1.3 Introduction to the CRD48L10 Kit
Figure 1-1. CRD48L10-4in4out Block Diagram
The main components to be familiar with on the board are:
• CS48L10 DSP
• CS42L73 Ultra Low-power CODEC
• CS35L01 Mono Class-D Amplifier
• CS8416 S/PDIF Rx
• CS8406 S/PDIF Tx
• Silicon Labs ™ C8051F930 MCU
The main purpose of this board is to allow a customer to evaluate the Cirrus Logic CS48L10 DSP and other Cirrus Logic
analog semiconductors in a complete audio subsystem.
The Silicon Labs MCU handles the SPI, I²C, and GPIO to control the board components. USB control of the DSP is
possible by connecting the CDB-MCU-DEBUG dongle to the JP2 header.
