Quadrature Output Mode Waveform

@ 24 MHz

The 2 channel quadrature outputs

are 5 V CMOS outputs. The Delta

X count is used to generate the

XB

XA and XB quadrature signals.

The Delta Y count is used to gen-

erate the YA and YB quadrature

signals. Delta X, Y counts are in

the range of +7 to –7 counts of

motion and new Delta X, Y values

are generated at a rate of 2000

Hz. The quadrature signals can

change at a maximum rate of
