8.4 Device Functional Modes
8.4.1 Serializer and Deserializer Operating Modes and Backward Compatibility (CONFIG[1:0])
The DS90UR90xQ-Q1 chipset is also backward-compatible with previous generations of FPD-Link II.
Configuration modes are provided for backwards compatibility with the DS90C241 / DS90C124 FPD-Link II
Generation 1, and also the DS90UR241 / DS90UR124 FPD-Link II Generation 2 chipset by setting the respective
mode with the CONFIG[1:0] pins on the serializer or deserializer as shown in Table 12 and Table 13. The
selection also determine whether the Video Control Signal filter feature is enabled or disabled in Normal mode.
This feature may be controlled by pin or by Register.
