MC2046-2

( DataSheet : www.DataSheet4U.com ) 1.25Gbps Limiting Amplifier MC2046-2/C Postamplifier/Quantiser for Gigabit Ethernet and Fiber Channel Applications Main Features: Low-cost IC, available as die or in QSOP16 and TSSOP20 packages. Fabricated in advanced sub-micron BiCMOS process. Very wide range of operation; suitable for up to 1.5Gbps. 4mV input sensitivity at 1.25Gbps. Pin-compatible, superior replacement for Motorola MC10SX1125 Microcosm MC2044C/MC2045-2 PinCompatible. Programmable input-signal level detect. (Onchip default, saving external components) Fully differential 3.3 volt operation. (5v supported) CMOS and PECL Link-Status variants. General Description: The MC2046-2/C is a 2nd-generation, integrated, high gain limiting amplifier intended for high speed fiberoptics based communications. Normally placed following the photodetector and transimpedance or pre-amplifier, the limiting amplifier provides the necessary gain to give PECL compatible logic outputs. The MC2046-2/C also includes a programmable signal-level detector, allowing the user to set thresholds at which the logic outputs are enabled. Capable of operating over a very wide frequency range, the MC2046-2 supports most fiberoptic industry standards, but it is especially suited to 1.06Gbps Fiber Channel and 1.25Gbps Ethernet. It is pin and functionally compatible with the Motorola MC10SX1125 and earlier Microcosm Post-amplifiers. The MC2046-2 die has both PECL and CMOS Status outputs. Packaged, the MC2046-...
