Input Specifications for Sinusoidal Encoder
This section describes the input specifications for the sinusoidal encoder.
Input Waveform
For the sinusoidal encoder, input a sinusoidal differential signal with an amplitude of 1 Vpp between
SIN+ and SIN-.
With GND as the reference voltage, the SIN+ waveform has an amplitude of 0.5 Vpp with the center
line at approximately 2.5 V, whereas the waveform is inverted for SIN-.
