1 / 54 page 1 MAX3711 125Mbps to 3.125Gbps Integrated Limiting Amplifier/ Laser Driver with Dual-Loop Power Control General Description The MAX3711 limiting amplifier and laser driver provides a highly integrated, low-cost, high-performance PMD solution. The low-jitter laser diode driver provides transmit aver- age power control (APC) of laser bias current as well as an integrated modulation current control loop (extinction ratio control, or ERC). The ERC eliminates the need for temperature lookup tables (LUTs) controlling the modula- tion current. The low-noise limiting amplifier maximizes optical sen- sitivity and has adjustable SD/LOS threshold plus pro- grammable output levels. The differential CML output stage features a slew-rate adjustment for 1.25Gbps operation. Integrated bias current monitor and Tx power monitor enable a low-cost implementation of modules with digital diagnostics. A novel auto-calibration mode enables low-cost fiber optic module production. An integrated 3-wire digital interface controls the laser driver and limiting amplifier functions, and enables communication with a low-cost controller. The MAX3711 is offered in a small, 4mm x 4mm, 24-pin TQFN package with exposed pad, and operates over the -40NC to +95NC temperature range.
