Peregrine adds PLL with low-phase-noise figure of merit and supporting 5GHz operation

At the 2013 IEEE MTT-S International Microwave Symposium (IMS) in Seattle, WA, USA (4-6 June), Peregrine Semiconductor Corp of San Diego, CA, USA, a fabless provider of radio-frequency integrated circuits (RFICs) based on silicon-on-sapphire (SOS), announced it has further expanded its high-frequency product line with the Integer-N PE33241 phase-locked loop (PLL).

The UltraCMOS technology-based PLL features a very low-phase-noise figure of merit (FOM) of -230dBc/Hz, which improves the signal-to-noise ratio, helping to reduce the overall system cost while improving  performance. The device supports operation at 5GHz with a 10/11 pre-scaler modulus, making it suitable for industrial transceivers, specialized transceivers, and clock generators requiring low phase noise. The PE33241 suits RF frequency generation; L-, S- and C-band synthesizers; and clock recovery in communication systems, mobile terminals, telemetry, radar, and portable radios.

“Peregrine has been manufacturing PLLs for more than 20 years, and we’re pleased to expand our flagship product line,” says Mark Schrepferman, director of the commercial and industrial product line with Peregrine’s High-Performance Solutions business unit.

The low-phase-noise FOM of -230dB/Hz in the PE33241 PLL reduces interference, improving the link quality of the communication system. The PLL features a selectable pre-scaler modulus of 5/6 or 10/11, which provides design flexibility and minimizes unwanted frequency spurs. The device supports operation at 5GHz with the 10/11 pre-scaler modulus, and 4GHz with the 5/6 pre-scaler modulus. An integrated phase detector and flexible serial or direct hard-wire interfaces provide additional design flexibility. The new PLL features low power consumption of only 80mA at 2.8V, which reduces thermal issues and extends battery life.

The PE33241 is available in a 7mm x 7mm 48-lead QFN package, as well as in die form. Samples can be ordered in late June, and volume-production quantities are expected to be available in late July.
