GENERAL DESCRIPTION
The TDA8960 is an ATSC-compliant demodulator and forward error correction decoder for reception of 8-VSB
modulated signals for terrestrial and cable applications:

• Terrestrial:reception of 8-VSB modulated signals via standard 6 MHz VHF/UHF terrestrial TV channels
(TV channels 2 to 69 in the United States)
• Cable:reception of 8-VSB modulated signals via standard 6 MHz VHF/UHF cable TV channels.

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
• 0.4µm 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 +10.5µs
• 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).

APPLICATIONS
