+3.0V to +5.5V, 125Mbps to 266Mbps  
Limiting Amplifiers with Loss-of-Signal Detector  
General Description  
Features  
The MAX3964 limiting amplifier, with 2mV  
input  
P-P  
♦ Single Supply: +3.0V to +5.5V  
♦ 2mV Input Sensitivity  
sensitivity and PECL data outputs, is ideal for low-cost  
ATM, FDDI, and Fast Ethernet fiber optic applications.  
P-P  
♦ 1.2ns Output Edge Speed  
The MAX3964 features an integrated power detector that  
senses the input-signal power. It provides a received-sig-  
nal-strength indicator (RSSI), which is an analog indica-  
tion of the power level and complementary PECL loss-of-  
signal (LOS) outputs, which indicate when the power  
level drops below a programmable threshold. The  
threshold can be adjusted to detect signal amplitudes as  
low as 2.7mVp-p. An optional squelch function disables  
switching of the data outputs by holding them at a known  
state during an LOS condition.  
♦ Loss-of-Signal Detector with Programmable  
Threshold  
♦ Analog Received-Signal-Strength Indicator  
♦ Output Squelch Function  
♦ Choice of TTL or PECL LOS Outputs  
♦ Compatible with 4B/5B Data Coding  
Ordering Information  
The MAX3965 provides the same functionality, but  
offers TTL-compatible LOS outputs. The MAX3968 pro-  
vides the same functionality as the MAX3964, but has  
data-output edge speed suitable for ESCON and  
266Mbps fibre channel applications.
