High speed serial link
Appearance
High Speed Serial Link (HSSL) is a proprietary communications protocol and was primarily developed by Alcatel. It is now owned by Alcatel-Lucent.
Capable of transmitting data at rates up to 10 Gbit/s, HSSL is chiefly used in electronic system backplanes for inter-board communication.
Xilinx, among other integrated circuit vendors, currently supports the standard.
