7.4 Device Functional Modes
7.4.1 Serializer and Deserializer Operating Modes and Reverse Compatibility (CONFIG[1:0])
The DS92LV242x chipset is compatible with other single serial lane Channel Link II or FPD-Link II devices.
Configuration modes are provided for reverse compatibility with the DS90C241 / DS90C124 chipset (FPD-Link II
Generation 1) and also the DS90UR241 / DS90UR124 chipset (FPD-Link II Generation 2) by setting the
respective mode with the CONFIG[1:0] pins on the serializer or deserializer as shown in Table 13 and Table 14.
This selection also determines whether the control signal filter feature is enabled or disabled in the normal mode.
This feature may be controlled by pin or by register.
