Voltage Amplifier Stage

The voltage amplifier stage provides gain and converts

the single-ended input to differential outputs.

100Ω

DC Cancellation Circuit

The DC cancellation circuit uses low-frequency feed-

back to remove the DC component of the input signal

(Figure 3). This feature centers the input signal within

the transimpedance amplifier’s linear range, thereby

reducing pulse-width distortion caused by large input

signals. The DC cancellation circuit is internally com-

pensated and therefore does not require external

capacitors.

OUT-

Output Buffer

The output buffer provides a reverse-terminated voltage

output. The buffer is designed to drive a 100Ω differential

load between OUT+ and OUT-. The MAX3724 must be

DC-coupled to the MAX3748A. See Figures 4 and 5.

Figure 4. Equivalent Output MAX3724

For optimum supply-noise rejection, the MAX3725

should be terminated with a matched load. If a single-

ended output is required, the unused output should be

terminated to a 50Ω resistor to V . The MAX3725

does not drive a DC-coupled, 50Ω grounded load;

however, it does drive a compatible 50Ω CML input.

OUT-

Signal-Strength Indicator

The MAX3724 produces a signal proportional to the

average photodiode current. This is added to the com-

mon mode of the data outputs OUT+ and OUT-. This

signal is intended for use with the MAX3748A to pro-

vide a ground-referenced RSSI voltage.

Applications Information

Signal-Strength Indicator

The SFF-8472 digital diagnostic specification requires

monitoring of input receive power. The MAX3748A and

MAX3724 receiver chipset allows for the monitoring of

the average receive power by measuring the average

DC current of the photodiode.
