The EL6281C is a combination read + 3 write level laser driver with IV amplifier. A dual amplitude, dual frequency RF oscillator sums on the output for laser noise reduction during read or write. All these functions are provided in 24-lead QSOP and LPP packages.
The ENABLE pin enables the read & write channels. Positive current supplied to the IIN lines, through user selected resistors, allow the full scale range of each amplifier to be matched to the full scale range of the users control DACs. When 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 is switched on and off by the OSCEN line. The R/Wline allows the oscillator to operate at one amplitude and frequency when R/W is high, and another amplitude and fre-quency when R/Wis low.
The entire chip is powered down when ENABLE is low. The user can calibrate the gain of the I/V amplifier. With a slew rate around 200V/s, the I/V amplifier can normally settle to less than 1% within 30ns.
