ADF4360-0

Data Sheet Integrated Synthesizer and VCO ADF4360-0 FEATURES GENERAL DESCRIPTION Output frequency range: 2400 MHz to 2725 MHz Divide-by-2 output 3.0 V to 3.6 V power supply 1.8 V logic compatibility Integer-N synthesizer Programmable dual-modulus prescaler 16/17, 32/33 Programmable output power level 3-wire serial interface Analog and digital lock detect Hardware and software power-down mode APPLICATIONS The ADF4360-0 is a fully integrated integer-N synthesizer and voltage-controlled oscillator (VCO). The ADF4360-0 is designed for a center frequency of 2600 MHz. In addition, a divide-by-2 option is available, whereby the user gets an RF output of between 1200 MHz and 1360 MHz. Control of all the on-chip registers is through a simple 3-wire interface. The device operates with a power supply ranging from 3.0 V to 3.6 V and can be powered down when not in use.
