General DescriptionThe MAX3747/MAX3747A multirate limiting amplifiers
function as data quantizers for OC-3 through OC-48 syn-
chronous optical network (SONET), Fibre-Channel, and
Gigabit Ethernet optical receivers. They are pin-for-pin
compatible with the SY88993V from Micrel
Semiconductor, Inc. The amplifiers accept a wide range
of input voltages and provide constant-level, current-
mode logic (CML) output voltages with controlled edge
speeds. The MAX3747 output voltage level is 500mVp-p
and the MAX3747A output voltage is 800mVp-p.
The MAX3747/MAX3747A limiting amplifiers feature a
programmable loss-of-signal detect (LOS) and an
optional disable function (DISABLE). Output disable can
be used to implement squelch.
The MAX3747/MAX3747A are available in a 3mm, 10-pin
µMAX® package ideal for small form-factor receivers.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

2.667Gbps and below. The f-3db= 0.75 x 3.2GHz for a data rate of 3.2Gbps.
Note 2:Supply current is measured with unterminated outputs or with AC-coupled output termination (see Figure 1).
Note 3:Between sensitivity and overload, all AC specifications are met and the output is 0.95 x limited output amplitude.
Note 4:Guaranteed by design and characterization.
Note 5:The deterministic jitter (DJ) caused by the input filter is not included in the DJ generation specification.
Note 6:The PRBS 223- 1 equivalent pattern consists of a K28.5 pattern plus 240 ones plus K28.5 pattern plus 240 zeros.
Note 7:Random jitter was measured without using a filter at the input.
Note 8:The signal at the input is switched between two amplitudes, Signal_ON and Signal_OFF, as shown in Figure 2.
Note 9:VTHis the voltage at pin 5 referenced to VCC(see Figure 5).
