Benefits
The Philsar PS2500 provides has the following benefits:
Small step size allows for higher internal reference frequency which permits a lower multiplication ratio
improving phase noise.
Lower phase noise permits the use of a wider loop filter bandwidth, which in turn yields a faster
frequency switching and acquisition time.
Small step size allows flexibility in choosing a reference crystal or oscillator frequency, as very narrow
channel spacing can be supported.
The on-chip oscillator permits use of a crystal instead of a crystal oscillator lowering the system cost.
Programmable phase detector gain allows for variable loop filer bandwidths. Frequency switching and
acquisition times can be improved by opening up the bandwidth, and subsequently lower phase noise
contribution can be achieved by narrowing down the loop filter bandwidth after phase lock.
Programmable power-down modes optimize power management.
Individually configurable main and auxiliary synthesizers as integer-N, allowing a reduction in power
consumption.
Configurable resolution of the main
Σ
modulator from 18 to 10 bits, allowing further reduction in
power consumption.
