10 / 16 page 10 ICS9148-02 PD# Timing Diagram The power down selection is used to put the part into a very low power state without turning off the power to the part. PD# is an asynchronous active low input. This signal is synchronized internal by the ICS9148-02 prior to its control action of powering down the clock synthesizer. Internal clocks will not be running after the device is put in power down state. When PD# is active (low) all clocks are driven to a low state and held prior to turning off the VCOs and the Crystal oscillator. The power on latency is guaranteed to be less than 3mS. The power down latency is less than three CPUCLK cycles. PCI_STOP# and CPU_STOP# are dont care signals during the power down operations. Notes: 1. All timing is referenced to the Internal CPUCLK (defined as inside the ICS9148 device). 2. PD# is an asynchronous input and metastable conditions may exist. This signal is synchronized inside the ICS9148. 3. The shaded sections on the VCO and the Crystal signals indicate an active clock is being generated. Notes: 1. All timing is referenced to the Internal CPUCLK (defined as inside the ICS9148 device.) 2. PCI_STOP# is an asynchronous input, and metastable conditions may exist. This signal is required to be synchronized inside the ICS9148. 3. All other clocks continue to run undisturbed. 4. PD# and CPU_STOP# are shown in a high (true) state. |
