Peregrine Semiconductor recently 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, improving the signal-to-noise ratio and reducing the overall system cost while improving performance.

The device supports operation at 5GHz with a 10/11 prescaler modulus, making it ideal for industrial transceivers, specialised transceivers, and clock generators requiring low phase noise. The PE33241 PLL is ideal for RF frequency generation; L, S and C-band synthesisers; and clock recovery in communication systems, mobile terminals, telemetry, radar, and portable radios

The low phase noise FOM of -230dB/Hz in the PE33241 PLL reduces interference, thereby improving the link quality of the communication system. The PLL features a selectable prescaler modulus of 5/6 or 10/11, which provides design flexibility and minimises unwanted frequency spurs. The device supports operation at 5GHz with the 10/11 prescaler modulus, and 4GHz with the 5/6 prescaler 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 80 mA at 2.8V, which reduces thermal issues and extends battery life.
