GENERAL DESCRIPTION
FEATURES
The ADF4360-2 is a fully integrated integer-N
synthesizer and voltage controlled oscillator (VCO). The
ADF4360-2 is designed for a center frequency of
2000MHz. In addition, there is a divide-by-2 option
available, whereby the user gets an RF output of between
900MHz and 1075MHz.
Output Frequency Range: 1800 MHz to 2150 MHz
Divide-by-2 output
+3.0 V to +3.6V Power Supply
1.8 V Logic Compatibility
Integer-N Synthesizer
Programmable Dual Modulus Prescaler
8/9, 16/17, 32/33
Programmable Output Power Level
3-Wire Serial Interface
Analog and Digital Lock Detect
Hardware and Software Power Down Mode
Control of all the on-chip registers is via a simple 3-wire
interface. The device operates with a power supply rang-
ing from 3.0V to 3.6V and can be powered down when not
in use.
