Gigabit Ethernet Laser Driver Supports DC Coupling At 3.3V

The MC2064 is a highly integrated, programmable FP/DFB laser driver intended for fiber-optic-based communication systems operating at up to 1.25 Gbps. The device is claimed as the first to support dc-coupled output at 3.3V operation and is available in TSSOP-20 and QSOP-16 packages, as well as in die form. The chip supports operation at rates from less than 100 Mbps to 1.25 Gbps. Outputs may be paralleled for 65-mA modulation, and both 3.3V and 5V operation are supported. Rise and fall times are substantially below the Gigabit Ethernet requirement of 250 ps.
