/MAX347B
General Description
Features
The MAX3747/MAX3747A/MAX3747B multirate limiting
amplifiers function as data quantizers for OC-3 through
OC-48 synchronous 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.

feature a programmable loss-of-signal detect (LOS)
and an optional disable function (DISABLE) that can be
combined to implement squelch.

Note 1: The data-input transition time is controlled by a 4th-order Bessel filter with f
= 0.75 x 2.667GHz for all data rates of
-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.
23
Note 6: The PRBS 2 - 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 2A.
Note 9: The signal at the input is switched between 1.2V
and Signal_OFF as shown in Figure 2B.

Input Stage
The input stage is shown in Figure 3. It provides 50Ω ter-
mination to V
for each input signal, IN+ and IN-. The
REF
MAX3747/MAX3747A/MAX3747B should be AC-coupled.

STRUCTURES
Multistage Amplifier
The high-bandwidth multistage amplifier provides
approximately 57dB of gain for the MAX3747 and 61dB
of gain for the MAX3747A/MAX3747B.
Offset Correction Loop
The MAX3747/MAX3747A/MAX3747B are susceptible to
DC offsets in the signal path because they have high gain.
In communication systems using NRZ data with a 50%
duty cycle, pulse-width distortion present in the signal or
generated in the transimpedance amplifier appears as an
input offset and is reduced by the offset correction loop.

The CML outputs of the MAX3747/MAX3747A/

Program the LOS Assert Threshold
Program the LOS assert threshold according to Figure
The MAX3747/MAX3747A/MAX3747B are equipped with
LOS circuitry that indicates when the input signal is below
a programmable threshold, set by a voltage on the TH pin
(see the Typical Operating Characteristics). The voltage
on the TH pin is set by two resistors, one connecting from
5. The combination of R
and R
should be

REF
Select the Coupling Capacitor
input signal amplitude with this threshold and feeds the
signal-detect information to the LOS output, which is open
collector. To prevent LOS chatter in the region of the pro-
grammed threshold, approximately 2dB of hysteresis is
built into the LOS assert/deassert function. Once asserted,
LOS is not deasserted until the input amplitude rises to the
required level. Figure 6 shows the LOS output circuit.
When AC-coupling is desired, coupling capacitors C
IN
and C
should be selected to minimize the receiv-
OUT
er’s deterministic jitter. Jitter is decreased as the input
low-frequency cutoff (f ) is decreased:
