ADF4108BRUZ PLL Frequency Synthesizer

GENERAL DESCRIPTION
The ADF4108 frequency synthesizer can be used to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters. It consists of a low noise digital PFD (phase frequency detector), a precision charge pump, a programmable reference divider, programmable A and B counters, and a dual-modulus prescaler (P/P + 1). The A (6-bit) and B (13-bit) counters, in conjunction with the dual modulus prescaler (P/P + 1), implement an N divider (N = BP + A). In addition, the 14-bit reference counter (R counter), allows selectable REFIN frequencies at the PFD input. A complete phase-locked loop (PLL) can be implemented if the synthesizer is used with an external loop filter and voltage controlled oscillator (VCO). Its very high bandwidth means that frequency doublers can be eliminated in many high frequency systems, simplifying system architecture and reducing cost.

FEATURES
8.0 GHz bandwidth
3.2 V to 3.6 V power supply
Separate charge pump supply (VP) allows extended tuning voltage in 3.3 V systems
Programmable, dual modulus prescaler 8/9, 16/17, 32/33, or 64/65
Programmable charge pump currents
Programmable antibacklash pulse width
3-wire serial interface
Analog and digital lock detect
Hardware and software power-down mode
Loop filter design possible with ADIsimPLL

APPLICATIONS
Broadband wireless access
Satellite systems
Instrumentation
Wireless LANs
Base stations for wireless radio
