Introduction
The Terasic HSMC-NET is a Gigabit Ethernet transceiver with a High Speed Mezzanine Connector
(HSMC) interface. It offers network transfers of up to 1 Gbps with the host board using a HSMC
connector. Also, it provides a fully integrated Ethernet solution enabling fast implementation design,
shortening development times, and allows you to focus on the core functions of the system design.
Lastly, the HSMC-NET can be connected any HSMC/HSTC interfaces.
