MC2045-2 Datasheet | Mindspeed Technologies

Features Low-cost IC, available as die or in SOIC16, TSSOP20 and QSOP16 packages. Fabricated in advanced submicron Bi CMOS process. Pin-patible, superior replacement for Signetics NE5224/5. SONET, FDDI, ESCON patible. Programmable input-signal level detector. Fully differential. Input sensitivity better than 0.8m V at 155Mbps, permitting system sensitivities better than -38d Bm (BER 10-9). Fully supports 3.3V and 5V supplies. Differential PECL data and level detect outputs. Postamplifier/Quantiser for applications to 200Mbps General Description The MC2045-2 is a second-generation, high gain limiting amplifier intended for fiberoptics based munications to 200Mbps. Normally placed following the photodetector and transimpedance or pre-amplifier, the limiting amplifier provides the necessary gain to give ECL patible logic outputs. The MC2045 also includes a programmable signal-level detector, allowing the user to set thresholds at which the logic outputs are enabled. Though capable of operating over a wide frequency range, the MC2045 has been optimised for 155/200Mbps OC-3/STM-1 and ESCON applications. Note also the MC2044C for applications at 622Mbps and >1Gbps. ..
