Brief Description 

 

This document details the use of two Evaluation Kits: EV6180 for CMX608 and CMX618, EV6380 for 
CMX638. The EV6180 and EV6380 Evaluation Kits each provide the means to demonstrate and evaluate 
the operation of CMX6x8 RALCWI Vocoder ICs. The boards are operated from a single, ex5Vdc 
power supply. On-board voltage regulators provide the required analogue and digital supply voltages. 

Each board can be controlled with a PE0003 Evaluation Kit Interface Card and ES0003 GUI software. To 
use this software, a host PC and PE0003 Evaluation Kit Interface Card are required. Additionally, an 
external audio CODEC is required to demonstrate the CMX608 option (EV6180). 

Connectors are provided to allow direct interfacing to the C-BUS and SPI interfaces on the CMX6x8 
devices. The on-chip audio CODEC (CMX618/638 devices only) is accessible through two 3.5mm stereo 
jack sockets. The audio CODEC signal paths can be configured as single-ended or differential.
