PIN DESCRIPTIONS
INPUT PINS
fin
Frequency Input (Pin 8)
Input frequency from VCO output. A rising edge signal on
this input decrements the
÷
A and
÷
N counters. This input
has an inverter biased in the linear region to allow use with
ac coupled signals as low as 500 mV p–p. For larger ampli-
tude signals (standard CMOS logic levels), dc coupling may
be used.
CLK, DATA
Shift Clock, Serial Data Inputs (Pins 9, 10)
Each low–to–high transition of the CLK shifts one bit of
data into the on–chip shift registers. The last data bit entered
determines which counter storage latch is activated; a logic 1
selects the reference counter latch and a logic 0 selects the
÷
A,
÷
N counter latch. The data entry format is as follows:

ENB
Latch Enable Input (Pin 11)
A logic high on this pin latches the data from the shift regis-
ter into the reference divider or
÷
N,
÷
A latches depending on
the control bit. The reference divider latches are activated if
the control bit is at a logic high and the
÷
N,
÷
A latches are
activated if the control bit is at a logic low. A logic low on this
pin allows the user to change the data in the shift registers
without affecting the counters. ENB is normally low and is
pulsed high to transfer data to the latches.
OSCin, OSCout
Reference Oscillator Input/Output (Pins 1, 2)
These pins form an on–chip reference oscillator when con-
nected to terminals of an external parallel resonant crystal.
Frequency setting capacitors of appropriate value must be
connected from OSCin to ground and OSCout to ground.
OSCin may also serve as the input for an externally–gener-
ated reference signal. This signal is typically ac coupled to
OSCin, but for larger amplitude signals (standard CMOS log-
ic levels) dc coupling may also be used. In the external refer-
ence mode, no connection is required to OSCout.
