ConnecTV™ Plug and Play DTV Receiver
FEATURES
SUMMARY OF BENEFITS
• Integrated VSB/QAM QAMLink® receiver
- 12-bit A/D converter with internal AGC amplifier
- Full equalizer architecture spans up to –35 to 49 µs delays
- Direct IF sampled architecture reduces system cost
- Single IF signal path for QAM/VSB/NTSC to reduce system
costs
- ITU-T J.83 Annex A/B/C FEC modes
- MPEG-2 transport output (serial/parallel)
- All-digital clock and carrier recovery
- Integrated PLLs to minimize external components
- All acquisition times typically less than 50 ms
• QPSK out-of-band receiver
- 100–200 MHz receiver LO with input AGC and 6-bit A/D
- Variable symbol rate QPSK receiver
- Digital demodulator, Nyquist filters, tracking loops, and
four-tap adaptive equalizer
- DVS-167 (Davic)/DVS-178 (DigiCipherII) FEC decoder
• NTSC/PAL IF Demodulator
- Adjacent channel rejection filters
- Programmable digital audio trap filter
- Programmable group delay compensation filter
- Analog Composite Video Baseband Signal (CVBS) output
- FM demod output supports internal BTSC stereo decoder,
external BTSC stereo decoder (baseband or IF input), or
external Zweiton M decoder
