STV0900 Multistandard advanced dual demodulator for Satellite Digital TV and Data services set-top boxes Data Brief


The STV0900 features a high speed DVB-S2 Forward Error Corrector (FEC) which is designed to handle up to 180 Mega Channel bits per second at its input. To feed the FEC the STV0900 implements two identical demodulators, each capable of handling QPSK legacy, DVBS2 constant coding and modulation for satellite broadcast and Advanced Coding and Modulation for interactive services. The STV0900 supports mode switching on a frame basis without synchronization or data loss.


■ ■ Demodulation – RF interfaces – Each demodultor can handle: – – – – DIRECTVTM and DVBS QPSK DVBS2 QPSK, 8PSK and 16APSK Digital Nyquist root filter ■ Interfaces – Dedicated 27 MHz clock generation for back-end decoder – I2C serial bus interface – JTAG interface – boundary scan – 2 DiSEqCTM 2.x interfaces – GPIOs and interrupt lines – Monitoring through I2C serial interface Technology – 90 nm CMOS process – Multi supply: 1.0 V core, 2.5 V analog, 3.3 V digital interfaces – Power saving features Package – Exposed PAD LQFP 128 14×14, 0.4 pitch – 4 layer PCB recommended. With 0.20, 0.25, 0.35 excess bandwidth factors. – DVBS or DIRECTVTM – DVBS2 broadcasting (CCM) – DVBS2 adaptative (ACM) ■ Dual decoding – Up to 180 Mega DVBS2 channel bits per second (Mcbps) at input to FEC – Up to 130 Mcbps DVBS or DIRECTVTM legacy per FEC – Legacy DVB-S – DVB-S2 Transport stream management – – – Dual data to MPEG decoder Single ACM data to microprocessor DVB-S2 framing ■ ■ December 2006 Rev 1 1/5 5 For further information contact your local STMicroelectronics sales office.
