Functional Description

The VSC8021 and VSC8022 are high-speed SONET interface devices capable of handling serial data at rates up to 2.5Gb/s. These devices can be used for STS-3 through STS-48 SONET applications.

These products are fabricated in gallium arsenide using the Vitesse H-GaAs™ E/D MESFET process which achieves high-speed and low power dissipation. These products are packaged in a ceramic 52-pin leaded ceramic chip carrier.
