MC2045-2

Fiberoptic Postamplifier Main Features Low-cost IC, available as die or in SOIC16, TSSOP20 and QSOP16 packages. Fabricated in advanced submicron BiCMOS process. Pin-compatible, superior replacement for Signetics NE5224/5. SONET, FDDI, ESCON compatible. Programmable input-signal level detector. Fully differential. Input sensitivity better than 0.8mV at 155Mbps, permitting system sensitivities better than -38dBm (BER 10-9). Fully supports 3.3V and 5V supplies. Differential PECL data and level detect outputs. MC2045-2 Postamplifier/Quantiser for applications to 200Mbps General Description The MC2045-2 is a second-generation, high gain limiting amplifier intended for fiberoptics based communications to 200Mbps. Normally placed following the photodetector and transimpedance or pre-amplifier, the limiting amplifier provides the necessary gain to give ECL compatible 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. www.DataSheet4U.com Ordering Information Part Number MC2045-2S16 MC2045-2T20 MC2045-2Q16 MC2045-2DIEWP MC2045-2WAFER Pin Package SOIC16 TSSOP20 QSOP16 Waffle Pack Expanded whole 8” on a 10” grip ring V ccA C azp C azn V ccE D in D in L im itin g Amp.
