ISL58792
Laser Diode Driver with Serial Control and Write Current DAC FN7580
Rev 3.00
December 14, 2015 The ISL58792 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. Features The rise time, fall time and overshoot of all outputs are
adjustable to compensate for high and low resistance lasers. WEN Line Skew Detection The ISL58792 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. 10-bit x 10-bit Multiplying DAC Output Provides 10-bit Full
Scale Adjustment and 10-bit Resolution at any Full Scale
Output The oscillator is internally activated through program
assignment to attach to any WEN state.
The WEN lines have internal 100пЃ— terminators. There is a
skew detector on the WEN receiver outputs. Compatible with all Conventional Controllers Having a Serial
Port, with Some Programming Programmable Snubber on all Outputs Compatible with Future Controllers Having Gray Coded WEN
Lines for Glitchless High-Speed Operation 1000mA Maximum Total Write Output Current. Three Laser Outputs Allow Read/Write DVD, CD, and Blue
Combinations Single +5V Supply Analog Inputs Supports Read APC Applications HFM Oscillator Programmable to 100mAP-P and Range …
