Front Monitor Diode for Blu-ray/HD-DVD/ DVD/CD with Serial Interface

The ATR1842 is a front monitor diode FMD which controls the laser power of the optical pickup for Blu-ray/HD-DVD, DVD and CD drives in one IC.

With the serial programming interface SPI it is possible to fit the laser power for Blu-ray/HD-DVD, DVD and CD. 2 bits are used to set the mode/gain level and 6 additional bits are used for gain trimming, within ±6 dB. Also setting into sleep mode can be done via the serial programmin interface SPI .

The integrated PIN diode and the high speed amplifier with low output impedance ensures stable driver performance.

All output channels are set to tri-state during sleep mode.

Due to its small package size the ATR1842 is especially suited for applications with low height requirements like SLIM and Ultra-SLIM drives.
