CARLSBAD, CA: MaxLinear, a provider of integrated radio frequency (RF) and mixed-signal integrated circuits for broadband communications applications launches new Four-Channel Full-Spectrum Capture (FSC) tuner-demodulator devices that offer lowest power consumption for rapid-growing segment of the DVB-S/S2 satellite pay TV market including ultra-high definition (UHD) personal video recorders (PVRs).

The new four-channel ICs consists of MxL541C, with a single L-band (950-2150MHz) RF input and the MxL542C, with dual wide-band (250-2350MHz) RF inputs. The MxL541C supports the satellite Unicable LNB standard EN 50494 (also known as SatCR) and digital channel-stacking standard, EN 50607, which enables up to 32 user bands to be stacked and distributed over a single coax cable.

“The market for multi-channel satellite set-top boxes, PVRs and media servers is growing faster than the overall pay TV market. Recent technology advances in video compression with H.265 high efficiency video coding (HEVC) and ‘4K’ UHD televisions are generating new demand for set-top boxes that incorporate these latest technologies,” says  Jeff Heynen, Research Director for Broadband Access and Pay TV at IHS.

The devices are optimized for next-generation satellite gateways and set-top boxes with support for multi-screen viewing, personal video recorder (PVR) functionality and fast channel change capability. Integrated high performance low-noise amplifiers (LNAs) ensure that system performance is optimized while minimizing the bill-of-materials (BOM) cost and total power consumption.

MxL541C and MxL542C devices use MaxLinear’s Full-Spectrum Capture technology to receive the full L-band or XL-band of satellite spectrum, respectively. As a result, MxL54xC devices can simultaneously receive up to four DVB-S/S2 channels located anywhere in the satellite spectrum. The MxL54xC devices are compatible with 4G/LTE, WiFi, and other wireless interference signals that are typically present in consumer home environments.
