Description
Reserved
Two MSBs of the N divider in PLL4
8 LSBs of the N divider in PLL4
The value in the VCO4 Range register is
used to adjust the center frequency of PLL4.
Applies pre-emphasis to LVDS output
Adjusts LVDS Differential output swing
Adjusts LVDS Common Mode output voltage
Reserved
5 MSBs of the TOF1 lines per Frame count.
This is read-only and loaded automatically
when Auto Format Detection is enabled
8 LSBs of the TOF1 lines per Frame count.
This is read-only and loaded automatically
when Auto Format Detection is enabled
Together with register 0x3B this is a 13 bit
number which number of lines per frame.
TOF1 will be at a frequency of Hsync divided
by this value.
Reserved
cycles per line to calculate TOF2. It is loaded
automatically based on the format set with
register 0x07.
Reserved
This 13 bit register is loaded automatically
based on the format selected via register
0x07. It sets the number of lines per frame for
the selected format to set the TOF2 rate
correctly.
Reserved
Automatically loaded based on formats
selected.
Reserved
cycles per line to calculate TOF3. It is loaded
automatically based on the format set with
register 0x08.
Reserved
This 13 bit register is loaded automatically
based on the format selected via register
0x08. It sets the number of lines per frame for
the selected format to set the TOF3 rate
correctly.
