PD# (Power down) Clarification
The CKPWRGD/PD# pin is a dual-function pin. During initial
power up, the pin functions as CKPWRGD. Once CKPWRGD
has been sampled HIGH by the clock chip, the pin assumes
PD# functionality. The PD# pin is an asynchronous active
LOW input used to shut off all clocks cleanly before shutting
off power to the device. This signal is synchronized internally
to the device before powering down the clock synthesizer. PD#
is also an asynchronous input for powering up the system.
When PD# is asserted LOW, clocks are driven to a LOW value
and held before turning off the VCOs and the crystal oscillator.
PD# (Power down) Assertion
When PD is sampled HIGH by two consecutive rising edges
of CPUC, all single-ended outputs will be held LOW on their
next HIGH-to-LOW transition and differential clocks must held
LOW. When PD mode is desired as the initial power on state,
PD must be asserted HIGH in less than 10
s after asserting
CKPWRGD.
PD# Deassertion
The power up latency is less than 1.8 ms. This is the time from
the deassertion of the PD# pin or the ramping of the power
supply until the time that stable clocks are generated from the
clock chip. All differential outputs stopped in a three-state
condition, resulting from power down are driven high in less
than 300
s of PD# deassertion to a voltage greater than
200 mV. After the clock chip’s internal PLL is powered up and
locked, all outputs are enabled within a few clock cycles of
each clock. Figure 2 is an example showing the relationship of
clocks coming up.
