Fractional-N PLL frequency synthesizer integrates a low-noise VCO with a doubled RF output covering 3.365 GHz to 3.705 GHz. The device supports fine frequency resolution with a 24-bit fractional architecture, exact-frequency mode, cycle-slip prevention, and built-in digital self test. Supply rails include 3.3 V analog and digital domains plus 5 V analog charge-pump, VCO, and buffer supplies. The RoHS-compliant 40-lead 6 mm × 6 mm SMT package operates from -40°C to +85°C and has MSL1 moisture sensitivity.
