GN25L98 is a low-cost combined burst mode laser driver and limiting amplifier designed for gigabit passive optical network (GPON) optical networking unit (ONU) applications. GN25L98 features automatic extinction ratio control for reliable operation of the laser over all conditions. A high accuracy auto-ranging A/D converter and on-chip temperature sensor give precise diagnostic reporting. A low-cost integrated avalanche photodiode (APD) controller enables a complete receive solution.
GN25L98 的应用包括模块和 BOSA-on-board ONU。GN25L98 与 GN25L53 跨阻放大器 (TIA) 构成低成本芯片组。
