1/2
Xin/Xout
I/O
Analog
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 (pin2) unconnected.
7/3
S0/S1
I
CMOS/TTL
Digital control inputs to select input frequency range and output frequency scaling. Refer to
Tables 7 and 8 for selection. S0 has internal pulldown. S1 has internal pullup.
4
LF
I
Analog
Loop Filter. Single ended tri-state output of the phase detector. A two-pole passive loop filter is
connected to Loop Filter (LF).
6
FSOUT
O
CMOS/TTL
Modulated Clock Frequency Output. The center frequency is the same as the input reference
frequency for FS781. Input frequency is multipled by 2X and 4X for FS782 and FS784
respectively.
