... Blu-ray/DVD/CD Player 1. Description ATR0885 is a laser diode driver designed to operate three different grounded or float- ing laser diodes fo r reading CDs (λ = 780 nm), DVDs (λ 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) ...
