Laser diode driver GN25L80B

GN25L80B is a combined 2.5Gbps DML driver and 1.25Gbps burst mode limiting amplifier for gigabit passive optical network (GPON) optical line terminal (OLT) applications. The laser driver provides optimum performance with reliable dual loop extinction ratio control and eye-shaping. The burst mode limiting amplifier integrates AC-coupling capacitors and meets the timing and sensitivity requirements of Class D of the ITU Multi-PON standard. The GN25L80B has been designed to enable combo-PON modules consisting of GPON, XGS-PON and HS-PON within the same SFP-DD module form factor Features 2.5Gbps DML driver with 1.25Gbps Burst Mode limiting amplifier Fast receiver signal detect Fast receiver burst mode settling time Compact WLCSP package enables triple-gen SFP-DD modules Integrated analog to digital convertor for DDMI compliant implementation Integrated laser safety, mean power and extinction ratio control
