Low-Power, 622Mbps to 3.2Gbps  
Limiting Amplifier  
General Description  
Features  
The MAX3746 multirate limiting amplifier functions as a  
data quantizer for SONET, Fibre-Channel, and Gigabit  
Ethernet optical receivers. The amplifier accepts a wide  
range of input voltages and provides selectable-level,  
current-mode logic (CML) output voltages with con-  
trolled edge speeds. A received-signal-strength indica-  
tor (RSSI) is available when the MAX3746 is  
DC-coupled to the MAX3744/MAX3724 SFP transim-  
pedance amplifier (TIA). A receiver consisting of the  
MAX3744/MAX3724 and the MAX3746 can provide up  
to 19dB RSSI dynamic range. Additional features  
include a programmable loss-of-signal (LOS) detect, an  
optional disable function (DISABLE), and an  
output-signal polarity reversal (OUTPOL). Output dis-  
able can be used to implement squelch.  
♦ SFP Reference Design Available  
♦ Low 115mW Power Consumption  
♦ 16-Pin QFN Package with 3mm x 3mm Footprint  
♦ 70ps Rise and Fall Time  
♦ Loss-of-Signal with Programmable Threshold  
♦ RSSI Interface (with MAX3744/MAX3724 TIA)  
♦ Output Disable  
♦ Polarity Select  
♦ 8.4psP-P Deterministic Jitter (3.2Gbps)  
♦ Improved EMI Performance  
The combination of the MAX3746 and the MAX3744/  
MAX3724 allows for the implementation of all the small-  
form-factor SFF-8472 digital diagnostic specifications  
using a standard 4-pin TO-46 header.  
♦ Selectable CML Output levels  
♦ Pin Compatible with MAX3748A  
The MAX3746 is pin-for-pin compatible with the  
MAX3748A limiting amplifier and consumes 30% less  
power. The MAX3746 is packaged in a 3mm x 3mm,  
16-pin QFN package.
