2.7 Gb/s NRZ Data Rate
Laser Diode Driver
Applications * Laser diode driver of an optical transmitter circuit up to 2.7 Gb/s (FEC available)
Functional Description The F0522501Q is a high performance GaAs laser diode driver IC applicable in an optical transmitter circuit up to 2.7 Gb/s NRZ data rate (especially suitable for SDH [STM-16] / SONET [OC-48]) , featuring the capable operation for the FEC signal. The F0522501Q specifies the rise time and the fall time of 70 ps (20 %-80 %) typically. It features the single +5 V or -5 V supply operation, the modulation current between 1 mA and 60 mA, and the bias current between 1 mA and 50 mA while the dissipating power is around the typical value of 1 W.
