Introduction
The EVM is intended for evaluating AFE4403 device. The family of devices consist of a low-noise receive
channel, the LED transmit section, and diagnostics for sensor and LED fault detection. The AFE4403 has
a highly configurable timing controller, enabling complete control of the device’s timing characteristics. The
device also has an integrated oscillator working off from two clock sources: either an external crystal or
the clock from an external host processor to ease clocking requirements and provide a low-jitter clock to
the AFE4403 The device communicates to an external host processor using the Serial Peripheral Interface
(SPI). The purpose of the EVM is to expedite evaluation and system development activities related to
AFE4403 devices. The demonstration kit is shown in
