Name
Type
Description
1
VDDA
PWR
Analog Power Supply.
2
GNDA
PWR
Analog Ground.
3
NC
No connect.
4
GND
GND
Ground.
5
SS_EN
I
Spread spectrum enable pin. 0 = –0.25% spread, mid= Off, 1= –0.5% spread (This
pin has an internal 100 kΩ pull-up).
6
PWRGD/
PWRDNb
I, PU
Active low input pin asserts power down (PDb) and disables all outputs (This pin
has an internal 100 kΩ pull-up). Refer also to settings of Byte 2, Bit2 and Bit3 for
REF. Settings for Bit3 (REF_OE) will take precedence for REF.
7
GND
GND
Ground.
8
XIN/CLKIN
I
25.00 MHz crystal input or 25 MHz Clock Input.
9
XOUT
O
25.00 MHz crystal output. Float XOUT if using only CLKIN (Clock input).
10
VDDX
PWR
Power supply for crystal.
11
VDDR
PWR
Power supply for REF output.
12
REF /SA
O/I
REF = 25 MHz LVCMOS output. SA = Address select for I2C. When part is pow-
ered up, SA will be latched to select the I2C address. Refer to Table 8.1 SA State
on First Application of PWRGD/PWRDNb on page 32. Refer also to 5.14 REF/SA
Pin for termination. (This pin has an internal 60 kΩ pull-up.)
