Description

The EL6241C is a combination read + 2 write level laser driver and IV amplifier, 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 24-lead QSOP package.


The EL6241C CD pin, when high, selects the CD (write) laser. Positive current supplied to the IIN lines, through a user selected resistor, allow 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.

The 100mAP-P (max) oscillator EL6241C is switched on when both OSCEN and OUTEN pins are high. The CD line allows the oscillator to operate at different amplitudes and frequencies for each laser.

The entire chip EL6241C is powered down when ENABLE is low. The user can define the gain of the I/V amplifier. With a slew rate of 200V/s, the I/V amplifier can normally settle to 1% within 30ns.
