11.5.2 Digital output buffers: LVDS DDR mode
The digital output buffers can be configured as LVDS DDR by setting bit LVDS/CMOS to 1
(see
Each output should be terminated externally with a 100 Ω resistor (typical) at the receiver
side
Table
The default LVDS DDR output buffer current is set to 3.5 mA. It can be programmed via
the SPI (bits DAVI[1:0] and DATAI[1:0]; see
voltage levels.
