Description
I/O
I/O circuit
HCTR
70
Input
Universal counter input.
Input must be supplied through a coupling capacitor.
The input frequency range is 0.4 to 12 MHz
This pin can be used effectively for FM IF or AM IF
counting.
Universal counter input.
ADI
69
Input
A/D converter input.
This converter requires 1.28 ms to perform a 6-bit
sequential comparison conversion.
Full scale (a data value of 3F (hexadecimal))
corresponds to (63/96) time V
DD
.
LCTR
71
Input must be supplied through a coupling capacitor
when the input frequency is in the range 100 to
500 kHz.
No input coupling capacitor is required when the input
frequency is in the range 1 Hz to 20 kHz.
This pin can be used effectively for AM IF counting.
This pin can also be used as a normal input port.
INT
66
Input
External interrupt request input.
An interrupt occurs when the INTEN flag is set with the
SS instruction and a falling edge is input.
This pin can also be used as a normal input port.
EO1
EO2
77
78
Output
These pins are used as the reference frequency output
and the phase comparator error output for the
programmable divider.
A charge pump circuit is built in.
EO1 and EO2 are the same.
SNS
72
Input
Input used to recognize power failures when the IC is in
backup mode.
This pin can also be used as a normal input port.
HOLD
67
Input
Input used to set the IC to hold mode.
The IC switches to hold mode when the HOLDEN flag
is set with the SS instruction and the HOLD pin is set
low.
A high-voltage handling circuit is used so that this pin
can be linked to the power switch in typical systems.
RES
68
Input
System reset input.
Applications must hold this input low for at least 75 ms
to effect a power on reset.
To start a reset, this pin must be held low for a full 6
base clock cycles.
XIN
XOUT
1
80
Input
Output
Crystal oscillator connections
(4.5 MHz)
Feedback resistors are built in.
