FAQ

What is the maximum DDR4 data rate supported by the LX2160SE72232B?

The LX2160SE72232B supports DDR4-3200 operation, delivering 3.2 GT/s per pin across dual 72-bit interfaces. This translates to 51.2 GB/s aggregate bandwidth with full ECC protection. The device requires strict PCB layout adherence to JEDEC DDR4 specifications, including fly-by topology and on-die termination calibration sequences executed during boot.

Does the LX2160SE72232B support IEEE 1588 hardware timestamping on all Ethernet MACs?

Yes, the LX2160SE72232B provides full hardware timestamping capability on all 18 integrated Ethernet MACs, with sub-50 ns resolution and support for IEEE 1588-2008 (v2) profiles. Timestamp registers are accessible via memory-mapped I/O, and the PTP clock domain is synchronized to the system reference clock with jitter below 1 ps RMS.

How many PCIe Gen3 lanes does the LX2160SE72232B provide, and how are they allocated?

The LX2160SE72232B offers five PCIe Gen3 controllers: one x8 and four x4 configurations, totaling 24 lanes. These are drawn from its 24 SerDes lanes and can be dynamically allocated via strap pins and firmware configuration. No external switch is needed for common topologies like dual 10G NICs + NVMe storage + FPGA co-processor.

Is the LX2160SE72232B pin-compatible with other QorIQ LX family members like the LX2120A?

No, the LX2160SE72232B is not pin-compatible with the LX2120A or LX2080A. Although all share the same 1517-ball FC-PBGA package, ball assignments differ significantly-especially for DDR, SerDes, and power domains-to accommodate the LX2160A's higher core count, larger cache, and enhanced I/O bandwidth.

What security features are implemented in hardware on the LX2160SE72232B?

The LX2160SE72232B integrates QorIQ Platform Trust Architecture 3.0, including a 256 KB on-chip secure RAM, hardware root-of-trust with immutable boot ROM, secure boot flow with SHA-256/ECDSA verification, TrustZone-enabled memory isolation, and tamper-resistant key storage. All cryptographic operations execute inside the SEC engine without exposing keys to main memory.
