Broadcom Powers D-Smart’s Digital Channel Stacking Solution (DCSS)

  • Enables Leading Operator in Turkey to Expand Subscriber Services Offered within Multiple Dwelling Units

IRVINE, Calif. — Broadcom Corporation (NASDAQ: BRCM), a global innovation leader in semiconductor solutions for wired and wireless communications, today announced that D-Smart, a leading digital broadcast operator in Turkey has started volume production of the next-generation Digital Channel Stacker based on Broadcom’s low-power satellite Out Door Unit (ODU) chip. The BCM4554 addresses consumer demand for satellite services by minimizing deployment costs allowing operators to provide consumers with additional service offerings.

Operators face many challenges when implementing new set-top boxes (STBs) with multiple tuners, additional room installations and multi-dwelling installations. Broadcom’s BCM4554 adds support for up to 32 resident STBs on a single coaxial cable within a multiple dwelling unit, enabling operators to deliver additional services to more subscribers without requiring new satellite dish installations. These offerings also enable operators such as D-Smart to improve services such as faster channel changing by assigning more channels to a single STB.

“Our collaboration with Broadcom has allowed us to develop our next generation DCSS with differentiated features that add real value to satellite operators” said Erdogan Simsek, D-Smart CTO. “Broadcom’s ability to develop technologies and products that address satellite operator challenges in a timely and cost effective fashion was key in D-Smart’s decision to choose Broadcom.”

D-Smart’s new generation Digital Channel Stacker employs 64 adjustable filters, accepts input from a standard Quatrro LNB and has the ability to reconfigure all input and output parameters dynamically over the air. The new design can be installed seamlessly to an existing multi-switch environment and can stack channels from 250MHz to 2350MHz. STBs based on Broadcom’s BCM7362 and BCM45204+ BCM7250 have been developed with wideband and full-band capture (FBC) features to work with this Digital Channel Stacker solution.

“D-Smart has embraced the whole home architecture based on Broadcom products and has designed a feature-rich Digital Channel Stacker product,” said Nicholas Dunn, Broadcom Vice President of Marketing, Broadband & Connectivity Group. “The BCM4554 enables operators to streamline the cabling, hardware and installation costs associated with supporting multiple set-top boxes and ultimately simplify satellite distribution to their customers.”

Broadcom’s BCM4554 offers a higher level of integration while consuming less power than previous generation chipsets. It also enables direct sampling of low-noise block (LNB) outputs across worldwide ODU satellite markets. The simplified design of Broadcom’s new ODU chipset allows 32 DVB-S2 channels to be stacked on a single coaxial cable to service any STB in a home, simplifying and reducing satellite operator installation costs.

BCM4554 Key Features:

  • Second generation with reduced power and better integration in 28nm process
  • 4 RF inputs and 1 RF output covering the 250 to 2350 MHz frequency range
  • 32 user-band output channels
  • 32 output channels selectable from any LNB input
  • Frequency shift keying (FSK) and digital satellite equipment control (DiSEqC)


Broadcom’s BCM4554, BCM7362, BCM45204 and BCM7250 are all in production.
