This indicates that Bit 1 of Register 5 is the 4:2:2
output mode select bit.

4:2:2 Output Mode Select
A bit that configures the output data in 4:2:2 mode.
This mode can be used to reduce the number of data
lines used from 24 down to 16 for applications using
YUV, YCbCr, or YPbPr graphics signals. A timing
diagram for this mode is shown in Figure 11.

Extra PLL Divider
A bit that can add an additional divide-by-2 into the
PLL divide ratio. Enabling this function at pixel
frequencies below 20 MHz can result in improved PLL
jitter performance, as it allows the VCO to run at a
higher frequency, resulting in lower jitter.

Two bits that can control the bandwidth of the sync-
on-green input (SOGIN). In most applications, the
SOGIN bandwidth should be set to its maximum
(300 MHz). When there is excessive noise on SOGIN,
reducing the bandwidth can help suppress the noise.

This bit controls the bandwidth of the red, green,
and blue analog inputs. In most applications, the
analog input bandwidth should be set to its maximum
(300 MHz). When there is excessive noise on the
analog inputs, reducing the bandwidth can help
suppress the noise.
