FX-702-SYNCE-156M250000 Datasheet, PDF (6/7 Pages) Vectron International, Inc – Complete VCSO Based Phase Lock Loop

Application Circuits
The FX-702 includes a phase detector, charge pump, frequency dividers and a VCSO with its own an associated divide-by function.
The addition of the simple external loop filter shown below completes the design of this low jitter VCXO based PLL.
The above circuit has a 300 Hz loop bandwidth.
