Maxim Integrated (MAX3967AETG+) Laser Diode Driver, 270 Mbps,

Product Overview The MAX3967AETG+ is a 270Mbps SFP LED driver in 24 pin TQFN package. The circuit contains a high-speed current driver with programmable temperature coefficient (tempco), adjustments for LED pre-bias voltage and disable feature. The circuit accepts PECL data inputs and operates from single supply. The SFP LED driver can switch up to 100mA into typical high speed light emitting diodes. As temperature increases, device's modulation current increases with tempco that is programmable from 2500ppm/°C to 12.000ppm/°C. LED pre-bias voltage is programmable from 400mV to 925mV. The pre-bias 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. It is used in multimode LED transmitters, fast Ethernet/FDDI, 155Mbps LAN ATM transceivers, ESCON receivers and SFP transceivers. Supply voltage range is 2.97V to 5.5V Operating temperature range from -40°C to +85°C TX DISABLE for SFP compatibility Adjustable temperature compensation Adjustable modulation current Complementary output reduces supply noise Applications Communications & Networking Product Information Laser Driver Type: SFP / SFF Optical Modules Driver Case Style: TQFN No. of Pins: 24Pins Supply Voltage Min: 2.97V Supply Voltage Max: 5.5V Product Range: - MSL: MSL 1 - Unlimited
