ELECTRICAL CHARACTERISTICS - REF-14.318MHZ

Following Conditions Apply Unless Otherwise Specified:

Operating Condition: TA = 0°C to +70°C, Supply Voltage: VDD = 3.3V ± 5%; CL = 10 - 20pF

NOTE:

1.

This parameter is guaranteed by design, but not 100% production tested.

PCI STOP FUNCTIONALITY

If PCIF (2:0) and SRC clocks are set to be free-running through SMBus programming, they will ignore the PCI_STOP register bit.
