3.3 V CMOS
REF_SEL
Reference Select. This pin selects REF1 (low) or REF2 (high) and has an internal 30 k
pull-down resistor.
8
I
3.3 V CMOS
SYNC
Manual Synchronization and Manual Holdover. This pin initiates a manual
synchronization and is used for manual holdover. Active low. This pin has an
internal 30 k pull-up resistor.
9
I
Loop filter
LF
Loop Filter (Input). This pin connects internally to the VCO control voltage node.
10
O
Loop filter
BYPASS
This pin is for bypassing the LDO to ground with a 220 nF capacitor. It can be left
unconnected if the PLL is not used.

I
Differential
clock input
CLK
Along with CLK, this pin is the differential input for the clock distribution section. If a
single-ended input is connected to the CLK pin, connect a 0.1 F bypass capacitor from
this pin to ground.
