ATR0885

1. Description

ATR0885 is a laser diode driver designed to operate three different grounded or float-

ing 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 inde-

pendently 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 inter-

face 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.
