AD807 Description
The AD807 provides the receiver functions of data quantization, signal level detect, clock recovery and data retiming for 155 Mbps NRZ data. The device, together with a PIN diode/preamplifier bination, can be used for a highly integrated, low cost, low power SONET OC-3 or SDH STM-1 fiber optic receiver. The receiver front end signal level detect circuit indicates when the input signal level has fallen.
