FAQ

What is the maximum DDR4 speed supported by the LX2162RN82029B?

The LX2162RN82029B supports a single 72-bit DDR4 interface running at 2.9 GT/s, corresponding to DDR4-2900 operation with full JEDEC compliance. This enables sustained memory bandwidth exceeding 23 GB/s with ECC protection, critical for DPAA2 packet buffering and real-time forwarding in high-throughput network appliances.

Does the LX2162RN82029B support IEEE 1588 Precision Time Protocol?

Yes, the LX2162RN82029B includes hardware-accelerated IEEE 1588 timestamping across all supported Ethernet MACs. It implements a full PTP boundary clock with sub-50 ns timestamp resolution, enabling precise synchronization in 5G fronthaul, TSN bridges, and telecom infrastructure without external timing ICs.

How many PCIe Gen3 lanes does the LX2162RN82029B provide?

The LX2162RN82029B integrates three independent PCIe Gen3 controllers configured as x8, x4, and x4 - totaling 16 lanes. These are electrically isolated and can be assigned to discrete peripherals such as FPGA accelerators, NVMe SSDs, or 10G/25G Ethernet adapters without bandwidth contention.

Is hardware virtualization supported on the LX2162RN82029B?

Yes, the LX2162RN82029B incorporates Arm MMU-500 to enforce hardware virtualization and partitioning. This enables secure co-location of multiple OS instances - for example, separating Linux-based control plane from real-time DPAA2 data plane - with guaranteed memory isolation and interrupt routing integrity.

What security features are integrated into the LX2162RN82029B?

The LX2162RN82029B includes QorIQ Platform Trust Architecture 3.0 with 256 KB on-chip RAM for trusted execution, secure boot with cryptographic signature verification, TrustZone-enabled peripheral access control, and hardware-accelerated cryptography (SEC engine) supporting AES-GCM, SHA-2, and RSA up to 4096-bit keys.
