1 to 4 Gbps TIAs
1 to 4 Gbps Transimpedance Amplifiers with Photocurrent Monitor
GENERAL 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.
