OVERVIEW
The BCM3341 offers the industry a highly integrated, cost effective approach to developing voice cable modem solutions for the delivery of primary or secondary line telephony. The BCM3341 provides a seamless interface to the BCM3349 single chip DOCSIS/EuroDOCSIS™ 2.0 cable modem.
In conjunction with the CablexChange software suite, the BCM3341 enables a leading performance, full featured voice cable modem solution that supports a wide range of protocols, vocoders, and other software features to be implemented in a single firmware image, reducing software complexity and flash storage requirements.
Integrated battery supply sensing, SRAM, system reference clock inputs, and codecs simplify design and significantly reduce system bill of materials for lower total system cost and improved time to market.
