【HEDS Encoder Evaluation Board】

Broadcom's HEDS series encoder evaluation boards are the ideal choice for precision motion control applications. Based on reflective optical encoder technology, these boards provide high-accuracy solutions for motor control and position detection.

The HEDS-9930 evaluation board exemplifies this, serving as a reference design for the AEDR-9930 encoder ASIC. The AEDR-9930E2/E2L is a three-channel reflective optical encoder that employs reflective technology to generate digital signals. These digital encoders provide dual-channel (AB) quadrature digital outputs alongside a third-channel digital index output, enabling precise detection of position, velocity, and direction.

Typical application scenarios for this evaluation board span multiple domains:

Closed-loop stepper motors for enhanced precision control

Industrial printers for improved print accuracy and stability

Robotics for precise motion control

Pan-tilt-zoom (PTZ) cameras for smooth motion tracking

Portable medical devices meeting high-precision diagnostic requirements

【Optical Sensor Evaluation Board】

Broadcom demonstrates formidable technical prowess in optical sensor evaluation boards, with the BK7258 AI SoC Evaluation Board standing as a prime example. This highly integrated Wi-Fi 6 + Bluetooth 5.4 low-power audio-video SoC chip achieves robust AI capabilities through hardware acceleration, algorithm optimisation, and ecosystem integration.

Core AI functionalities of the BK7258 include:

Dedicated AI Processing Unit: Integrates an efficient AI accelerator supporting on-device execution of complex AI computations (e.g., CNN convolutional neural networks). Enables tasks such as image recognition and speech processing without cloud dependency, achieving typical application latency below 200 milliseconds.

Computer vision capabilities: Supports 720p@25fps image capture, MJPEG hardware encoding, and JPEG codec processing. Integrated image rotation/scaling modules enable facial recognition and gesture/motion capture functionality.

Voice interaction system: Dual-microphone noise reduction technology incorporates built-in ambient noise suppression (ANS) and acoustic echo cancellation (AEC) algorithms to enhance voice capture clarity in noisy environments.

Low-power architecture: Utilises 22nm process technology, with service-preserving power consumption below 150μA, deep sleep mode at just 16μA, and shutdown mode as low as 2.5μA, making it highly suitable for battery-powered devices

【Ethernet Adapter Evaluation Board】

Within the high-speed networking domain, Broadcom's Tomahawk series Ethernet adapter evaluation boards demonstrate industry-leading technical prowess. The Tomahawk Ultra Ethernet Switch Evaluation Board supports ultra-low latency, high throughput, and lossless operation, specifically engineered for Ethernet switching in demanding technical environments.

Key Features of Tomahawk Ultra:

Ultimate Performance: Achieves 51.2ns switching latency at 250Tbps throughput, supporting line-rate switching of packets as small as 64 bytes and processing up to 7.7 billion packets per second

Lossless Architecture: Implements Link Layer Retry (LLR) and Credit-Based Flow Control (CBFC) to eliminate packet loss and ensure reliable data transmission

AI Cluster Optimisation: When deployed with Scalable Ethernet (SUE), achieves sub-400ns XPU-to-XPU communication latency, setting a new benchmark for large-scale, tightly synchronised AI computations
