1. A broadband phase-locked loop chip with integrated VCO, delivering superior performance. 2. High phase discrimination frequency reduces phase noise, while a low-pass filter suppresses VCO noise and shortens locking time. 3. The chip operates in integer and fractional frequency division modes, with precise frequency setting in decimal mode, enabling accurate acquisition of specific frequencies. 4. This phase-locked loop chip boasts industry-leading low phase noise and spurs, with precise frequency setting allowing for very small output frequency steps to achieve 0 Hz frequency error. 5. With best-in-class noise performance and spurs, this signal module excels when high signal quality and signal-to-noise ratio are required. 6. The signal source module's application market includes broadband multi-carrier, multi-standard mobile base station equipment up and down conversion, serving as a low jitter clock local oscillator generator, or as an adjustable reference source for obtaining spur-free signals. It can also be used in high Quadrature Amplitude Modulation microwave point-to-point communication, software radio, and test and measurement equipment.
