SMC Networks will be using MaxLinear’s digital receivers for a line of DOCSIS 3.0 cable modems and gateways.

SMC is incorporating the MxL265 Full-Spectrum Capture (FSC TM ) digital cable front-end receiver in a new 16x4 cable gateway family, the chip vendor said. SMC had been using MaxLinear receivers in previous models.

SMC’s new family of DOCSIS-based CPE includes the Veloxite D3G1604W, which recently achieved certification from Cable Labs.

The D3G1604W is a high-speed wireless data gateway designed using the MxL265 cable tuner capable of receiving up to 680 Mbps via 16 bonded downstream channels.

The D3G1604W also features flexible Wi-Fi configurations, from Dual Band Dual Concurrent 3x3 Wi-Fi, to Single Band 2.4GHz 3x3 or 2x2, as well as the latest in 802.11ac technology.

“SMC engineered Veloxite using the industry’s best-in-class solutions to achieve outstanding product performance,” said SMC’s EVP & COO Joe Wytanis. “The collaboration with MaxLinear extends from the Veloxite 8x4 wireless gateways to the 16x4 and 24x8 product lines.”

Based on MaxLinear’s low-power 40nm CMOS process technology, the MxL265 offers a monolithic digital cable front-end with integrated low-noise amplifier (LNA) and signal conditioning functions combined with a Full-Spectrum Capture receiver.

In full 16-channel receive mode of operation, the MxL265 provides up to 800Mbps downstream speeds and consumes less than 110 mW per channel, eliminating the need for expensive heat removal components such as fans, heat shields and heat sinks inside customer equipment, MaxLinear claimed.  

Additionally, the MxL265 supports remote spectrum analyzer functions that report network health and performance parameters, which can be used by cable operators in managing and troubleshooting their networks. This innovative feature allows cable operators utilizing SMC’s new Veloxite gateways to avoid costly technician visits to customer homes by remotely monitoring and diagnosing potential problems with customer premises equipment.

The MxL265 16-channel DOCSIS 3.0 digital cable receiver is available now in a standard 7mm X 7mm QFN package.
