General Description
The MAX3748/MAX3748A multirate limiting amplifier func-
tions as a data quantizer for SONET, Fibre Channel, and
Gigabit Ethernet optical receivers. The amplifier accepts
a wide range of input voltages and provides constant-
level current-mode logic (CML) output voltages with con-
trolled edge speeds.
A received-signal-strength indicator (RSSI) is available
when the MAX3748/MAX3748A is combined with the
MAX3744 SFP transimpedance amplifier (TIA). A receiver
consisting of the MAX3744* and the MAX3748/
MAX3748A 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
disable can be used to implement squelch.
The combination of the MAX3748/MAX3748A and the
MAX3744 allows for the implementation of all the small-
form-factor SFF-8472 digital diagnostic specifications
using a standard 4-pin TO-46 header. The MAX3748/
MAX3748A is packaged in a 3mm
3mm 16-pin QFN
package with an exposed pad.
