Digital FM IR Receiver + Speaker driver

Overview

STAR2030 is a digital FM IR receiver ASIC with stereo PDM H-bridge headphone drivers. The embedded digital FM demodulator supports 4 stereo audio channels: A(2.3MHz/2.8MHz), B(3.2MHz/3.8MHz), C(4.3MHz/4.8MHz) and D(5.2MHz/5.7MHz).

It is fully configurable by an external MCU through an SPI interface. A four-pin bidirectional I2S master may be configured to pass audio through an external DSP for effects processing
