Description
1
CLKIN or X1
I
Crystal connection or external reference frequency input. This pin has
dual functions. It can be connected to either an external crystal or an
external reference clock.
Crystal connection. Connection for an external crystal. If using an
external reference, this pin must be left unconnected.
2
NC OR X2
O
3
GND
G
Ground to entire chip.
4
SS%
I
Modulation width selection. When spread spectrum feature is turned
on, this pin is used to select the amount of variation and peak EMI
reduction that is desired on the output signal. Internal pull-up resistor.
5
CLKOUT
O
Output modulated frequency. Copy of the un-modulated input clock.
6
VDD
P
Power supply for the entire chip (3.3V).
7
FS1
I
Frequency selection bit 1. This pin selects the frequency range of
operation. (
Refer to the Frequency Range Selection Table
). This pin
has an internal pull-up resistor.
