The VSC7809, a wide band, 3.3 V integrated photodetector and transimpedance amplifier
The VSC7809, a wide band, 3.3 V integrated photodetector and transimpedance amplifier (TIA) offers high responsitivity, sensitivity and large optical active area. The amplifier allows for easy alignment and is suitable for demanding functions, such as small form factor optoelectronic modules.

The wide bandwidth of the device allows for operation at 1.0 Gb/s or 1.25 Gb/s, making it compliant for either Fibre Channel or Gigabit Ethernet applications. It integrates both the optical detector and the amplifying functions on the same IC, reducing overall board space requirements. This high level of integration improves system reliability and manufacturing yield. Central among its advantages are a high Power Supply Rejection Ratio (PSRR) and very low jitter. Both of these benefits provide performance augmentations in small form factor optical modules.

The amplifier uses a single 3.3 V supply and is delivered in a TO-46 package. It is also available in bare die form.
