**MicroChip FPGA Board Passes CoaXPress Interface Tests – Breakthrough in Video Capture**
**Introduction**
MicroChip Technology announced today that its VIDEO‑DC‑CXP FPGA‑based frame grabber has successfully cleared the rigorous CoaXPress (CXP) interface compliance tests. The achievement marks a significant step forward for high‑speed industrial vision systems, where reliable data transfer and low latency are non‑negotiable. Engineers at MicroChip’s embedded solutions lab subjected the board to a battery of stress tests, including multi‑lane CXP‑6 operation, error‑correction verification, and thermal cycling, all of which it passed without deviation from the standard.
**Key Developments**
The VIDEO‑DC‑CXP board integrates a Xilinx Kintex‑7 FPGA with a PCIe‑1004 host interface, delivering four independent CXP channels each capable of 12.5 Gbps. This configuration enables simultaneous acquisition from multiple high‑resolution sensors, a capability that was previously limited to proprietary or FPGA‑only designs. Notable technical highlights include:
- **Deterministic latency** under 2 µs from sensor to host memory, critical for real‑time inspection.
- **On‑board preprocessing** (pixel formatting, region‑of‑interest extraction) performed in FPGA logic, reducing CPU load.
- **Robust error handling** with built‑in CRC and retransmission mechanisms that maintained zero packet loss during extended 24‑hour soak tests.
- **Compact form factor** (half‑length, low‑profile) that fits into standard 1U rack‑mount chassis, easing integration into existing machine‑vision platforms.
**Industry Analysis**
Industry analysts note that the CoaXPress standard has gained traction as the preferred interface for high‑bandwidth, long‑reach camera links, especially in sectors such as semiconductor inspection, food sorting, and autonomous vehicle testing. The ability to combine CXP’s rugged cabling with an FPGA‑centric frame grabber addresses two persistent pain points: cable‑induced signal degradation and host‑processor bottlenecks. MicroChip’s solution positions itself competitively against established players like Teledyne DALSA and Basler by offering a programmable logic layer that can be tailored to specific algorithms without redesigning hardware. |
