Preliminary data sheet
11.5.1 Digital output buffers: CMOS mode
11.5 Digital outputs
The digital output buffers can be configured as CMOS by setting bit LVDS/CMOS to 0
(see
Each digital output has a dedicated output buffer. The equivalent circuit of the CMOS
digital output buffer is shown in
OGND/V
Each buffer can be loaded by a maximum of 10 pF.
The output resistance is 50 Ω and is the combination of the an internal resistor and the
equivalent output resistance of the buffer. There is no need for an external damping
resistor. The drive strength of both data and DAV buffers can be programmed via the SPI
in order to adjust the rise and fall times of the output digital signals (see
