GENERAL DESCRIPTION
The ADF4360-6 is a fully integrated integer-N synthesizer and voltage-controlled oscillator (VCO). The ADF4360-6 is designed for a center frequency of 1150 MHz. In addition, a divide-by-2 option is available, whereby the user receives an RF output of between 525 MHz and 625 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.

APPLICATIONS
Wireless handsets (DECT, GSM, PCS, DCS, WCDMA) Test equipment Wireless LANs CATV equipment
