MaxLinear And Peregrine Semiconductor Team On Dual-RF-Input Digital TV Reference Design

Stocks in this article: MXL PSMI

MaxLinear Inc. (NYSE: MXL), a leading provider of integrated radio frequency (RF) and mixed-signal integrated circuits for broadband communications applications, announced today a collaboration with Peregrine Semiconductor Corp. (NASDAQ: PSMI), founder of RF SOI (silicon on insulator) and pioneer of advanced RF solutions, to produce a dual-RF-input digital TV (DTV) front-end reference design.

Television sets incorporating this dual-RF-input front end will support reception of both digital terrestrial TV and cable TV for seamless channel browsing.

The reference design pairs MaxLinear’s MxL600 family (MxL601 and MxL661) of software-programmable, low power, global hybrid-television tuners with Peregrine’s low-power PE42750 RF switch in a fully tested, end-to-end solution including complete schematics, bill of materials and the Gerber files required to quickly implement a high-performance DTV solution.

The new front-end design gives OEMs a way to respond to the ever-increasing demand for DTV. This demand is driven, in part, by countries like China, where the Ministry of Industry and Information Technology (MIIT) has mandated that all televisions 40 inches and larger must integrate digital terrestrial receivers as of Jan. 1, 2014. This digital-receiver mandate expands to every television after Jan. 1, 2015.

“We have worked closely with our customers to develop a reference design that will meet all of their needs – from using proven, high-performance devices to delivering a complete blueprint that eases design of digital-TV front ends,” said Brian Sprague, MaxLinear’s Vice President and General Manager, Broadband and Consumer Products. “Peregrine has been a key partner in this effort, providing RF switches that deliver the isolation required for reliable reception of both terrestrial and cable TV, now a necessity in China.”

Technical HighlightsPeregrine’s PE42750 is a 75-Ohm, single-pole, double-throw (SPDT) RF switch for broadband consumer applications. Manufactured on Peregrine’s UltraCMOS® technology, the HaRP™-enhanced device features high linearity (IIP3 of 47.5 dBm @ 2200 MHz) and high isolation performance (80 dB @ 220 MHz and 63 dB @ 1 GHz).

In compliance with the FCC 15.115 standard, these performance levels are maintained in the unpowered state to prevent reflected signals between the terrestrial antenna and cable feed. This high level of isolation ensures reliable performance in consumer TV applications. The PE42750 covers a broad frequency range from 5 MHz to 2200 MHz, delivers low insertion loss (0.7 dB @ 5 MHz and 1.0 dB @ 1 GHz) and high ESD rating of 2000 V HBM on all ports.
