BCM3545

Quadrature Amplitude Modulation (QAM) Digital Receiver

Currently Viewing:

The Broadcom BCM3545 is a highly integrated low-power solution combining the functionality of a complete QAM-to-NTSC converter on a single chip.
 
The BCM3545 provides SCTE-40 QAM signal reception, with functionality targeted at DTA specification or similar converter boxes for analog cable switch-off. This all-silicon solution minimizes part count and provides ease of manufacturing. The comprehensive integration of Analog-to-digital Converters (ADCs) and Digital-to-analog Converters (DACs) simplifies system design and cost and has direct interfaces to all other system components, including serial Flash (SPI), tuner (I2C), push buttons and an infrared demodulator.
