Semtech GN2033

Thunderbolt™ Cable Transceiver

Featuring sophisticated signal conditioning capability, Gennum's in-connector Thunderbolt™ transceiver technology delivers reliable data transfer at cutting-edge speeds over low cost, thin-gauge copper cables.

The GN2033 is a tiny, low power transceiver chip designed to be placed inside the connectors at either end of a Thunderbolt™ cable, enabling dual bidirectional 10Gb/s concurrent links over narrow-gauge copper wires. Unlike ordinary passive cables that can be used at lower data rates, the unprecedented speed of the new Thunderbolt™ technology places unique demands on the physical transmission media. The GN2033 provides the sophisticated signal boosting and detection functions required to transfer high-speed data without errors across inexpensive Thunderbolt™ copper cables.
