o Sine/cosine analog track with electronic calibration
o Diff. sine/cosine outputs with 1024 CPR (amplitude: 500 mV)
o Position value of up to 16 bits through 6-bit interpolation
o Quadrature signals with 1024, 2048, 4096, 8192, 16384 CPR
o Index signal in phase with B low
o 14-bit parallel position data output
o Serial data readout in 1 µs cycles at 16 MHz clock frequency
o SPI interface for configuration and position data output
o 3.3 V-compatible SPI and I/O ports
o LED current control for a constant receive power
(50 mA highside driver, sin²+cos² or sum)
o Permanent parity monitoring of the internal RAM bits
o Alarm for configuration and illumination errors (end of life)
