I have made a LED transmitter circuit which can reach 100MHz, and I need a high speed receiver circuit, so I picked AD8015. The photodiode I used is SFH250V.
The receiver circuit I built is according to this figure, but I didn't add LPF, quantizer, clock recovery and the capaciors at 6 nd 7 pin. The test point is V1. The result is that the datarate of the receiver circuit is very slow only reach 9KHz. Also the amplitude of the received signal is small. C1=150pF, R=56 Ohm,Vs=8V.
So what caused it? Is there a better application solution?
