Laser Diode Driver with Write Current DAC and PDIC Control Outputs

The ISL58797 is a highly integrated, single supply laser diode

Features

driver designed to support multi-standard writable optical

• Compatible with all Conventional Controllers Having a Serial

Port, with Some Programming

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.

• Programmable Snubber on all Outputs

• PDIC (OEIC) Control Pins

• Compatible with Controllers Having Gray Coded WEN Lines

for Glitchless High-Speed Operation

• WEN Line Skew Detection

The rise time, fall time and overshoot of all outputs are

adjustable to compensate for high and low resistance lasers.

• 1000mA Maximum Total Write Output Current

• 10-bit x 10-bit Multiplying DAC Output Provides 10-bit

Full-Scale Adjustment and 10-bit Resolution at any Full-

Scale Output

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.

• Three Laser Outputs Allow Read/Write DVD, CD, and Blue

Combinations

The oscillator is internally activated through program

assignment to attach to any WEN state.

• Single +5V Supply

• Analog Inputs Supports Slope and Read APC

The WEN lines have internal 100Ω termination resistors. There

is a skew detector on the WEN receiver outputs.

• HFM Oscillator Programmable to 100mA

from 100MHz to >1GHz

and Range

P-P

Applications

• Combination DVD, CD, and Blue Writable Drives

• Programmable HFM On, Off and Cooling Levels

• Programmable Spread Spectrum for Low EMI

• BD Camcorders

• Built-in ADC to Sample Laser Voltage Allows Power

Reduction by Optimizing Headroom

• BD Video Recorders

• Built-in Thermal Sensor Aids in Thermal Design

• Serial Input Works up to 50MHz

• Pb-Free (RoHS Compliant)
