After looking at the data sheet it looks like these are a replacement for a potentiometer, not an encoder. One device returns absolute position, the other returns relative position.
It looks like there are a few different ways to communicate with this chip. One is a digital method much like a SPI device and the other is like it was a pot (a pwm signal through a filter which just gives an analog DC-like voltage out; not sure if the filter to do this is on the PCB though). I don't see connections for quadrature output.
