Atmel has announced two laser diode drivers for 8x DVD dual-layer write speed. The devices extend an existing family of laser diode drivers with Low Voltage Differential Signals (LVDS) for enhanced write speed. The ATR0839 and ATR0849 support DVD±RW/CD-RW combo drives with up to 16x writing speed for DVD±RW and 52x for CD-RW. Due to their maximum output current of more than 700 mA, they also support a write speed of 8x for the new dual-layer DVD±RWs. Since the new devices are provided in very small packages, they are particularly suited for small SLIM drives in notebooks, as well for half-height drives used in desktop PCs and consumer DVD recorders. The two devices provide four-channels, one read channel and three write. The write channels are controlled by LVDS signals. Since the LVDS termination is on-chip, system designers can save three resistors in their bill of materials, which helps reduce space and cost. The two outputs can be used either for DVD laser diodes with a wavelength of 650 nm or for CD laser diodes with a wavelength of 780 nm.
