Spread Spectrum Clock Synthesizer
Note:
1. Please note that all clocks can also be individually (asynchronously) enabled or stopped
via the 2-wire I
2
C control interface. In this case all clocks are stopped in the low state.
Figure 1. PD# Timing Diagram
Power Management Timing
When MODE = 0, the device supports power management and pin
11 is input PD#. When MODE = 1, this function is not available).
A particular output is enabled only when both the I
2
C serial
interface and this pin indicate that it should be enabled. The clocks
may be disabled according to the following table in order to reduce
the power consumption. All clocks are stopped in the low state.
PCI_F
PD#
PCI (1:5)
CPU (0:1)
A
B
A: Represents one PCI clock wait cycle
B: Represents one CPU clock wait cycle
All clocks maintain a valid high period on transitions from running
to stopped. The CPU and PCI clocks transition between running and
stopped by waiting for one positive edge on PCI_F followed by a
negative edge on the clock of interest, after which high levels of the
outputs are either enabled or disabled. See Figure 1 below.
