AGC CHARACTERISTICS
The XPD0250CT-001 can handle input optical power from 6µW to 1.7mW which is equivalent to a dynamic range of 49dB. At low input optical power, the transimpedance gain ZT must be high to obtain enough output voltage, and the noise should be low enough to guarantee a minimum bit error rate. The transimpedance is regulated from 4 ㏀ at low input optical...
