SKY73134 synthesizer

Skyworks Solutions Inc. has launched high-performance broadband synthesizers spanning ultrawide frequency ranges from 375 MHz to 5.6GHz. Designed to cover all GSM, W-CDMA and LTE frequency bands with one device, supports the 3G and 4G base station providers including Ericsson, Huawei, ZTE, Alcatel/Lucent, and Nokia/Siemens.

The SKY73134's performance allows radio designers to support increasing levels of voice and data traffic volumes, enables design flexibility across multiple applications. The device is also applicable for use in microwave-link and software-defined radios.

The SKY73134 is a wideband integer-N frequency synthesizer with an approximate 6GHz locking range. This extremely small 5mm x 5mm device includes four differential voice-controlled oscillators which, by applying internal VCO frequency division, continuously cover the output frequency from 0.375GHz to 5.6GHz.

The integrated phase noise from 100Hz to 100kHz measures less than 0.6 RMS at 960MHz frequency. In addition, the phase noises at 100kHz, 1MHz and 3MHz frequency offsets are -115dBc/Hz, -143dBc/Hz and 150dBc/Hz respectively, making the SKY73134 a suitable solution for GSM/Edge, CDMA/W-CDMA 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.

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 neededrequiring 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 solutionssignificantly reducing board size requirements, cost, and streamlining customer supply logistics."

Volume production of the SKY73134 is scheduled to begin in April 2010.
