TIA56A

TIA56A 56 Gb/s Transimpedance Amplifier Type: Module Brief description The TIA56A is a versatile high-speed transimpedance amplifier for data rates up to 56 Gb/s at >28GHz bandwidth. Key features are: single-ended and differential I/O operation, very high small signal gain, small signal and limiting operation, high cut-off frequency, adjustable input offset, peak level detection output sense for offset control, tunable frequency response, output eye shape adjustment pin, dc and ac coupled operation, single supply voltage. The TIA56A consists of a fully symmetrical differential input buffer. This allows differential as well as single ended drive and is optimized for 50 Ω line termination. For applications which require adjustable input bias or compensation of DC input currents (e.g. photodiodes) the TIA56A allows to adjust the bias input current for each input independently. This feature can e.g. be used for offset cancellation, pulse shaping, duty cycle adjustment or vertical sampling-point adjustment. The TIA56A exhibits a fully symmetrical differential output buffer which provides either one differential output signal or two single ended output signals. The output amplitude is set to typ. 800 mVpp (differential signal). Main fields of application are: TIA for photoreceiver, single-ended to differential conversion, differential to single-ended conversion, amplitude regeneration, active power/signal splitter, 50 Ω line driver.
