COMPLETE REFERENCE DESIGN FOR
HYBRID ATSC/NTSC RECEIVER FRONT-ENDS
This reference design demonstrates a complete solution for building hybrid ATSC/NTSC receiver front-ends for
HDTV sets, STBs and PC/multimedia applications, using just two highly integrated, second generation ICs.
TDA8980HL ATSC/NTSC TV
INPUT PROCESSOR
Key features
• NTSC-M colour decoder tuned with a
12 MHz reference crystal
(or external clock signal)
• VSB IF circuit for pre-processing
DTV signals
• Alignment-free PLL demodulator Vision
IF circuit without external components
• Sound IF amplifier with separate input
for single reference QSS mode and
separate AGC circuit
• Alignment-free FM sound demodulator
generates the input signal for a BTSC
stereo decoder
• Video source selection with 2 external
CVBS or Y/C inputs and an
independently switchable output
• Two 10-bit video ADCs for converting
selected YUV signals (video mode)
or downconverted I&Q signals
(VSB mode)
• Two 16-bit audio A/D converters and
I2S formatter
• Up to four stereo analog inputs and
one I2S input
• ITU656 or VSB formatter
• Direct input to video ADCs
Integrating many components into a single
chip, the TDA8980HL is designed for both
TV and multimedia applications. Containing
an NTSC-M colour decoder, an IF circuit
and ADCs for audio and video, it can also
generate a ‘mixed down’ I signal for
demodulation of a digital broadcast VSB
input. An I2C-bus controlled internal switch
enables the device to switch between analog
NTSC and digital 8-VSB IF signals.
When decoding NTSC, the chip digitizes the audio signals into an
I2S stream using on-chip audio stereo 16-bit ADCs, and the video
information into an ITU656 stream via the on-chip video ADCs.
An incoming 6 MHz wide 8-VSB IF signal is downconverted to a low
IF, centred at 4 MHz, which is digitized using an on-chip 10-bit ADC
and gluelessly interfaced to the VSB demodulator for further
processing. In a typical application, the TDA8980 handles AGC,
eliminating the need for external components such as an op-amp loop
integrator.
It has an internal 2-D adaptive comb filter for NTSC, and a YUV
interface allows simple connection of additional picture enhancement
ICs such as a 3-D comb filter. For sound decoding, external
devices - a BTSC sounder decoder, for example - can be connected.
TDA8961 DTV DEMODULATOR/DECODER
General features
• One-chip ATSC-compliant demodulator and concatenated
Trellis (Viterbi)/Reed-Solomon decoder with de-interleaver
and de-randomizer
• Parallel (8-bit) or serial MPEG2 transport stream output
• On-board I2C-bus interface
• MPEG2 serial transport stream input
