Sony Corp. has announced the availability of the BTD-UB451 television tuner module that demodulates both analog and digital television broadcast signals.

Designed to support the standards used in the United States and South Korea, the module can demodulate NTSC-M signals for terrestrial and analog broadcast, VSB signals for digital terrestrial broadcast, and QAM signals for digital CATV.

The BTD-UB451 has an RF block that selects and amplifies specific channel signals among the television signals received from an antenna. A demodulator then converts the selected signal and amplifies it into a baseband signal.

The modulator integrates a DSP and demodulation software to accommodate the various modulations formats for both analog and digital broadcast.

The 123.8-by-43.5-by-14mm module has a video SNR >48dB (NTSC-M) and a minimum input sensitivity of <-80dBm (VBS). It has a receiving band between 57MHz to 890MHz and consumes a maximum of 4W. It is rated for operation from 00C to 450C.

The BTD-UB451 is priced at about $272.33.
