125Mbps to 2.5Gbps Integrated Limiting Amplifier/Burst-Mode Laser Driver with Dual-Loop Power Control

Laser Autocalibration Mode Improves Manufacturing Quality and Reliability

Product Details

The MAX3710 limiting amplifier and burst mode laser driver provides a highly integrated, low-cost, high-performance PMD solution for GPON/EPON ONU applications in modules or directly on the ONU board.

The low-jitter laser diode driver provides transmit burst mode average 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 modulation current.

The low-noise limiting amplifier maximizes optical sensitivity and has adjustable SD/LOS threshold plus programmable output levels. The differential CML output stage features a slew-rate adjustment for 1.25Gbps EPON operation. Integrated bias current monitor, burst mode Tx power monitor, and a digital laser power monitor enable a low-cost implementation of the next-generation GPON and EPON 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 MAX3710 is offered in a small, 4mm x 4mm, 24-pin TQFN package with exposed pad, and operates over the -40°C to +95°C temperature range.

Description

The MAX3710 evaluation kit (EV kit) is an assembled demonstration board that provides electrical and optical evaluation of the MAX3710 125Mbps to 2.5Gbps integrated limiting amplifier/burst mode laser driver with dual-loop power control. The controlling software communicates with the EV kit through the USB port of the included card and provides simplified control of all functions of the MAX3710. The EV kit can be fully powered by the USB port, or the user can choose to power the MAX3710 by an external 3.3V supply while the USB port supplies the included HFRD46-1 USB daughter card. The laser connection on the EV board allows attachment of lasers in TO-header packages.
