The MAX3969 is a recommended upgrade for the MAX3964 and MAX3968. The MAX3964A 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 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 amplitudes 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 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.
