MAX3964AETP
+3 V to +5.5 V, 125 Mbps to 155 Mbps limiting amplifier with loss-of-signal detector
General DescriptionThe MAX3969 is a recommended upgrade for the
MAX3964, MAX3965, and MAX3968. The MAX3964A lim-
iting amplifier, with 2mVP-Pinput sensitivity and PECL
data outputs, is ideal for low-cost ATM, FDDI, and Fast
Ethernet fiber optic applications.
The MAX3964A features an integrated power detector
that senses the input-signal power. It provides a
received-signal-strength indicator (RSSI), which is an
analog indication 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 ampli-
tudes 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.
The MAX3965 provides the same functionality, but offers
TTL-compatible LOS outputs. The MAX3968 provides the
same functionality as the MAX3964A, but has data-output
edge speed suitable for ESCON and 266Mbps fibre
channel applications.
The MAX3964A/MAX3965/MAX3968 are available in die
form, as tested wafers, and in 20-pin QSOP packages.
The MAX3964AETP is available in a 20-pin thin QFN
package.

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.
