Connect to VSS2 with a 1.0μF capacitor that should have the low ESR (Equivalent
Series Resistance) over all temperature range. When this capacitor has the polarity,
the positive polarity pin should be connected to the VSS2 pin. Non polarity capacitors
can also be used.
Connect to CP with a 1.0μF capacitor that should have the low ESR (Equivalent
Series Resistance) over all temperature range. When this capacitor has the polarity,
the positive polarity pin should be connected to the CP pin. Non polarity capacitors
can also be used.
Connect to CN with a 1.0μF capacitor that should have the low ESR (Equivalent
Series Resistance) over all temperature range. When this capacitor has the polarity,
the positive polarity pin should be connected to the CP pin. Non polarity capacitors
can also be used.
An external TTL clock should be input on this pin.
