LVDS Tunneling Protocol and Interface

The MAX® 10 devices support LVDS Tunneling Protocol and Interface (LTPI) soft IP in the Quartus® Prime software, specifically targeting data center applications.

The Datacenter - Secure Control Module (DC-SCM) 2.0 specification introduces LTPI and offers higher bandwidth and better scalability compared to the serial general purpose I/O (SGPIO) interface. The LTPI interface is designed to tunnel various low-speed signals (such as GPIO, I2C, UART, data, and OEM) between the Host Processor Module (HPM) and Secure Control Module (SCM). The LTPI protocol operates over the low voltage differential signaling (LVDS) electrical interfaces.
