Blue Danube Selects MaxLinear Clock Jitter Cleaner Product for Massive MIMO Wireless Systems

MaxLinear’s new PM7531 provides ultra-low jitter clock that enhances system performance for BeamCraft™ product

BARCELONA – Feb. 27, 2017 – MaxLinear Inc. (NYSE: MXL), a leading provider of radio frequency (RF) and mixed-signal integrated circuits for the connected home and wired and wireless infrastructure markets, today announced that Blue Danube has selected its PM7531 as the high-accuracy clock in BeamCraft™, its next-generation massive MIMO product.

Blue Danube’s BeamCraft™ products generate agile 3D beams for unparalleled accuracy in spectrum power placement to improve capacity for 4G/5G networks. BeamCraft systems can be easily mounted onto existing antenna locations on towers and buildings and support both AWS and PCS frequency bands. Recently, Blue Danube concluded commercial trials of the industry’s first FDD massive MIMO system.

The PM7531 is a low-power clock synthesizer with an integrated jitter attenuator that enables the industry’s lowest-phase noise of -165dBc/Hz @ 122.88MHz carrier frequency and 800kHz offset. Operating at less than 700mW, The PM7531 integrates high-performance phase-lock loops (PLLs) and voltage-controlled oscillator (VCO) to condition and regenerate precision system clocks up to 3.2GHz for ADCs, DACs, SerDes and FPGAs used inside radio modules.

PM7531 features including holdover, switchover, multiple inputs, digital delay, dividers and 18 programmable output format drivers. The device’s ultra-low jitter enhances the overall system performance for next-generation active antenna systems, 4G/5G macro cell base station, wired communications, test and measurement, medical imaging, software defined radio (SDR) and digital broadcast applications, while reducing overall bill of materials (BOM) cost.

“MaxLinear’s clock product family has been very well received by major telecom customers due to its high level of integration, unmatched phase noise performance, and lowest power consumption – all of which is required to enable high-speed serial links,” said Brendan Walsh, Vice President of Marketing, Wireless Infrastructure Group. “We’re pleased to enable the high-performance clock jitter cleaner for Blue Danube’s BeamCraft products.”

“MaxLinear’s PM7531 provides the ultra-low jitter clock, and proven performance we need to quickly integrate and commercialize our active antenna products with existing infrastructure solutions,” said Mihai Banu, CTO of Blue Danube Systems.”

The PM7531 is available for volume production. For more information email: info@maxlinear.com.
