该AFE44x0SPO2EVM用于评估AFE4400和AFE4490设备。该系列器件是完全集成的AFE非常适合脉搏血氧仪的应用和包括低噪声接收通道,LED的发射部分和诊断传感器和LED故障检测。DescriptionThe AFE44x0SPO2EVM is intended for evaluating AFE4400 and AFE4490 devices. The family of devices are fully integrated AFE ideally suited for Pulse Oximeter applications and consist of low noise receive channel, the LED transmit section and diagnostics for sensor and LED fault detection. The AFE4400/AFE4490 has very highly configurable timing controller enabling the user to have complete control of the device’s timing characteristics. The device also has an integrated oscillator working off an external crystal to ease clocking requirements and provide a low jitter clock to the AFE44x0. The device communicates to an external host processor using the Serial Peripheral Interface (SPI).The purpose of the AFE44x0SPO2EVM is to expedite evaluation and system development activities related to AFE44x0 devices.
