Integrated Device Technology has introduced a wideband RF synthesiser/PLL (phase lock loop) with low power consumption and excellent phase noise performance. The 8V97051 also generates fewer and lower power spurs than similar competing devices. This combination of characteristics offers a competitive advantage for achieving optimal RF transmission and reception.
In addition, the 8V97051 offers an integrated voltage-controlled oscillator (VCO) with a large tuning range capable of providing multiband local oscillator (LO) frequency synthesis, limiting the need for multiple narrow-band RF synthesisers/PLLs. This reduces the bill of materials and design complexity, lowering the cost of developing radio frequency products. The 8V97051 is offered in a compact 5x5mm 32-VFQFN package and is pin compatible to similar devices from other manufacturers.
The device’s low-power consumption is ideal for high-performance applications with limited or no air flow, such as RF cards in base stations.
The 8V97051 has a figure of merit of -231 dBc/Hz, which enables superior phase noise performance. In addition to offering low phase noise, the 8V97051 provides 16 bits of frequency resolution that makes it ideal for precise RF instrumentation or radar applications. This device can also be used in microwave transceivers and industrial electronic products.
“IDT now offers a device that is both wideband and delivers excellent phase noise performance without compromising low power consumption,” said Louise Gaulin, vice president and general manager of IDT’s Network Communications Division. “The 8V97051 provides a solution that addresses the challenges of frequency generation for high-performance mixers and demodulators in RF board designs.”
The 8V97051 can generate frequencies from 34.375 MHz to 4.4 GHz and consumes only 380mW. The device delivers phase noise performance of -143dBc/Hz at 1MHz offset for a 1.1GHz output, and -146.5dBc/Hz at 1MHz offset for a 700MHz output.
