ATR0885-PFQW

ATR0885-PFQW Datasheet

ATR0885 is a laser diode driver designed to operate three different grounded or floating laser diodes for reading CDs λ = 780 nm , DVDs λ = 650 nm , and HD-DVDs/Blu-ray λ = 405 nm . An on-chip, low-EMI RF oscillator is available to reduce laser mode hopping noise. The oscillator’s current amplitude can be set independently for the three selectable outputs using three resistors RSA, RSB, RSC . The frequency setting is common to all IOUT outputs via a single resistor RF . A logic high level on the ENOSC pin enables the spread-spectrum RF oscillator. The ATR0885 also includes a fast-settling transimpedance amplifier. It is provided to interface between the front-end monitor photo diode and the adaptive laser diode power control circuit. The gain of the transimpedance amplifier can set independently for each of the three outputs using the resistors RTIA, RTIB and RTIC.
