MAX3968 Datasheet | Maxim Integrated

.. 19-1314; Rev 1; 10/02 +3.0V to +5.5V, 125Mbps to 266Mbps Limiting Amplifiers with Loss-of-Signal Detector General Description The MAX3964 limiting amplifier, with 2m V P-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 plementary 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 2.7m Vp-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-patible 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. - Single Supply: +3.0V to +5.5V - 2m VP-P Input Sensitivity - 1.2ns Output Edge Speed - Loss-of-Signal Detector with Programmable Threshold - Analog Received-Signal-Strength Indicator - Output Squelch Function - Choice of TTL or PECL LOS Outputs - patible with 4B/5B Data Coding KIT ATION EVALU E L B AVAILA Features MAX3964/MAX3965/MAX3968 Ordering Information PART MAX3964CEP MAX3964C/D MAX3964C/DW MAX3964ETP MAX3965CEP MAX3965C/D MAX3965C/DW MAX3968CEP MAX3968C/D MAX3968C/DW TEMP RANGE 0o C to +70o C 0o C to +70o C 0 C to +70 C -40o C to +85o C 0o C to +70o C 0 C to +70 C 0o C to +70o C 0o C to +70o C 0 C to +70 C 0o C to +70o C o o o o o o PIN-PACKAGE 20 QSOP Dice- Wafers- 20 Thin QFN 20 QSOP Dice- Wafers- 20 QSOP Dice- Wafers- Applications 125Mbps FDDI Receivers...
