The AS1153 is a voltage-controlled oscillator (VCO) IC designed and manufactured by ams, a publicly-traded semiconductor producer specializing in analog, mixed-signal and power management solutions. Its maximum input voltage range is up to 8 volts, while its maximum output frequency range is up to 10GHz. Specifically, the AS1153 is suitable for a wide range of frequency control applications, operating from 0 to five GHz. The chip facilitates the simple low pass filtering necessary for a stable, reliable and frequency accurate signal. The AS1153 also features low phase noise and a high level of immunity to supply, reactance and load impedance variations, resulting in reduced currents in the control port.
