Wideband RF synthesiser/PLL runs at low power levels

May 22, 2015 // By Graham Prophet
IDT’s (Integrated Device Technology) 8V97051 is a wideband RF synthesiser/PLL (phase lock loop) with low power consumption and low-phase-noise performance. The device also claims fewer and lower power spurs than similar competing devices.

8V97051 contains 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 comes in a compact 5 x 5 mm 32-VFQFN package and is pin compatible to similar devices from other manufacturers.

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 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 34.375 MHz to 4.4 GHz and consumes 380 mW. The device delivers phase noise performance of -143 dBc/Hz at 1 MHz offset for a 1.1 GHz output, and -146.5 dBc/Hz at 1 MHz offset for a 700 MHz output.
