Broadcom rolls out new low-power cable multi-channel receivers

Broadcom Limited, maker of analogue and digital semiconductor connectivity solutions has unveiled a new family of 28 nm (nm) low power cable multi-channel receiver system-on-chip (SoC) solutions. The BCM3158x family integrates Full-Band Capture (FBC) technology with 4, 8 or 16 QAM demodulators, providing pin compatible front ends for a broad range of hybrid cable/IP set-top box (STB) and home gateway platforms.

Delivering up to 1.2 GHz operation, Broadcom's third-generation FBC devices provide frequency agility for video services in hybrid QAM/DOCSIS? 3.1 networks. This allows operators to have complete spectrum flexibility to provide consumers with High Definition (HD) and Ultra HD video service.

Broadcom's industry low-power Full-Band Capture technology enables the lowest power per demodulated channel with a 75mW/channel power consumption. Broadcom's wake-on transport technology allows the main SOC to be placed into deep sleep mode while the BCM3158x monitors the frequency band on the cable input for operator messages. This allows the STB to remain in deep sleep mode while allowing for wake-up on demand by the operator for DVR recording, guide or software updates.

The real time radio frequency (RF) spectrum analysis and diagnostic capabilities of the BCM3158X Family enable operators to remotely monitor and optimise their cable plants. The devices add analysis functions and send diagnostic data to customer service portals via protocols such as TR-69, SNMP or HTML. This allows cable operators to remotely and non-intrusively monitor each device in their network and proactively address network issues, reducing truck rolls and support costs.

Broadcom's BCM3158x Family including the BCM31584, BCM31588 and BCM31586 are now sampling.
