Disable Function Pin. The data outputs are held static when this pin is asserted high,  
transistor-to-transistor logic (TTL). The data outputs are enabled when this pin is held  
low. LOS functions remain active when outputs are disabled. For normal operation  
connect to GND.

threshold set by the TH input. LOS is deasserted low when the signal level is above  
the threshold.

Detailed Description  
The limiting amplifiers consist of a multistage amplifier,  
offset-correction circuitry, an output buffer, and loss-of-  
signal detect circuitry (see the Functional Diagram).

Input Stage  
The input stage is shown in Figure 3. It provides 50ter-  
mination to V  
for each input signal, IN+ and IN-. The  
REF  
MAX3747A/MAX3747B should be AC-coupled.

STRUCTURES  
Multistage Amplifier  
The high-bandwidth multistage amplifier provides approx-  
imately 61dB of gain for the MAX3747A/MAX3747B.  
Offset Correction Loop  
The MAX3747A/MAX3747B are susceptible to DC offsets  
in the signal path because they have high gain. In com-  
munication systems using NRZ data with a 50% duty  
cycle, pulse-width distortion present in the signal or gener-  
ated in the transimpedance amplifier appears as an input  
offset and is reduced by the offset correction loop.

The offset correction loop sets a low-frequency cutoff of  
3.2kHz.
