CMX639D4数据手册集成电路（IC）的编解码器规格书PDF

描述 Description

Brief Description
The CMX639 is a Continuously Variable Slope Delta Modulation (CVSD) full duplex CODEC for use in consumer and commercial digital voice communication systems. With its robust and selectable coding algorithms, low cost, very low power, and small size, the CMX639 is ideal for use in a wide variety of consumer and business digital voice applications. Its completely integrated CODEC simplifies design and eliminates the costs, complexity and risk of external filters and software algorithms.
