General Description
MC2046-2 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 MC2046-2 has PECL Status outputs and the MC2046-2C has CMOS Status outputs.

MC2046-2 Typical Application
When running PECL outputs into a capacitively coupled 50Ω load, 180Ω pull-down resistors are recommended.
If higher impedance lines are used to matched to a higher impedance load, then larger pull-down resistors may be used.
If higher impedance lines are used to matched to a higher impedance load, then larger pull-down resistors may be used.
