Filter Selector (Input). Logic 0 on this pin sets the filter corner frequency to
1.5 Hz, this selection meets requirements of G.813 option 1 and GR-1244 Stratum
3 clocks. Logic 1 on this pin sets the filter corner frequency to 0.1 Hz, this selection
meets requirements of G.813 option 2, GR-253 for SONET Stratum 3 and GR-253
for SONET Minimum Clocks (SMC).
Oscillator Out (Output). This output provides access to the internal 20 MHz
TCXO and will normally be connected to the OSCi pin.
Oscillator In (Input). This is the master 20 MHz clock input pin and is normally
connected directly to the OSCo (internal TXCO) pin. However, this input can be
connected to an external 20 MHz reference if required. If an external reference is
going to be used, then the TV
unconnected; this will save on power and reduce any unwanted noise.
