M02011
CMOS Transimpedance Amplifier with AGC for Fiber Optic
Networks up to 622 Mbps
The M02011 is a CMOS transimpedance amplifier with AGC. The AGC gives a wide dynamic range of 40 dB. The
high transimpedance gain of 66 kΩ ensures good sensitivity.
For optimum system performance, the M02011 die should be mounted with a GaAs or InGaAs PIN photodetector
inside a lensed TO-Can or other optical sub-assembly.
The M02011 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 'Loss of Signal'
monitoring.
