Product Overview
The Intel CE 9500 PC-TV USB “stick” reference design is a complete DVB-T digital terrestrial TV receiver solution for the PC. The two-chip solution is based on the Intel CE 6230 DVB-T demodulator with USB 2.0 interface and the MaxLinear* MxL500x terrestrial tuner. The design addresses the needs of USB-based DVB-T PC-TV receivers.
This PC-TV USB “stick” reference design is a production-ready solution that enables fast time-to-market. Intel directly supports hardware and software design with a comprehensive suite of documentation and test results. This PC-TV receiver solution offers high performance signal handling with low power consumption and specifi -cally addresses the system and fi eld challenges of PC USB-based TV receivers.
Intel CE 9500 PC-TV USB Reference Design Received digital terrestrial signals are down-converted to a low IF by the MaxLinear tuner and then passed to the CE 6230 DVB-T demodulator, which integrates Intel’s DVB-T demodulator with an Intel 8051 microcontroller. Audio and Video Transport Stream output is carried via the USB 2.0 interface to the PC host.
