Universal digital cable demodulator
Description
The STV0297J is a highly integrated device, compliant with DVB-C/ITUJ83-A/B/C. It provides a small footprint, low-power solution enabling it to be easily integrated into broadcast and interactive set-top boxes and network inteface modules. Furthermore, the STV0297J is the first QAM demodulator with the integrated support for transport stream multiplex frame required for Japanese cable set-top boxes. Application: Advanced solution for very low-cost broadcast and interactive cable set-top boxes ADC Trellis decoder De-randomiser De-interleaver RS FEC decoder MPEG sync TSMF function Output formatter Bit error rate tester Shared RAM WBAGC delayed AGC I²C interface Symbol timing recovery Carrier recovery Clock generation Lock status IRQ generator Quadrature demodulation Nyquist filteringAGC Derotator Channel equaliser FEC B FEC A/C Signal quality estimator I²C repeater CLK to all registers AGC1 AGC2 SCL SDA SCLT SDAT XTAL Output stream Vin + Vin - DEMODULATOR FEC ADC Trellis decoder De-randomiser De-interleaver RS FEC decoder MPEG sync TSMF function Output formatter Bit error rate tester Shared RAM WBAGC delayed AGC I²C interface Symbol timing recovery Carrier recovery Clock generation Lock status IRQ generator Quadrature demodulation Nyquist filteringAGC Derotator Channel equaliser FEC B FEC A/C Signal quality estimator I²C repeater CLK to all registers AGC1 AGC2 SCL SDA SCLT SDAT XTAL Output stream Vin + Vin - DEMODULATOR FEC
