Fractional-N PLL frequency synthesizer integrates a low noise VCO for 1815 MHz to 2010 MHz RF output operation. It supports 3 Hz typical resolution with a 24-bit fractional step size, exact frequency mode, cycle slip prevention, and built-in digital self test. The device uses 3.3 V analog and digital supplies plus 5 V analog supplies for the charge pump, VCO core, and RF buffer sections. Operation is specified from -40°C to +85°C in a RoHS-compliant 40-lead 6 mm by 6 mm SMT plastic package.
