Laser Diode Driver with Write Current DAC and PDIC Control Outputs
ISL58797
The ISL58797 is a highly integrated, single supply laser diode driver designed to support multi-standard writable optical drives in CD, DVD, and Blu-Ray formats at various speeds. It is a ‘hybrid’ part having an interface compatible with a conventional LDD, but an internal architecture similar to a write strategy LDD. This combination adds versatility to the conventional interface. The ISL58797 also features PDIC (OEIC) control pins; which help reduce the signal lines on the Flex cables.
The rise time, fall time and overshoot of all outputs are adjustable to compensate for high and low resistance lasers.
