iC-NG is a real-time vector-tracking sine/cosine-to-digital converter with an angle resolution of up to 256. The angle can be output via a parallel MCU interface (absolute), or as an encoder quadrature signal with index.
Features
Real-time interpolator with a programmable resolution of up to 256 steps/period
Calibration features permit adaptation of distorted sine/cosine signals
Output with A/B/Z incremental signals of up to 400 kHz, as a parallel 8-bit absolute vector or via a serial interface
Error messaging with excessive input frequency
Programmable index position
Fast 24-bit multiturn counting (position capture with target position interrupt)
