ATSC NTIA Converter System-on-Chip

The BCM3543 is a highly integrated low-power solution combining the functionality of a complete ATSC-to-NTSC converter on a single chip. It provides superior Advanced Televisions Systems Committee (ATSC) signal reception and demodulation under both static and dynamic multipath conditions, with functionality targeted at National Telecommunications and Information Administration (NTIA) coupon-eligible converter box programs for analog switch off.

The BCM3543 is compatible with an ATSC antenna design available exclusively from Broadcom. The BCM3543 exclusive antenna provides a high-performance indoor solution that only requires a single cable interface, eliminating difficult and costly outdoor installations. The antenna control is seamlessly integrated into the BCM3543 user interface, eliminating the need for consumers to manually adjust the antenna position in order to receive optimal signal reception.
