Description

External reference crystal input/external reference clock input

3.3 V voltage supply

Serial interface data line/frequency select 0 / VCXO analog control voltage / Output Enable /

Power-down

Ground

Clock output B/frequency select 1/serial interface clock line

Clock output A

Clock output C / frequency select 3 / VSS

External reference crystal output: Connect to external crystal. When the reference is an external

clock signal (applied to pin 1), this pin is not used and must be left floating.
