Demodulator uses 90nm tech to offer upgrades for STBs

STMicroelectronics (ST) announced the STB0899 DVB-S2 demodulator that supports both the latest DVB-S2 specification (which provides increased capacity to enable more channels and HDTV capability in next generation satellite services) and the original DVB-S standard used over the last ten years by satellite operators worldwide.

The dual standard capability means that STB manufacturers can incorporate the STB0899 now in 'DVB-S2-ready' STBs, to provide a seamless upgrade path for consumers as services become available.

The STB0899 is built using 90nm process technology, providing lower cost through a smaller sized die, and reduced power consumption; additional software-based power management features are built in. It supports normal QPSK (quadrature-phase-shift-keying) and 8PSK modulation, as well as the DVB-S2 pilot processing that enables more robust reception.

Support is provided for the DiSEqC 2.0 (Digital Satellite Equipment Control) specification, a widely used protocol that allows a satellite STB to control peripheral devices connected to the coaxial cable.

The STB0899 is priced at $12 when purchased in large volumes, packaged in a 100-pin exposed pad quad flat pack (QFP), and is available in sample quantities, with volume production planned for Q1 2005.
