ADF4351/ADF4350 Frequency Source PLL RF Source V2025 35Mhz-4.4GHz Frequency Generator (ADF4350 137.5M-4.4G +STM32)

The ADF4351 has an integrated voltage controlled oscillator (VCO) with a fundamental output frequency ranging from 2200 MHz to 4400 MHz, In addition, divide-by-1/-2/-4/-8/-16/-32/-64 circuits allow the user to generate RF output frequencies as low as 35 MHz.; For applications that require isolation, the RF output stage can be muted, The mute function is both pin- and software-controllable.; An auxiliary RF output is also available, which can be powered down when not in use. Control of all on-chip registers is through a simple 3-wire interface.; The device operates with a power supply ranging from 3.0 V to 3.6V and can be powered down when not in use.

; The ADF435l allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and external reference frequency.;
APPLICATIONS: Wire less infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT); Test equipment; Wire less LANs, CATV equipment; Clock generation.
