The ADF5355 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. The wideband microwave VCO design permits frequency operation from 6.8 to 13.6 GHz at one radio frequency (RF) output. Control of all on-chip registers is through a simple 3-wire interface.
The ADF4355-2 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. ADF4355-2 has an integrated VCO with a fundamental output frequency ranging from 3400 MHz to 6800 MHz. The VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32, or 64 circuits.
