Laser Diode Driver with Serial Control and Write
Current DAC
ISL58792
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.
The rise time, fall time and overshoot of all outputs are
adjustable to compensate for high and low resistance lasers.
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.
The oscillator is internally activated through program assignment
to attach to any WEN state.
The WEN lines have internal 100terminators. There is a skew
detector on the WEN receiver outputs.
Applications
• Combination DVD, CD, and Blue Writable Drives
