GENERAL DESCRIPTION
The SFP LED driver can switch up to 100mA into typical high-speed light-emitting diodes. As temperature increases, the device’s modulation current increases with a tempco that is programmable from 2500ppm/°C to 12,000ppm/°C. The modulation current is programmed with a single external resistor. The MAX3967’s LED prebias voltage is programmable from 400mV to 925mV. The prebias circuit produces peaking current, which improves the LED switching speed. Complementary current outputs help to maintain a constant supply current, reducing EMI and supply noise generated by the transmitter module. The MAX3967 is available in die form, or in a 4mm x 4mm, 24-pin thin QFN package. ♦ TX_DISABLE for SFP Compatibility ♦ Single +2.97V to +5.5V Power Supply ♦ Adjustable Temperature Compensation ♦ Adjustable Modulation Current ♦ Complementary Output Reduces Supply Noise ♦ Programmable LED Prebias Voltage ♦ Available in 24-Pin QFN or DieFEATURES
