ADF4110/ADF4111/ADF4112/ADF4113
FEATURES
GENERAL DESCRIPTION
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 3 V systems
Programmable dual-modulus prescaler 8/9, 16/17, 32/33,
64/65
The ADF4110 family of frequency synthesizers can be used to
implement local oscillators in the upconversion and downcon-
version sections of wireless receivers and transmitters. They
consist 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
Programmable charge pump currents
(P/P + 1). The A (6-bit) and B (13-bit) counters, in conjunction
Programmable antibacklash pulse width
with the dual-modulus prescaler (P/P + 1), implement an N
3-wire serial interface
Analog and digital lock detect
Hardware and software power-down mode
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
APPLICATIONS
Base stations for wireless radio (GSM, PCS, DCS, CDMA,
if the synthesizer is used with an external loop filter and voltage
controlled oscillator (VCO).
WCDMA)
Wireless handsets (GSM, PCS, DCS, CDMA, WCDMA)
Wireless LANS
Communications test equipment
Control of all the on-chip registers is via a simple 3-wire
interface. The devices operate with a power supply ranging
from 2.7 V to 5.5 V and can be powered down when not in use.
