Functional Description Receiver Section

Design

The receiver section for the HFCT-5914ATLZ contains an InGaAs/InP photo detector and a pre-amplifier mounted in an optical subassembly. This optical subassembly is coupled to a post-amplifier/decision circuit on a circuit board. The design of the optical assembly is such that it provides better than 12 dB Optical Return Loss ORL .

The post-amplifier is ac coupled to the pre-amplifier as illustrated in Figure The coupling capacitors are capable of passing the Gigabit Ethernet test pattern at without any significant distortion or performance penalty. If a lower signal rate, or a code which has significantly more low frequency content is used, sensitivity, jitter and pulse distortion could be degraded.

Figure 1 also shows a filter function which limits the bandwidth of the pre-amplifier output signal. The filter is designed to bandlimit the pre-amplifier output noise and thus improve the receiver sensitivity.

These components will reduce the sensitivity of the receiver as the signal bit rate is increased above Gb/s.

The device incorporates a photodetector bias circuit. This output must be connected to VCC and can be monitored by connecting through a series resistor see Application Section .

Noise Immunity

The receiver includes internal circuit components to filter power supply noise. However under some conditions of EMI and power supply noise, external power supply filtering may be necessary see Application Section .
