The 8V97003 is a high-performance wideband microwave Synthesizer / Phase Lock Loop (PLL) that generates output frequencies up to 18GHz from an integrated Voltage Controlled Oscillator (VCO) offering an octave of frequency tuning range. The device  offers a high-performance 32-bit fractional feedback divider and an output divider to allow users to fully benefit from the wideband characteristics of the VCO. The device's industry leading figure of merit and  excellent VCO performance allow for very low phase noise and RMS phase jitter. The 8V97003 offers a very low output-to-output and input-to-output phase skew drift in temperature across the entire temperature range, reducing radio path recalibration occurrences in beamforming applications, such as 5G radio card massive MIMO systems. The output drivers have programmable output power settings and can deliver very high output power to facilitate board layout and contribute to keep excellent signal integrity up to 18GHz. The 8V97003 relies on a single 3.3V power supply and offers low noise integrated LDOs for excellent power supply noise immunity. The device is encapsulated into a 7 × 7mm 48-VFQFN package.
