Unused
No connect.

LOCK
Output
Lock indicator. When HIGH, the PLL is frequency locked to a valid input
reference. LVCMOS/LVTTL interface levels.
3
REF_FAIL
Output
Reference fail indicator. A logic HIGH at this output indicates that the reference
(REF) frequency is exhibiting abrupt phase or frequency change.
LVCMOS/LVTTL interface levels.
4, 5, 8, 27, 31
GND
Power
Power supply ground.
9
nRST
Input
Pullup
Reset. A logic LOW at this input resets the device. In Reset state, all outputs are
forced into high-impedance. LVCMOS/LVTTL interface levels.
10
OSCo
Output
Crystal out.
11
OSCi
Input
Crystal in or single ended clock input.
12, 14, 30
VDD
Power
Core supply pins.
13
FIL_OUT
Output
Filter output pin connected to 4.7F capacitor.
18, 21
VDDA
Power
Analog supply pins.
19
C65o
Output
Single-ended clock output, 65.536MHz frequency. This output is used for
general TDM applications. LVCMOS/LVTTL interface levels.
26
C25o
Output
Single-ended clock output, 25MHz frequency. This is a buffered version of
internal crystal oscillator. The phase and frequency accuracy of this output
tracks that of the external crystal or oscillator.
LVCMOS/LVTTL interface levels.
28
REF
Input
Pulldown
This is the input reference source used for synchronization. LVCMOS/LVTTL
interface levels.
