The MAX3969 is a recommended upgrade for the
MAX3964 and MAX3968. The MAX3964A limiting amplifi-
er, with 2mV
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 2.7mV
disables switching of the data outputs by holding them at
a known state during an LOS condition.
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/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.
