ATSC 8-VSB demodulator and decoder
TDA8960
FEATURES
General features
One-chip Advanced Television Systems Committee
(ATSC)-compliant demodulator and concatenated trellis
(Viterbi)/Reed Solomon decoder with de-interleaver and
de-randomizer
0.4 m process
3.3 V device
64-lead QFP64 package
Boundary scan test
Output format: 8-bit wide bus.
8-VSB demodulator
On-chip digital circuitry for tuner Automatic Gain Control
(AGC)
Square root raised cosine filter with 11.5% roll-off factor
Fully internal carrier recovery loop
Mostly internal clock recovery and AGC loops with
programmable loop filters
External indication of demodulator lock.
Adaptive equalizer
Feed forward including a Decision Feedback Equalizer
(DFE) structure
Range of 2.3 to +10.5 s
Adaptation based on ATSC field sync (trained) and/or
8-VSB data (blind)
Trellis (Viterbi) decoder
Rate 2
3 (Rate
1
2 Ungerboeck code based).
Reed Solomon decoder
(207, 187 and T = 10) Reed Solomon code
Internal convolutional de-interleaving (I = 52; using
internal memory)
External indication of uncorrectable error; transport error
indicator bit in Motion Picture Export Group (MPEG)
packet header is also set
Followed by de-randomizer based on ATSC standard.
I2C-bus interface
I2C-bus interface to initialize and monitor the
demodulator and Forward Error Correction (FEC)
decoder. Operation without I2C-bus control is possible
(default).
