+2.97V to +5.5V, 125Mbps to 200Mbps Limiting  
Amplifier with Loss-of-Signal Detector  
General Description  
Features  
The MAX3645 limiting amplifier functions as a data  
quantizer and is pin compatible with the Mindspeed  
MC2045-2 and MC2045-2Y postamplifiers. The amplifi-  
er accepts a wide range of input voltages and provides  
constant-level positive emitter-coupled logic (PECL)  
output voltages with controlled edge speeds.  
Pin Compatible with the Mindspeed  
MC2045-2/MC2045-2Y  
500µV Input Sensitivity (BER = 10-12  
Compatible with 4B/5B Data Coding  
Programmable LOS Threshold  
)
The MAX3645 features an integrated power detector  
with complementary PECL loss-of-signal (LOS) outputs  
that indicate when the input power level drops below a  
programmable threshold. An optional squelch function  
holds the data outputs at static levels during a  
LOS condition.  
Stable LOS Threshold Over Supply Range  
Output Disable Function and Automatic Squelch  
Single +3.3V or +5.0V Power Supply  
18mA Supply Current  
Ordering Information  
The MAX3645 operates from a single +3.3V or +5.0V  
power supply over a -40°C to +85°C temperature  
range. It is available in 16-pin SO and 16-pin QSOP  
packages.
