Device features low phase noise Figure of Merit and supports operation at 5 GHz
Peregrine Semiconductor 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 -230 dBc/Hz, which improves the signal-to-noise ratio, thereby helping to reduce the overall system cost while improving performance. The device supports operation at 5 GHz with a 10/11 prescaler modulus, making it ideal for industrial transceivers, specialized transceivers, and clock generators requiring low phase noise. The PE33241 PLL is ideal for RF frequency generation; L, S and C-band synthesizers; and clock recovery in communication systems, mobile terminals, telemetry, radar, and portable radios.
The low phase noise FOM of –230 dB/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 minimizes unwanted frequency spurs. The device supports operation at 5 GHz with the 10/11 prescaler modulus, and 4 GHz 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.

Development Tool Support
Peregrine also unveiled the PE33241 Evaluation Kit today, to enable designers to evaluate the new PLL in their applications. The kit has a USB-to-Serial programming interface to allow customers to easily control the PLL. It can be ordered in late June, from Peregrine’s global direct sales representatives and worldwide distribution partners.
Packaging, Pricing & Availability
The PE33241 Integer-N PLL is available in a 7 mm × 7 mm 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, from Peregrine’s global direct sales representatives, and worldwide distribution partners
