ATSC/VSB DIGITAL CABLE READY DTV RECEIVER

Plug and Play DTV System Solution

- 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

- 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
