TIA 56 Transimpedance Amplifier

TIA 56 is a transimpedance amplifier for the receiver in high-speed opto-electronic transmission systems. Due to the broadband design, the chip can be operated even in small-signal as well as in limiting mode. A strictly differential circuit is used. Both, input and output are terminated with 50 Ohms.

TIA 56 is the successor of the MA40, using state-of-the-art SiGe technology with f_T ~ 200GHz. The chip consists of two main amplifier stages, both in a modified Cherry-Hooper architecture. The subsequent output buffer is optimizied to drive a 50 Ohms external load. Input and output are terminated with 50 Ohms for optimum reflection coefficients. At the ouput high-ohmic resistors are implemented to tap the DC levels of the output signal without influencing the overall frequency response. An offest current can be injected into the OFFS pins.

Package

The TIA56 is available as bare die or as ruggedized module equipped with K-Connectors. Other connector types upon request.

TIA5633 and TIA5652 Transimpedance Amplifier (3.3V and 5.2V)

The TIA56xx is a versatile High-Speed Transimpedance Amplifier for data rates up to 56 Gb/s.

Key features are:

• single-ended and differential I/O operation,
• very high small signal gain,
• small signal and limiting operation,
• high cut-off frequency,
• low noise,
• adjustable input offset,
• output sense for offset control,
• tunable frequency response,
• dc and ac coupled operation,
• adjustable output voltage swing,
• single supply voltage of -3.3 V or -5.2 V

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 ? line driver.

TIA4C-5633 and TIA4C-5652 - 56 Gb/s Quad TIA

The TIA4C-56xx is a versatile High-Speed 4 channel Transimpedance Amplifier for data rates up to 56 Gb/s to match new 100GbE applications.

Key features are:

• 4 independent ampl. Channels,
• single-ended and differential I/O operation,
• very high small signal gain,
• small signal and limiting operation,
• high cut-off frequency,
• low noise,
• adjustable input offset,
• output sense for offset control,
• tunable frequency response,
• dc and ac coupled operation,
• adjustable output voltage swing,
• single supply voltage.

Each channel of the TIA4C-56xx consists of a fully symmetrical differential input buffer. This allows differential as well as single ended drive and is optimized for 50 ? line termination. For applications which require adjustable input bias or compensation of DC input currents (e.g. photodiodes) the TIA4C-5633 allows to adjust the bias input current for each channel independently. This feature can e.g. be used for offset cancellation, pulse shaping, duty cycle adjustment or vertical sampling-point adjustment.
Each channel 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. 500 mV_pp (differential signal) and can be increased to about 1V_pp by using the output swing adjustment pin.

The TIA4C-56xx is available as bare die or as ruggedized module equipped with K-Connectors. Other connector types upon request.
