ADF4112BRUZ RF PLL Frequency Synthesizers

GENERAL DESCRIPTION
The ADF4110 familyoffrequency synthesizers can be used to implement localoscillators inthe upconversion and downcon version sectionsofwireless receivers and transmitters. They
consistofalownoise digitalPFD(phasefrequencydetector), a precisionchargepump, a programmablereference 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 withthe dual-modulus prescaler (P/P + 1),implement an N divider(N = BP+ A).Inaddition,the 14-bitreference counter(R counter) allows selectable REFIN frequencies atthe PFD input. A completephase-lockedloop(PLL) can be implemented ifthe synthesizer is used with an external loopfilter and voltage
controlledoscillator (VCO).

FEATURES
ADF4110: 550 MHz; ADF4111:1.2 GHz; ADF4112: 3.0 GHz; ADF4113: 4.0 GHz
2.7 V to 5.5 V power supply
Separate charge pump supply (VP) allows extended tuning voltage in 3V systems
Programmable dual-modulus prescaler 8/9, 16/17, 32/33, 64/65
Programmable charge pump currents
Programmable antibacklash pulse width
3-wire serial interface
Analogand digital lock detect
Hardware and software power-down mode

APPLICATIONS
Base stations for wireless radio (GSM, PCS, DCS, CDMA, WCDMA)
Wireless handsets (GSM, PCS, DCS, CDMA, WCDMA)
Wireless LANS
Communications test equipment
CATVequipment
