Skyworks Launches Industry's Widest Frequency Range Integrated Synthesizers for 3G/4G Base Stations
broadband synthesizers spanning ultra wide frequency ranges from 375 MHz to 5.6 GHz. Skyworks' new device, which is designed to cover all GSM, WCDMA and LTE frequency bands with one device, supports the world's leading 3G and 4G base station providers including Ericsson, Huawei, ZTE, Alcatel/Lucent, and Nokia/Siemens. Leveraging state-of-the-art design techniques, Skyworks has been able to deliver very stringent requirements all on a single silicon die.
The SKY73134's performance allows radio designers to support increasing levels of voice and data traffic volumes, enables design flexibility across multiple applications, and is applicable for use in
microwave-link and software-defined radios. With the addition of this new synthesizer, Skyworks continues to broaden its infrastructure and linear products portfolio. At a higher level, the company is
capitalizing on mobile Internet applications - supporting both handsets as well as infrastructure networks.
According to Cisco, mobile data traffic volumes are projected to increase at a compounded annual growth rate of 131 percent from 2008 to 2013. As a result, mobile operators will need to begin to install new base stations, routers and backhaul network equipment starting now to avoid network traffic jams and to preserve their highly profitable data service revenue. Furthermore, upgrades and expansion to existing infrastructure will be needed - requiring increased analog and mixed signal content. The SKY73134 addresses these needs and does so with one common device for all platforms.
"Skyworks is pleased to be expanding its product portfolio with a solution offering the broadest frequency range available on the market today," said Wesley Boyd, director of marketing at Skyworks. "This breakthrough synthesizer enables customers to implement a one-chip solution for all frequencies versus more than ten different discrete solutions - significantly reducing board size requirements, cost, and streamlining customer supply logistics."
About the SKY73134
The SKY73134
is a wideband integer-N frequency synthesizer with an approximate 6 GHz locking range. This extremely small 5 x 5 millimeter (mm) device includes four differential VCOs which, by applying internal VCO
frequency division, continuously cover the output frequency from 0.375 to 5.6 GHz.
The integrated phase noise from 100 Hz to 100 kHz measures less than 0.6 degree RMS at 960 MHz frequency. In addition, the phase noises at 100 kHz, 1 MHz and 3 MHz frequency offsets are -115 dBc/Hz, -143 dBc/Hz and 150 dBc/Hz respectively, making the SKY73134 an ideal solution for GSM/EDGE, CDMA/WCDMA and LTE base station transceivers.
The SKY73134 is controlled by a bi-directional read/write serial to parallel interface which allows flexible device configurations that may be locked with an external VCO or external PLL, or be used as a divider chain only. Furthermore, the device is a key building block for any radio system design including backhaul, military and satellite applications that require a combination of high performance, low power and multi-purpose features.
