FX-700 Theory of Operation

The FX-700 includes an integrated phase detector, current mode charge pump, programmable frequency dividers and VCXO. The

FX-700 will translate an input frequency such as 8 kHz, 1.544 MHz or 19.440 MHz to a speciﬁc output frequency which is an integer

multiple (1-16384) of the input frequency and less than or equal to 77.760 MHz. For clock smoothing applications, the input

frequency is typically internally divided down by a factor of 64 (2N where N = 6) by the input frequency divider and this frequency

becomes an input to the phase detector. The integrated frequency dividers (factory programmed) and crystal based VCXO allows

for a large range of possible frequency translations and clock smoothing applications.

The FX-700’s PLL is a feedback system which forces the output frequency to lock in both phase and frequency to the input

frequency. While there will be some phase error, theory states there is no frequency error. The loop ﬁlter design will dictate many

key parameters such as jitter reduction, stability, lock range and acquisition time. The external second order passive loop ﬁlter is

a complex impedance in parallel with the input capacitance of the VCXO. The loop ﬁlter converts the charge pump output into

the VCXO’s control voltage. VI’s loop ﬁlter design methodology involves the calculation of the open loop gain bandwidth and

corresponding phase margin to determine the optimal component values that ensure high loop stability and acceptable lock in

time. As a rule of thumb, the VCXO gain is typically 100 ppm/volt and the charge pump current is typically 32 uA.

VI’s Applications Engineering staﬀ can provide the external loop ﬁlter component values required to meet speciﬁc system

requirements and application.
