2 / 37 page preliminary preliminary iC-LNB 18-BIT OPTO ENCODER WITH SPI AND SER/PAR INTERFACES Rev B2, Page 2/37 DESCRIPTION iC-LNB is an optoelectronic encoder IC for absolute linear and angle measuring systems, such as glass scales and encoders. Photodiodes, amplifiers, and comparators, the entire signal conditioning unit, and interfaces for position data output have been mono- lithically integrated into the device. An integrated LED current control with a driver stage allows a transmitting LED to be directly connected (e.g. iC-SN85). The optical receive power is kept constant by the control unit, regardless of tempera- ture and aging effects. The receive power setpoint can be programmed. Should the LED current control exceed its operating range, this is indicated at the error message output (end-of-life alarm at pin ERR). The photocurrent offset and photocurrent amplitude of the analog sine/cosine signals can be calibrated. These calibrated voltage signals are lead out to pins PSIN, NSIN, PCOS, and NCOS and are used by the integrated 8-bit vector-tracking interpolation circuit. iC-LNB synchronizes the interpolator and singleturn data to form a contiguous Gray-coded position data word. 16 parallel ports, a scalable shift-register, the SPI interface, as well as incremental A/B/Z signals are available for data output. By help of the unique ’FlexCount’ circuit any angle resolution between 4 to 218 angle steps per revolution can be preset for the incremental signals and the absolute position value. After startup iC-LNB is configured using the SPI inter- face. To make connection to a 3.3 V microcontroller easier, all digital I/O ports, including the SPI, can be run on 3.3 V. |
