ISL58797 Datasheet | Intersil

To request the full datasheet, please visit .intersil./products/isl58797 Laser Diode Driver with Write Current DAC and PDIC Control Outputs 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 patible with a conventional LDD, but an internal architecture similar to a write strategy LDD. This bination 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 pensate for high and low resistance lasers. The ISL58797 architecture includes dual write current banks, which can be selected using the bank select line, BSEL. This eliminates the need to synchronize the serial port to the media. The oscillator is...
