1ghz Transimpedance Preamplifier With 25db Dynamic Range Integrated Products

The MAX3260 high-speed Transimpedance Amplifier is ideally suited for Fibre Channel and SDH SONET appli- cations. An extended dynamic range makes the MAX3260 useful in optical receiver systems with as much as 25dB of input signal range. A DC-restore feed- back network prevents Amplifier saturation in all Fibre Channel applications by allowing input currents as high as 900A to be amplified linearly. To reduce noise, the restore function is disabled at low input levels, allowing detection of signals as small as 2.4A with a signal-to- noise ratio of 10. The Filter output (FILTER) of the MAX3260 provides a convenient voltage source for a Photodiode especially when the circuit will be placed into a TO-style header with the Photodiode The Filter output is connected to VCC through a 1k on-chip resistor. In combination with a bypass capacitor, the Filter function significantly reduces the amount of noise present at the cathode of the Photodiode The MAX3260 operates from a single +5V supply con- suming only 115mW of power when the output is AC coupled. With 50 output termination, it consumes less than 300mW of power. By Maxim Integrated Products
