FAQ

What is the maximum DDR4 data rate supported by the LX2160XC72232B?

The LX2160XC72232B supports DDR4 SDRAM at up to 3.2 GT/s across two independent 72-bit channels with full ECC. Each channel operates with differential clocking and on-die termination, enabling reliable operation in high-density memory subsystems used in telecom and datacom equipment. The LX2160XC72232B implements JEDEC-compliant DDR4 timing parameters including tRCD, tRP, and tRFC for LPDDR4-compatible configurations.

Does the LX2160XC72232B support PCIe Gen4?

No, the LX2160XC72232B supports PCIe Gen3 only - with two 8-lane controllers and four 4-lane controllers, all compliant with PCI Express Base Specification Revision 3.1. It does not implement Gen4 PHY or data-link layers. Designs requiring Gen4 must use alternative processors such as NXP's later LX22xx series or competitor offerings. The LX2160XC72232B's SerDes lanes are optimized for Ethernet and SATA 3.0, not PCIe Gen4 signaling.

How many Ethernet MACs does the LX2160XC72232B integrate, and what speeds do they support?

The LX2160XC72232B integrates 18 Ethernet MACs supporting speeds from 1G to 100G via multiple physical layer interfaces: SGMII, XFI, SFI, USXGMII, CAUI-4, 50GAUI-2, and 25G-AUI. These MACs are fully IEEE 1588 v2-compliant with hardware timestamping engines accurate to ±25 ns. The LX2160XC72232B routes MAC traffic through its DPAA2 switching fabric, enabling non-blocking 114 Gbps L2 switching capacity.

Is the LX2160XC72232B pin-compatible with other Layerscape LX devices like the LX2120A or LX2080A?

Yes, the LX2160XC72232B shares the same 1517-ball FC-PBGA package and pinout with the LX2120A and LX2080A. Differences between models are configured via TEST_SEL_B and cfg_svr[0:1] pins during power-on reset, allowing board-level reuse across performance tiers. This enables scalable hardware design where the same PCB can host LX2080A, LX2120A, or LX2160XC72232B based on firmware and thermal constraints.

What security features are implemented in hardware on the LX2160XC72232B?

The LX2160XC72232B implements QorIQ Platform Trust Architecture 3.0, including Arm TrustZone, secure boot with immutable ROM-based root-of-trust, 256 KB on-chip SRAM for trusted firmware execution, battery-backed tamper detection, and hardware cryptographic accelerators (SEC) supporting AES-GCM, SHA-2, RSA-4096, and ECC. All security functions are accessible via standardized APIs in the Layerscape SDK, and the LX2160XC72232B enforces isolation between secure and non-secure worlds using Arm MMU-500.
