The Quadrature decoder (QDEC) provides buffered decoding of quadrature-encoded sensor signals. It is suitable for mechanical and optical sensors.
The main features of QDEC are:
- Digital waveform decoding from off-chip quadrature encoder.
- Sample accumulation eliminating hard real-time requirements to be enforced on application.
- Configurable sample period and accumulation to match application requirements.
- Optional input de-bounce filters.
- Optional LED output signal for optical encoders.
