17–MR10)
(Address (SR4–SR0) = 01H)
Figure 56 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 ADV7194 or if any
of the DACs are not required in the application.
4
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.
