1.1. Features
The Interlaken (2nd Generation) Intel FPGA IP has the following features:
- General features:
- Compliant with the Interlaken Protocol Specification, Revision 1.2.
- Supports 4, 6, 8, 10, and 12 serial lanes in configurations that provide up to 318.75 Gbps raw bandwidth.
- Supports per-lane data rates of 6.25, 10.3125, 12.5, 25.28, 25.78, 25.78125, and 53.125 Gbps using Intel FPGA on-chip high-speed transceivers.
- User interface features:
- Supports dynamically configurable BurstMax and BurstMin values.
- Supports Packet mode and Interleaved mode for user data transfer.
- Supports up to 256 logical channels in out-of-the-box configuration.
- Supports multi-segment user interface.
- Flow-control features:
- Supports optional out-of-band flow control blocks.
- Supports optional user-controlled in-band flow control with 1, 2, 4, 8, or 16 16-bit calendar pages.
- Supports error correction code (ECC) for memory block implementation with the IP.
- Line-side features:
- Supports per-lane data rate of 53.125 Gbps using pulse amplitude modulation (PAM4) mode in E-tile variations.
- Supports per lane data rates of 6.25, 10.3125, 12.5, 25.28, 25.78, and 25.78125 Gbps using non-return-to-zero (NRZ) mode in E-tile variations.
- PHY features:
- Supports PMA adaptation.
- Interlaken Look-aside mode:
- Supports per lane data rates of 6.25, 10.3125, 12.5, 25.28, 25.78 and 25.78125 Gbps using NRZ and 53.125 Gbps using PAM4 mode in E-tile variations.
- Supports packet mode for user data transfer.
- Available only in Intel® Stratix® 10 and Intel® Agilex™ 7 E-tile device variations in current version of the Intel® Quartus® Prime software release.
Note: Contact Intel Support to request Interlaken Look-aside mode access in IP variations that target an Intel® Stratix® 10 H- and L-tile device.
