ATSC/VSB DIGITAL CABLE READY DTV RECEIVER

Digital Cable Ready 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 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
