General Description
The EL6277C is a high-performance three channel laser diode current driver that provides controlled current to a grounded laser diode. Channel R and 2 can provide 100mA per channel of DC or pulsed current, while channel 3 can provide 200mA per channel. Channels 2, and 3 must be used as the write channels, with switching speeds of approximately three nanosecond rise/fall time. All three channels are summed together at the IOUT output, allowing the user to create multilevel waveforms in order to optimize laser diode performance. The level of the output current is set by an analog voltage applied to an external resistor which converts the voltage into a current at the IIN pin (near ground). The current seen at this pin is then amplified by 100X to become a current source at pin IOUT. An on-chip 500 MHz oscillator is provided to allow current modulatio……
