STV0297J Datasheet | STMicroelectronics

Description The STV0297J is a highly integrated device, pliant 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 DEMODULATOR Quadrature demodulation Vin + Vin ADC Nyquist filtering AGC Derotator Channel equaliser Signal quality estimator AGC1 AGC2 WBAGC & delayed AGC Symbol timing recovery Carrier recovery FEC B FEC A/C Lock status & IRQ generator SCL SDA I²C interface to all registers Trellis decoder De-randomiser De-interleaver RS FEC decoder MPEG sync Shared RAM TSMF function I²C repeater CLK Output formatter Output stream Bit error rate tester Clock generation SCLT SDAT XTAL March 2004 1/2 Features - Integrated high performance ADC - Support for 4-, 16-, 32-, 64-, 128-, 256-point constellation variable symbol - Rate from 0.87 MBaud to 11.7 MBaud - Robust integrated adaptative equaliser - I²C serial bus and I²C repeater - DVB mon parallel interface-pliant serial and parallel data output - Lock time <100ms - Low power consumption <0.5W typ. - TQFP 64 10x10 package Ordering information Device number STV0297J STV0297JT STV0297J-TMM Description QAM FEC A/B/C QAM FEC A/B/C with tape and reel Development platform Information furnished is believed to be accurate and reliable.
