SimPLL is a comprehensive PLL
design and analysis package. With SimPLL you can rapidly
design your PLL and accurately predict phase noise, lock
times, worst case reference spurs, lock detect performance and
more. It is easy to compare chips, loop filters (even
fast lock options) and more
The SimPLL designer
wizard will have your PLL designed to your requirements in under a minute. SimPLL has libraries of PLL IC data for many standard
chips so you won't have to scour the manufacturer's data sheet for key
SimPLL provides an interactive
design and analysis environment in which you can optimize your
design. Investigate the transient response and phase noise as
you vary the phase margin. Try out different loop
filters, passive and active. Try different op amps and
see the effects on phase noise and reference spurs. Watch how
non-linear effects such as charge pump voltage clipping and phase detector
cycle slipping alter the transient response. Alter your
lock-detect circuit and see the response time. Compare analog and
digital lock detect options. Watch the ACI or residual FM
change as you alter the loop bandwidth. See op-amp bias
currents affect the ref spurs, try out fast lock techniques - on the
computer not on the prototype.
is likely to pay for itself with the first PLL you design as it typically
removes at least one design iteration.
SimPLL you have a real chance of getting most PLL designs right first time
- even the tough ones!
SimPLL works. It
is based on the in-house PLL simulation tools which we have developed
during many years of PLL design at Applied Radio Labs. The
fast simulation core uses sophisticated algorithms that provide accurate
results with real time interactivity.
