APPLICATIONS
Low Cost 155 Mbps Fiber Optic Receiver
The AD807 and AD8015 can be used together for a complete
155 Mbps Fiber Optic Receiver (Quantizer and Clock Recovery,
and Transimpedance Amplifier) as shown in Figure 14.
The PIN diode front end is connected to a single mode 1300 nm
laser source. The PIN diode has 3.3 V reverse bias, 0.8 A/W
responsively, 0.7 pF capacitance, and 2.5 GHz bandwidth.
The AD8015 outputs (P
constant impedance (50 ) low-pass filter with a 3 dB cutoff
of 100 MHz. The outputs of the low-pass filter are ac coupled
to the AD807 inputs (PIN and NIN). The AD807 PLL damp-
ing factor is set at 7 using a 0.22 F capacitor.
