Philips Semiconductors
ATSC 8-VSB demodulator and decoder
Preliminary specification
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 µm 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 µs
Adaptation based on ATSC field sync (trained) and/or
8-VSB data (blind)
Trellis (Viterbi) decoder
Rate 23 (Rate 12 Ungerboeck code based).
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).
