【Analogue Switch Evaluation Board】
Analogue switches serve as the “traffic hub” connecting critical modules such as sensors, amplifiers, and data converters, with their performance directly impacting signal integrity and system accuracy. Renesas' evaluation board enables designers to intuitively assess switch chip performance in real-world conditions.

Core Advantages and Typical Design:
These evaluation boards are typically built around Renesas' high-performance analogue switches or multiplexer (MUX) ICs. The on-board design focuses on minimising parasitic effects and signal path losses, ensuring accurate results when evaluating critical parameters such as bandwidth, on-resistance, off-isolation, and distortion. For instance, many evaluation boards offer multiple input/output connection options (such as SMA connectors, header pins, etc.) and provide critical filter, matching, and termination resistor pads. This facilitates user configuration and optimisation for specific applications, including audio routing, instrumentation, and automated test equipment.

【Crosspoint Switch Evaluation Board】
Crosspoint switches establish arbitrary connections between multiple inputs and outputs, serving as core components for complex signal routing systems. They find extensive application in professional video processing, broadcast systems, and security surveillance.

Representative Product: HA456EVAL1 Evaluation Board
Renesas' HA456EVAL1 evaluation board provides an ideal platform for assessing the 8x8 video crosspoint switch HA456. This board vividly demonstrates how highly integrated switch chips can be applied in practical systems.

Powerful Core: The HA456 chip on the evaluation board integrates a digitally controlled matrix comprising 64 fully buffered switches, enabling any or all of the 8 video input signals to be routed to any output. Each output features a high-speed (200V/µs slew rate), unity-gain buffer capable of directly driving video loads.

Convenient Evaluation: This platform provides a complete 8x8 video switcher simulation environment with straightforward configuration, supporting standard 75Ω video setups. A key feature is its compatibility with PC software control, enabling rapid channel switching and configuration testing. Furthermore, optional adapters (HA456/7EVAL3) allow manual control without a PC, significantly enhancing testing flexibility.

【USB Switch Evaluation Board】
With the proliferation of high-speed interfaces such as USB and PCIe across consumer electronics, computing, and industrial sectors, switches dedicated to managing and switching these data flows have become critical. Renesas' evaluation board assists designers in addressing challenges including multi-host device switching, signal integrity, and protocol compatibility.

Core Functions of Evaluation Boards:
These boards typically evaluate USB switches, multiplexers, or hub controllers. PCB layout and impedance control are strictly designed to USB specifications for signal integrity assessment. On-board capabilities may include:
Multi-port Switching: Demonstrates intelligent switching logic between multiple USB hosts or devices.
Protocol support verification: Testing compatibility with USB 2.0, USB 3.x, and even USB Type-C and Power Delivery (PD) protocols.
System integration testing: Providing interfaces for connection to a host MCU to facilitate embedding custom control logic.
