WOLF-3185
Overview
High-Density 4K Video Capture and Conversion with FGX2
The WOLF-3185 provides a high data rate, high density video capture and transmit platform with the FGX2, WOLF’s second-generation frame grabbing technology. FGX2 is a 4K-capable digital and analog frame grabber with conversion and transmit capability, built on the Xilinx® Kintex® UltraScale+™ series of FPGA devices. It is ideally suited for machine vision or sensor data processing applications deployed in harsh environments where low latency matters and SWaP is at a premium.
This module’s ICD aligns with ANSI/VITA 46.9 for 3U and 6U VPX configurations. It provides an excellent upgrade path from the previous generation WOLF-3080 with a compatible hardware ICD and thermal envelope. This module can be paired with a module powered by an NVIDIA GPU to provide extremely low latency peer-to-peer communication that will reduce the host system CPU overhead, which can be critical when processing large amounts of data.
MCOTS options include the ability to change interfaces to other analog or digital video standards. RTOS drivers are optionally available upon request.
Block Diagram
The block diagram illustrates an FGX2 XMC focused on high-density video capture/conversion, highlighting the PCIe x8 host interface and the low-latency streaming paths to peer GPU modules. It emphasizes multiple SDI-class I/O channels and DP ingest paths (where configured) used to move video with sub-frame latency for downstream processing.

FAQ
Choose WOLF-3185 when you want an FGX2-based XMC optimized for a balanced mix of SDI I/O plus DisplayPort ingest, without the complexity of maximum channel density.
This module is a strong fit for:
- Machine vision or sensor ingest pipelines that use a mix of SDI and DP ingest
- Low-latency capture/conversion where SWaP is constrained
- Designs that want an upgrade path from earlier FGX-family modules with similar ICD/thermal behavior
If your program requires the highest SDI/ARINC channel counts (e.g., 8-in/8-out classes), a higher-density FGX2 module is typically the better fit.
It is intended to enable low-latency data exchange with an NVIDIA GPU while reducing host CPU overhead.
In practice this can matter when:
- You are streaming multiple high-rate channels and CPU copies become a bottleneck
- You want sub-frame latency pipelines from capture → processing → output
- You want to pair FGX2 with a GPU module and treat the system as a tightly coupled pipeline
Net: GPUDirect capabilities can shift the architecture from host-centered buffering to a more efficient capture-to-processing path.
Confirm these early because they impact whether the module meets throughput and software requirements:
- PCIe interface: PCIe Gen3 x4—ensure your expected channel count/bitrate fits within that host bandwidth.
- I/O mix: up to four SDI inputs and outputs plus two DisplayPort (MST) inputs (each DP input can carry multiple streams).
- Optional capabilities: ARINC 818 I/O, CoaXPress input, CVBS/RGsB input, DP-to-SDI conversion in FGX2 (option).
- Software baseline: Linux/Windows drivers are supported; VxWorks RTOS drivers are optional.
If your architecture depends on RTOS support, treat that as an ordering-time requirement, not an afterthought.
Key ordering-time decisions typically include:
- XMC connector selection (XMC 2.0 variants) and carrier compatibility
- I/O configuration: SDI speed/channel mix (3G vs 12G where applicable), DP ingest configuration, and optional DP-to-SDI conversion
- DDR4 option: optional onboard DDR4 for additional application support
- RTOS drivers: VxWorks option if required
- Program controls: conformal coatings and variant locking
