Pin Description
Pin Name
Type
Description
XIN
I
Connection to crystal or external reference frequency input. This pin has dual
functions. It can be connected either to an external crystal or an external
reference clock.
XOUT
O
Connection to crystal. If using an external reference clock, this pin must be left
unconnected.
V
DD
P
Power supply for the analog and digital blocks
V
SS
P
Ground to entire chip.
PWDNB
I
Power-down control pin. Pull low to enable the power-down mode. Connect to
VDD, if not used.
SSONB
I
Digital logic input used to enable spread spectrum function (Active LOW).
Spread spectrum is enabled when LOW, disabled when HIGH.
USB Clock
