CMX618 & CMX638 RALCWI™ Vocoder ICs

CML Micro CMX618 and CMX638 RALCWI™ Vocoder ICs are flexible, high integration, high performance, digital voice products, offering near toll-quality voice at very low bit rates. The CMX618 is a half-duplex vocoder, and the CMX638 is full-duplex. Both devices feature an integrated voice CODEC, offering a complete analog voice to low bit rate vocoded data functions, with integrated channel filters removing the need for external components. A Forward Error Correction (FEC) engine provides optimum performance in real-life applications. These devices operate from a dual power supply (1.8V and 3.3V) and are available in both 48-pin LQFP (L4) and 48-pin VQFN (Q3) packages.
