Micronas has released a dual-tuner DVB-S2 PCI Express card reference design for home theater solutions. Each channel of the MicSidewinder 2D-X supports the new DVB-S2 standard enabling full HDTV quality, as well as the legacy DVB-S standard for SDTV. Equipped with two symmetric receiver channels the design enables PiP and PVR applications.

The MicSidewinder 2D-X reference design is based on the company's nGene APB 7202A PCI Express controller, combined with the STB0899/STB6100 DVB-S2 chipset from STMicroelectronics. The STB6100 silicon tuner, which also receives conventional DVB-S signals, is optimized to handle DVB-S2 higher-order modulations with minimum phase noise. The STB0899 converts DVB-S2 signals into the digital video transport stream data with an outstanding level of performance. Both devices are optimized for cost-effective consumer applications.

In combination with H.264 (MPEG-4 AVC), the new DVB-S2 standard provides a significant increase in the number of standard definition or HDTV channels that can be broadcasted by each satellite.

Micronas' nGene dual-channel multimedia PCI Express controller delivers the bandwidth needed for two HDTV channels, eliminating potential bottlenecks that may occur with conventional PCI connectivity. nGene is certified by the PCI-SIG, the industry standard body for PCI Express technology, to be PCI Express 1.0a compliant. This certification guarantees that MicSidewinder 2D-X is compatible with a wide variety of PC motherboards offering PCI Express x1 slots.

Micronas' new reference design supports Free TV services and relies on USB-attached conditional access solutions or Soft-CAM solutions for Pay TV reception.
