Description: LC898217XC is the AF control LSI. It consists of 1...
  • LC898217XC is the AF control LSI. It consists of 1 system of feedback circuit for AF control. Built-in equalizer circuit using digital operation. Built-in A/D converter, D/A converter, Constant Current Driver. LC898217XC contains an internal EEPROM. It easily accomplishes Hall calibration and power-on sequence. Also LC898217XC has fast settling function for quickly moving focus lens. This is suitable for small & thinner camera module.
  • Features
  • Built-in equalizer circuit using digital operation
    - AF control equalize circuit
    - Any coefficient can be specified by 2-wire serial I/F (TWIF) - Auto focus performance is good at focusing time and suitable for any types of actuators
  • 2-wire serial interface
    (The communication protocol is compatible with I2C) - Auto sequence for moving initial location after power-on
  • Built-in Constant Current Driver
    - 1-channel - Auto Hall calibration
  • Built-in A/D converter
    - Input 1-channel - Suitable for small & thinner camera module
  • Built-in D/A converter
    - Output 2-channel (Hall offset, Constant current bias) - Minimal external component
  • Built-in VGA
    - Hall Amp
    - 1-channel - Current driver makes a camera module less noise
  • Built-in EEPROM : 128 byte (16 byte/page)
  • Built-in OSC
  • Supply Voltage : VDD (2.6 V to 3.3 V)
