RF PLL Frequency Synthesizers

ADF4116/ADF4117/ADF4118

GENERAL DESCRIPTION

FEATURES

ADF4116: 550 MHz

ADF4117: 1.2 GHz

ADF4118: 3.0 GHz

The ADF411x family of frequency synthesizers can be used to

implement local oscillators (LO) in the upconversion and

downconversion sections of wireless receivers and transmitters.

They consist of a low noise digital phase frequency detector

(PFD), a precision charge pump, a programmable reference

divider, programmable A and B counters, and a dual-modulus

prescaler (P/P + 1). The A (5-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 REF_INfrequencies

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).

2.7 V to 5.5 V power supply

Separate V_Pallows extended tuning voltage in 3 V systems

Y Grade: −40°C to +125°C

APPLICATIONS

All of the on-chip registers are controlled 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.
