Wideband RF synthesiser/PLL operates on low power

Integrated Device Technology introduces the 8V97051, a wideband RF synthesiser/PLL (phase lock loop) that operates on low power and delivers low-phase-noise performance. It claims fewer and lower power spurs than competing products available in the market.

The 8V97051 contains an integrated voltage-controlled oscillator (VCO) with a large tuning range capable of providing multi-band 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 comes in a compact 5mm x 5mm 32-VFQFN package and is pin compatible to similar devices from other manufacturers.

The 8V97051 has a figure of merit of -231dBc/Hz, which enables superior phase noise performance. In addition to offering low phase noise, the 8V97051 provides 16bits of frequency resolution that suits it for precise RF instrumentation or radar applications. This device can also be used in microwave transceivers and industrial electronic products.

The 8V97051 can generate frequencies from 34.375MHz to 4.4GHz and consumes 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.
