Description
The EL6830 is a combination read + 2 write level laser driver with an extra read + oscillator ROM channel for use in dual-laser 'combo' drivers. A separate (amplitude and frequency) oscillator modulates the selected output for laser noise reduction during read or write. All these functions are provided in a 16-pin QSOP package.
The CD pin, when high, selects the CD (write) laser. Positive current supplied to the IIN lines, through a user-selected resistor, allows the full scale range of each amplifier to be matched to the full scale range of the users control DACs. When the write laser is selected, and the WEN pins are switched low, the respective current is summed to the output with 1ns rise and fall times. Write channel 2 has 300mA output capability with a 300X gain amplifier.
The 100mAP-P (max) oscillator is switched on and off automatically when WEN2 and WEN3 are pulled high.
The entire chip is powered down when ENABLE is low.
