Broadcom Delivers Multi-Channel DVB-S2X Satellite Set-Top Box Chip

  • Adds Support for Next- Generation Satellite Extensions with Full Band Capture and Eight Demodulators in a Single Chip

COLOGNE, Germany — ANGA COM — Broadcom Corporation (NASDAQ: BRCM), a global innovation leader in semiconductor solutions for wired and wireless communications, today announced a satellite set-top box (STB) solution that delivers a boost in performance, lower power and support for the new DVB-S2X broadcast standard(1). The new BCM45308 system-on-a-chip (SoC) device integrates Full Band Capture (FBC) technology to provide satellite operators with more efficient video and IP service distribution to subscribers’ connected devices throughout the home.

The Broadcom BCM453xx Series dramatically simplifies system design and cost by integrating dual FBC Analog Digital Converters (ADCs) and up to eight demodulators in a single chip. The inclusion of FBC technology and DVB-S2X demodulators allows operators to digitize the entire 250-2350 MHz spectrum and provide flexible bandwidth deployment and tuning function in the digital domain, which enables a drastic reduction of tuner area and power. Remote diagnostics capabilities provided by FBC technology saves operators costly on-site customer visits and pairs with FastRTV® technology to provide quick channel change regardless of frequency.

“The benefits of Full Band Capture paired with the newest broadcast standard for satellite television continue Broadcom’s efforts to provide operators with the most advanced products to benefit consumers,” said Nicholas Dunn, Broadcom Vice President of Direct Broadcast Satellite Marketing. “With the push to offer Ultra HD/4K programming, the added benefits of the S2X extensions, especially with channel bonding, will enable operators to better utilize their available bandwidth to deliver these additional services to their subscribers.”

The latest DVB-S2X satellite standard offers improved operating range and performance in direct-to-home (DTH) satellite markets to cover additional subscriber deployments and business applications. The BCM453xx Series supports all new DVB-S2X coding rates, modulation schemes, channel bonding and sharper roll off factors to improve efficiency on transponder bandwidth.

The BCM453xx Series of devices are ball compatible to Broadcom’s BCM452xx DVB-S2 Series of devices to provide a very quick and easy upgrade path to support the S2X standard.
