The LTPI Reference Design provides multiple solution templates that use the current LVDS Tunneling Protocol Interface (LTPI) IP. Originally developed to the Datacenter-ready Secure Control Module (DC-SCM) 2.0 LTPI specification, the IP has since been updated to comply with DC-SCM 2.2, incorporating a standardized Datacenter-ready Secure Control Interface (DC-SCI). This IP aggregates multiple data channels such as I2C, GPIO, and UART to add more flexibility to a customer's system and board design.
One of the significant changes in the DC-SCM 2.0 specification is the introduction of Low-voltage differential signaling Tunneling Protocol & Interface (LTPI). The LTPI addresses shortcomings of the Serial GPIO interface used in DC-SCM 1.0.
