Description

The MAX3964 limiting amplifier, with 2mVP-P input sensitivity and PECL data outputs, is ideal for low-cost ATM, FDDI, and Fast Ethernet fiber optic applications.

The MAX3964 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-ofsignal (LOS) outputs, which indicate when the power level drops below a programmable threshold. The threshold can be adjusted to detect signal amplitudes as low as 2.7mVp-p. An optional squelch function of MAX3964 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 MAX3964, but has data-output edge speed suitable for ESCON and 266Mbps fibre channel applications.

The MAX3964/MAX3965/MAX3968 are available in die form, as tested wafers, and in 20-pin QSOP packages. The MAX3964ETP is available in a 20-pin thin QFN package.
