Description
Pins form an on-chip reference oscillator when connected to
terminals of an external parallel resonant crystal. Xin may be
connected to TTL/CMOS external clock source. If Xin connected
to external clock other than crystal, leave Xout (pin 2)
unconnected.
Digital control inputs to select input frequency range and output
frequency scaling. Refer to Tables 7 & 8 for selection. S0 has
internal pulldown. S1 has internal pullup.

Loop Filter. Single ended tri-state output of the phase detector. A
two-pole passive loop filter is connected to Loop Filter (LF).
Modulated Clock Frequency Output. The center frequency is the
same as the input reference frequency for FS781. Input
frequency is multiplied by 2x and 4x for FS782 and FS784
respectively.
