MAR2100 | Mirror Controller IC

MAR2100 MIRROR CONTROLLER IC

The MAR2100 is a Driver and control IC for Maradin’s MAR1100 dual-axis MEMS-based scanning mirror. MAR2100 is targeted for miniature laser-based displays and sensors.

MAR2100 drives and controls Maradin’s MAR1100 dual axis scanning mirror and generates the timing signals to synchronize the laser module through the Host, also called as Data Manipulator. As MAR1100 scanner has two uncoupled actuators – one for horizontal scan and one for vertical scan, MAR2100 controller IC supports both drivers. 

KEY FEATURES AND BENEFITS

  • Both Electromagnetic and Electrostatic actuator drivers

  • 2D (Vertical and horizontal) capacitance sensing

  • Programmable Gain and BW for sensing and control circuitry

  • Capacitance calibration of sensors

  • Horizontal control based on MEMS resonance

  • Programmable phase and duty cycle for PLL

  • Programmable number of scan lines

  • Programmable number of retrace lines

  • Field Rate: 60Hz

  • Support interlace/non-interlace modes

  • Option to input external control signals for Vertical and Horizontal loops

  • Timing generator to control RGB module

  • SPI interface with external Host

  • 3v supply with on-chip voltage regulators for analog circuitry

  • Eye Safety Alarm

  • DFT

  • Changeable scan angles in realtime over the scan field
