Pin Description
Crystal or ceramic resonator output pin. Leave this pin unconnected
(floating) if external clock is used at Pin-3.
Crystal, ceramic resonator or external clock input pin.
User Programmable PD# or OE control pin. Power Down (PD#-Active
Low): If PD#=0(Low), the device is powered down and both SSCLK and
REFOUT outputs are weakly pulled low to VSS. Output Enable (OE-
Active High): If OE=1(High), the SSCLK and REFOUT outputs are
enabled.
PD# or OE is weakly pulled high to VDD.

Programmable SSON# or Frequency Select (FS) Control pin. If SSCG#
function is programmed: Spread-on=0(Low) or Spread-off=1(High). If FS
function is programmed: The clock frequencies can be switched between
two sets of frequencies as programmed.
SSON# or FS is weakly pulled low to VSS.
