Complete ATSC (VSB)/NTSC channel
decoding solution with just two ICs
This chipset combines Philips long experience in analog TV with our
innovative approach to DTV, creating an outstanding system solution
showcasing Philips mixed signal technology expertise and offering very
high levels of integration, performance and flexibility. Designed for
analog and digital TV systems in North America and other ATSC
countries, the chipset enables manufacturers to design systems offering
end-users significantly improved reception at an attractive price.
The two key chips featured are the TDA8980 TV input processor and
the TDA8961 8-VSB demodulator/decoder for the ATSC DTV
standard. Designed specifically to reduce the chip count of first
generation front-ends, the TDA8980 eliminates many components by
integrating NTSC decoding, an IF circuit, picture and sound
demodulation and VSB downconversion, all into a single device.
This chipset gives true design flexibility, with the TDA8980 offering
both analog and digital capability, with comprehensive analog source
selection and also providing format conversion. This ensures glueless
support for the many legacy inputs a digital hybrid receiver is likely to
require.
Benefiting from real-world experience of VSB reception, Philips second
generation VSB demodulator handles the many problems caused by
man-made and naturally occurring echoes. Intelligent techniques in the
decoder allow it to cope with the delays and reflections caused by indoor
environments full of objects and moving people. Its maximum equalizer
length of 80
μ
s in conjunction with external software allows the receiver
to cope with very long static echoes. Patented NTSC co-channel
interference technology prevents strong NTSC signals from interfering
with their less powerful DTV counterparts on the same channel, without
the noise penalty associated with regular comb filter schemes.
As the roll out of digital TV accelerates, DTV receiver
manufacturers are looking for improved performance, flexibility
and cost reductions to meet the demands of the consumer
market. Philips’ latest reference design meets these stringent
requirements, using two new ICs, the second generation
TDA8961 VSB demodulator and the TDA8980 integrated
ATSC/NTSC TV input processor
