RF Synthesizers & PLLs


IDT offers very low phase noise, low-spurious RF synthesizers / PLLs that address the challenges of frequency generation for high performance mixers, modulators and demodulators in RF board designs. The RF Synthesizers / PLLs are also used to directly provide a clock reference to high speed RF Converters.

The 8V9705x wideband RF synthesizers / PLLs with integrated VCO offer an industry-leading combination of high performance, low power consumption and wide tuning range.

The 8V9705x RF synthesizers feature 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 synthesizers / PLLs. This reduces the bill of materials, and the design complexity, lowering the cost of developing radio frequency products. They provide solutions that address the challenges of frequency generation for high performance mixers and demodulators in RF board designs.

The RF synthesizer's low power consumption is ideal for high-performance applications with limited or no air flow, such as RF cards in base stations, or for applications powered over Ethernet and portable instrumentation.

In addition to offering low phase noise, the 8V97051 and 8V97053 (and the 8V97053L) RF synthesizers / PLLs provide 16 bits of frequency resolution that makes them ideal for precise RF instrumentation or radar applications. These devices can also be used in microwave applications and industrial electronic products. Extended registers allow for additional resolution and features for further control of the LO function.
