Edited by (http://www.seekic.com/),the leading IC purchasers' best choice of platform for one-stop valued service!
Description:
The VSC7773, VSC7970, VSC7971, VSC7972, and VSC7973 are high performance Transimpedance Amplifiers (TIA) for Ethernet, Fibre Channel and SONET applications. The VSC7773 support rates from 1 Gbps to 4.25 Gbps. The other parts support rates up to 2.5 Gbps. They feature 5 kΩ differential transimpedance and 1.8 GHz bandwidth with source-terminated differential outputs. All five parts have a linear current monitor, adding diagnostic capabilities, and simplifying optical alignment during the manufacturing process. A space saving filter connection is provide for positive bias to the photodetector through an on-chip 500Ω resistor to VCC, allowing for easy assembly on a TO-46 header.
Features:
·Single +3.3 V Supply
·5 kΩ Differential Transimpedance
·Low Power Consumption for SFP/SFF Applications
·Differential Outputs with Linear Current Monitor
·Available as Bare Dice or in a 4-pin or 5-pin TO-46 Package |
