Description

The MSM7602-001 is an electronic component model in the IC Chips product category. It is an improved version of the MSM7520 with similar configuration and features. The MSM7602 uses a 19.2 MHz clock frequency and operates at a power supply voltage range of 2.7 V to 5.5 V. It is designed to cancel echo in acoustic systems or telephone lines by estimating the echo path and generating a pseudo echo signal. This device is suitable for applications such as hands-free communication in cellular phones or conference system phones.
