FAQ

What is the maximum supported DDR4 data rate for XCKU085-1FLVA1517I?

The XCKU085-1FLVA1517I supports DDR4 memory interfaces at up to 2400 MT/s across two independent 64-bit channels. This delivers 38.4 GB/s aggregate bandwidth, validated with JEDEC-compliant DIMMs and onboard termination. The controller includes write leveling, read/write leveling, and per-bit deskew calibration to ensure signal integrity at full rate. XCKU085-1FLVA1517I implements these features in hardened logic, reducing timing closure risk versus soft IP alternatives.

Does XCKU085-1FLVA1517I support partial reconfiguration?

Yes, XCKU085-1FLVA1517I fully supports partial reconfiguration through Vivado Design Suite tools and runtime drivers. It enables dynamic swapping of logical partitions-such as modulators, demodulators, or filter banks-without resetting the entire device. This capability is used in radar systems to adapt waveform processing on-the-fly. XCKU085-1FLVA1517I implements dedicated configuration port logic and frame-based bitstream addressing to guarantee deterministic reconfiguration latency under 100 µs.

What transceiver protocols are natively supported by XCKU085-1FLVA1517I?

XCKU085-1FLVA1517I natively supports PCIe Gen3 x16, 100G Ethernet (KR4/CR4), CPRI, and JESD204B/C via its GTY transceivers and hardened MAC blocks. Protocol compliance is achieved through integrated PCS layers and auto-negotiation state machines-not soft logic. XCKU085-1FLVA1517I also supports PAM4 signaling at 48.8 GT/s, enabling next-gen 200G/400G fronthaul links when paired with appropriate PHYs.

What is the thermal design power (TDP) of XCKU085-1FLVA1517I?

The XCKU085-1FLVA1517I has a typical thermal design power of 32 W under representative radar processing workloads, with a maximum junction temperature rating of 100°C. Power estimates are derived from AMD's XPE tool using actual placed-and-routed designs with DDR4, GTY, and DSP usage profiles. XCKU085-1FLVA1517I includes on-die thermal sensors and dynamic power gating to maintain safe operation in conduction-cooled avionics chassis.

Is XCKU085-1FLVA1517I qualified for extended temperature operation?

Yes, XCKU085-1FLVA1517I is rated for industrial temperature range (–40°C to +100°C junction), with qualification per AEC-Q100 Grade 3 and extended reliability testing for aerospace applications. It undergoes burn-in, HTOL, and ESD testing per JESD22 standards. XCKU085-1FLVA1517I is commonly deployed in UAV flight controllers and satellite payload processors where ambient temperatures exceed 85°C and radiation tolerance is required.
