M02015
Low Power CMOS Transimpedance Amplifier with Rx Pwr Mon
Output and AGC for Fiber Optic Networks up to 2.5 Gbps
The M02015 is a CMOS transimpedance amplifier with AGC. The AGC gives a wide dynamic range of 32 dB. The
high transimpedance gain of 9 k⦠ensures good sensitivity.
For optimum system performance, the M02015 die should be mounted with a GaAs or InGaAs PIN photodetector
inside a lensed TO-Can or other optical sub-assembly.
The M02015 can either bias the PIN diode from the internal regulator or use an externally biased PIN diode.
A replica of the average photodiode current is available at the MON pad for photo-alignment and Receive Power
monitoring (SFF-8472 compliant).
