2.1 Fully Compatible Parts Among the Three

The specifications of the three products are consistent in the following dimensions, forming the technical basis for interchangeability:

2.1.1 Hardware Interface Layer

PCB dimensions are identical (167.65mm × 111.15mm)

PCIe 3.0 ×8 bus (same link width and speed)

4× Micro-BNC CXP-12 connectors

HD DB26 D-sub front panel I/O connector

6-pin PEG auxiliary power connector

4 GB DDR4 on-board memory

Typical power consumption ~17W

2.1.2 CXP Protocol Layer

All 7 levels of downstream speeds (CXP-1 to CXP-12)

All 2 levels of upstream speeds (20.83 / 41.66 Mbps)

Maximum aggregate bandwidth of 50 Gbps

Maximum of 4 cameras

Area scan + line scan cameras

Full range of Mono / Bayer / RGB / RGBA 8~16bit formats

2.1.3 Basic I/O Layer

Polarity control

Noise filtering

2.1.4 Software Standard Layer

All support GenICam and GenTL standards

All support Windows 10/11 and Linux x86-64

2.2 Unique Capabilities of StarTest

2.2.1 FPGA Open Platform

This is StarTest's core differentiated capability and the most fundamental difference from Euresys and KAYA.

Euresys's FPGA provides fixed firmware functions, and users can only customize within the limited CustomLogic framework. KAYA does not open the FPGA at all, and users cannot modify any underlying logic. In contrast, StarTest provides a complete FPGA project, allowing users to add custom logic. Although the source code of the CXP Host IP is not provided, users can fully understand and call its interfaces through rich documentation and usage examples.

This model is similar to the IP core licensing method of Xilinx/AMD — the IP core itself is closed-source, but users can freely integrate and extend it in a complete project environment. For customers with FPGA development capabilities, this means they can implement custom image preprocessing algorithms, edge AI inference, custom I/O control logic, etc., on the frame grabber, which cannot be provided by Euresys and KAYA.

2.2.2 Complete Product Ecosystem — More Than Just a PCIe Card

This comparison only involves StarTest's PCIe-1004 product. In fact, StarTest has a complete product matrix covering from embedded to desktop, from standard CXP to CXP Over Fiber, and from digital to analog:

Product Positioning
PCIe-1004 PCIe Desktop Platform, CXP-12 ×4, FPGA Open Project
Jetson Series Boards Nvidia Jetson Embedded CXP Acquisition
Z19 (Zynq Embedded Platform) ARM + FPGA SoC, Standalone Operation, No Host PC Required
PCIe-3004 100G CXP Over Fiber Frame Grabber
CXP Over Fiber Adapter Board CXP ↔ Fiber Conversion, Extend Transmission Distance
PCIe-1005 CXP Analog Image Frame Grabber

2.2.3 Open Source Software Stack — No Vendor Lock-in

Based on Aravis (Open Source GenICam Implementation):

Users can audit the underlying driver code

Can freely switch to other compatible hardware

Research users can deeply customize the software stack

Naturally meets the requirements of independent innovation/domestic substitution

2.2.4 Domestic Independent Controllability

In sensitive fields such as military industry, aerospace, and government, this is an irreplaceable advantage.
