MaxLinear Inc. (NYSE: MXL),
a leading provider of integrated radio frequency (RF) and mixed-signal integrated circuits
for broadband communications applications, today announced the MxL86x family of 24-channel, Full-Spectrum Capture™ (FSC™) band translation and channel stacking system on chip (SoC) devices that are the industry’s lowest-power single-chip solutions for next-generation satellite digital outdoor units (ODUs).
With a very high level of integration and the industry’s lowest power consumption, the MxL86x chips are designed for worldwide satellite operators that are transitioning to high-density, channel-stacking ODUs. The devices are also suitable for multi-dwelling unit switches.
The availability of next-generation digital ODUs is essential to satellite operators being able to deploy media gateway server set-top-boxes inside the home that can simultaneously deliver multiple channels to multiple IP-client devices such as television screens, IPTV set-tops, smartphones, tablets and others.
Existing analog channel-stacking ODUs are based on complex multi-chip solutions that require expensive external discrete RF filters, a separate microcontroller, and additional FSK or DISEqC ICs for communication between the set-top box (STB) and the ODU. Those solutions do not scale beyond 12 channels stacked in L-Band due to RF filtering architecture limitations.
Leveraging MaxLinear’s ultra-low power Full-Spectrum Capture technology, the MxL86x single-chip devices integrate a complete 24-channel digital stacking switch platform, including filters, communication modems and a microcontroller, which dramatically reduces the ODU system costs and addresses significant legacy thermal design challenges.
MaxLinear’s ultra-low power FSC technology is ideally suited to meet the stringent low power constraints imposed by cost and safety requirements of delivering power from the home set-top-box to the outdoor unit, on the very same coaxial cable that brings the signals into the home.
This 24-channel implementation simplifies the cabling infrastructure to the home and meets the increasing demand for multi-channel content distribution, enabling multi-screen, fast-channel change and PVR applications.
