Analogue, Mixed Signal, LSI
Claimed to be the industry's first 8 GHz phase-locked loop (PLL) synthesizer, the ADF4108 from Analog Devices, is targeted at high-frequency wireless systems, such as those used for broadband wireless access, satellite communications, instrumentation, wireless LANs and base stations for wireless radio. Because of its high-frequency operation, the chip eliminates the need for frequency doublers, simplifying system architecture and reducing system cost.
Showcased at this year's IEEE MTT-S International Microwave Symposium, the ADF4108 deepens Analog Devices' broad range of RF ICs and technologies, which includes direct digital synthesizers; PLL synthesizers; detectors and logarithmic amplifiers; fixed and variable gain amplifiers; mixers, modulators, and demodulators; integrated IF amplifiers; RF transmitters and transceivers, and the Othello family of single-chip transceivers for cellular terminals. Analog Devices also offers ADIsimPLL, a most comprehensive PLL circuit design and evaluation tool, while its ADIismLINK is a development tool for users of the company's ISM band transceivers for short range wireless connectivity.
The 8 GHz ADF4108 PLL synthesizer consists of a low-noise digital PFD (phase frequency detector), a precision charge pump, a programmable reference divider, programmable A (6-bit) and B (13-bit) counters, and a dual-modulus prescaler (P/P + 1). It has a power supply range of 3,2-3,6 V.
