Transimpedance amplifier (TIA) with current monitor 1 - 4 Gbps
Vitesse Semiconductor
The VSC7970 is a high performance transimpedance amplifiers (TIA) for Ethernet, Fibre Channel and SONET applications. It features a 5 kΩ differential transimpedance and 1.8 GHz bandwidth with source-terminated differential outputs. It has a linear current monitor, adding diagnostic capabilities, and simplifying optical alignment during the manufacturing process. A space saving filter connection provides for positive bias to the photodetector through an on-chip 500 resistor to VCC, allowing for easy assembly on a TO-46 header.
