The M02090 offers a single, flexible solution that addresses all PON applications of BPON, GEPON and GPON. Capable of independently driving 100 mA of modulation current and 80 mA of bias current, the laser driver in the M02090 can independently control bias and modulation currents via the Eye-Minder TM, a dual closed-loop that maintains the target extinction ratio by compensating for laser aging, temperature, and voltage changes. Open-loop and average closed-loop configurations are also supported. The limiting amplifier inputs in the M02090 have selec- table bandwidth. The input sensitivity is less than 3 mV at 1.25 Gbps, and less than 6 mV at 2.5 Gbps. The positive emitter-coupled logic (PECL) differential outputs achieve full swing at the minimum specified input signal. Also included are features such as programmable loss of signal, received signal strength indication and JAM func- tion, which can be used to squelch chatter on the outputs when no signal is present. Many features of the M02090 can be accessed through a 2-wire interface by an external microcontroller or the device can operate independently with an external EEPROM. The M02090 is offered in a compact 32 pin, 5mm X 5mm QFN package and is specified over an extended operating temperature range of -40ºC to +100ºC. > Integrated 2.5 Gbps burst- mode driver with limiting amplifier > Up to 100mA of modulation current and 80mA of bias current > Dual 2-wire interface enables operation inde- pendently or with an external microcontroller > Dual digital closed-loop architecture, enables real time extinction ratio control > 2.5 ns burst on/off time > Extended temperature range of -40ºC to +100ºC > > K K E E Y Y F F E E A A T T U U R R E E S S 3 3..3 3V V B Bu urrs st t- -M Mo od de e L La as se err D Drriiv ve err a an nd d IIn nt te eg grra at te ed d L Liim miit tiin ng g A Am mp plliiffiie err w wiit th h E Eyye e- -M Miin nd de err T TM M T Te ec ch hn no ollo og gyy ffo orr F Fiib be err- -t to o- -t th he e- -P Prre em miis se es s M M 0 0 2 2 0 0 9 9 0 0 |
