DC-SCM LVDS Tunneling Protocol and Interface IP Core

Compliant with OCP DC-SCM 2.0 and Aggregate Multiple Data Channel

The Lattice Semiconductor DC-SCM LVDS Tunneling Protocol and Interface (LTPI) IP Core is an Open Computer Project (OCP) Data Center – Secure Control Module (DC-SCM) Standards compatible solution which is introduced in the DC-SCM 2.0 Specification. DC‑SCM aims to move common server management, security and control features from a typical motherboard into a module designed in different form factors (horizontal, vertical). The basic idea is to enable a common security and management module form and interface which can be used across datacenter platforms.

DC-SCM LTPI IP Core provides a solution for minimal wire connection between two FPGAs to provide TDM-based bidirectional communication, aggregating multiple data such as I2C, GPIO and UART to add more flexibility to a customer’s system and board design. This solution is compliant with Datacenter-ready Secure Control Module (DC-SCM) 2.0.

Multiple interfaces tunneling – Supports tunneling of more interfaces such as GPIO, I2C, UART, OEM, and data channel aggregation.

High bandwidth capabilities – Supports up to 800 Mbps LVDS data rate for MachXO3™ family devices.


  • Compliant with OCP DC-SCM 2.0 LTPI 1.0 Specifications
  • Supports Link initialization, discovery, and negotiation
  • Supports Multi-channel Serial Interface and LVDS
  • Supports up to five channels aggregation/disaggregation in total
  • Supports GPIO, I2C, UART, OEM, and Data channel aggregation

Note: Utilization data is generated using a sample IP configuration for LCMXO3L-9400C-6BG484C with Strategy set to default setting.
Number may vary when using a different software version or targeting a different device density, synthesis tool, or speed grade. For Static Timing Analysis, IP is tested in both -5 and -6 speed grade. For better performance in certain cases, user is recommended to run multiple iterations of Place and Route and/or set Optimization Goal to Timing in Strategy Section of SW tool.
