where
ρ is the photodiode responsivity in A/W and in is
the RMS noise current in amps. For example, with pho-
todiode responsivity of 0.9A/W, an extinction ratio of 10
and 45nA input-referred noise, the sensitivity of the
MAX3658 is:
Actual results may vary depending on supply noise,
output filter, limiting amplifier sensitivity, and other fac-
tors (refer to application note HFAN-03.0.0:
Accurately
Estimating Optical Receiver Sensitivity).
Maxim obtains -33dBm typ sensitivity combined with
the MAX3748.
Input Optical Overload
Overload is the largest input that the MAX3658 accepts
while meeting the pulse-width distortion specification.
Optical overload can be estimated in terms of average
power with the following equation:
For example, if photodiode responsivity is 1.0A/W, the
input overload is 0dBm.
Optical Linear Range
The MAX3658 has high gain, which limits the output for
large input signals. The MAX3658 operates in a linear
range for inputs not exceeding:
For example, with photodiode responsivity of 0.9A/W
and an extinction ratio of 10, the linear range is:
Interface Schematics
Equivalent Output Interface
The MAX3658 has a differential output structure with
75
Ω termination (150Ω differential). Figure 5 is a simpli-
fied diagram of the output interface. Common test
equipment is designed with a 50
Ω single-ended termi-
nation (100
Ω differential). Figures 6a and 6b show alter-
nate interface schemes for the MAX3658.
