MaxLinear Inc. (NYSE: MXL),
a leading provider of integrated radio frequency (RF) and mixed-signal integrated circuits
for broadband communications applications, today announced the MxL582, an eight-channel Full-Spectrum Capture™ (FSC™) tuner-demodulator supporting Extended L-Band (XL-Band) for DVB-S/S2 satellite home media gateways and set-top boxes (STB).
Traditionally, the entire 4.1GHz satellite spectrum available at the satellite dish antenna or outdoor unit (ODU) has been delivered to the home utilizing four coaxial cables, which connect the low-noise block downconverter (LNB) in the ODU to the set-top-box receiver inside the home. Each coaxial cable only carried approximately 1 GHz of spectrum in the L-band (950 MHz to 2150 MHz) constrained by the satellite set-top-box receiver’s ability to receive RF signals in the L-band only.
MaxLinear’s MxL582 is a dual-input RF receiver capable of receiving 2 GHz of Extended L-band spectrum (300 MHz to 2350 MHz) at each RF input. By extending the capture bandwidth of each of the receiver’s RF inputs to 2.05 GHz, MaxLinear’s XL-Band technology allows satellite operators to deliver 4.1GHz of spectrum from a low-cost wideband LNB to a MxL582-based gateway or set-top receiver utilizing only two cables.
As a result, operators are able to realize a significant reduction in the overall system cost and power consumption associated with the rollout of next generation multi-channel gateway boxes and services.
The eight-channel MxL582 Full-Spectrum Capture receiver provides the highest level of integration with eight integrated DVB-S/S2 demodulators, on-chip LNAs and RF-splitter, and configurable transport stream multiplexing capability over parallel or serial interfaces.
The eight demodulators are capable of tuning or receiving channels over the entire 4.1GHz of spectrum present at the dual RF inputs of the chip. Further, the MxL582’s integrated RF splitter enables STB makers to develop scalable platforms supporting up to 16 channels by pairing two MxL582 devices via the splitter, without utilizing any additional expensive external active components.
