Feedback Input: This input must be fed by one of the outputs (OUT1 or OUT2) to ensure
proper functionality. If the trace between FBIN and the output pin being used for feedback
is equal in length to the traces between the outputs and the signal destinations, then the
signals received at the destinations are synchronized to the REF signal input (REF_IN).
Reference Input: The output signals are synchronized to this signal.
Negative supply voltage; Connect to ground, 0 V
Function Select Input: Tie to V
Function Select Input: Tie to V
Output 1: The frequency of the signal provided by this pin is determined by the feedback
signal connected to FBIN, and the FS0:1 inputs (see Table 1).
Positive supply voltage This pin should be bypassed with a 0.1 mF decoupling capacitor.
Use ferrite beads to help reduce noise for optimal jitter performance.
Output 2: The frequency of the signal provided by this pin is one−half of the frequency of
OUT1. See Table 1.
