The temperature stable ASNT6121 SiGe IC provides low jitter broadband current to voltage conversion and amplification between its input and output signal ports and is intended for use in high-speed communication systems. The low noise ASNT6121 can process an up to 43Gbps data signal and deliver a limited 600mVp-p differential signal for single ended input current levels as low as 80μA. Automatic offset control (AOC) is included to adjust the indirect input signal port to compensate for the average value of the photodiode current on the direct input port and any internal DC offsets. AOC’s low frequency corner is 5.0KHz with an off chip capacitor value of 100nF. The part’s output supports the CML logic interface with on chip 50Ohm termination and may be used differentially, AC/DC coupled, single-ended, or in any combination. It operates from a single +3.3V power supply and includes a temperature sensor.
