New PLLs from Peregrine Semiconductor operate in 50 MHz to 3.5 GHz range

Peregrine Semiconductor has introduced two new devices the PE33361 Integer-N PLL and the PE33631 Delta-Sigma Modulated (DSM) Fractional-N PLL in its Phase-Locked Loop (PLL) frequency synthesizer family. Peregrine said these are the first devices to be completely developed through Peregrine's recently announced European design and manufacturing flow. These UltraCMOS RFIC devices are targeted for military, broadband cable infrastructure, and wireless infrastructure markets. The PLLs operate over a frequency range 50 MHz to 3.5 GHz, providing a high-performance RF solution for applications such as cellular base stations, CATV set-top boxes, test and measurement equipment, WiMax-based communications systems and point-to-point radios where system scalablility is key to improving designs.

These new PLL devices deliver frequency synthesis up to 3.5 GHz with -216dBc/Hz phase noise (normalized), and ultra-low power consumption of 40 mA in the case of PE33631 and 45 mA in PE3336 at 3.3V. Both PLL devices offer flexible programming options. The PE33361 PLL is programmable through serial, parallel and direct mode access and the PE33631 PLL is programmable through serial and direct mode access. It has an Electro-Static Discharge (ESD) tolerance is 1000 V HBM. The devices feature a ÷10/11 dual modulus prescaler, which enables high divide ratios in applications requiring low phase-detector comparison frequencies. It also has an internal phase-frequency detector that generates up and down frequency control signals, and provides a phase comparator and phase counter values, which are programmable. The PE33631 adds a delta-sigma modulator, which maintains fine frequency resolution while eliminating fractional spurs in the output.

Package:
The PE33361 is packaged in the compact 48-lead 7x7mm QFN.
The PE33631 is packaged in the robust 64-lead 9x9mm QFN.

Price:
The PE33361 -- each US$11.52 for 25k units.
The PE33631 -- each US$12.80 for 25k units.
