is
set
by
UCD9222
configuration file.
5
VCC1V8 (DSP IO power)
5ms
Turn on VCC1V8 after VCC1V0 is stable
for 5ms.
6
CDCE62005#2 initiations
FPGA 1.8V outputs
5ms
Unlock
1.8V
outputs
and
initiate
CDCE62005 after VCC1V8 is stable for
5ms by de-asserting power down (PD#)
pins.
7
VCC1V5 (DSP DDR3 power)
5ms
Turn on VCC1V5 5ms after the initiation
of CDCE62005.
8
VCC0V75
5ms
Turn on VCC0V75 after VCC1V5 is stable
for 5ms.
When VCC1V5 is valid, FPGA de-asserts
the power down pin of IDT5V41068, PCIe
clock multiplexor.
When VCC0V75 is valid, FPGA enables
mux clock outputs asserting OE pin.
9
RESETz
Other reset and NMI pins
5ms
De-asserts RESETz and unlocks other
reset and NMI pins for DSP after
VCC0V75 is stable and CDCE62005 PLL
locked for 5ms.
In the meanwhile, FPGA will drive the
boot configurations to DSP GPIO pins.
10
PORz
5ms
De-asserts PORz after RESETz is de-
asserted for 5ms.
11
RESETFULLz
5ms
De-asserts RESETFULLz after PORz is
de-asserted for 5ms.
12
DSP GPIO pins for boot
configurations
1ms
Releases
DSP
GPIO
pins
after
RESETFULLz is de-asserted for 1ms
Power-Down
13
RESETFULLz
PORz
0ms
If there is a power failure or AMC payload
is
powered
off,
FPGA
will
assert
RESETFULLz and PORz signals to DSP.
14
FPGA 1.8V outputs
CDCE62005 PD# pins
5ms
Locks 1.8V output pins on FPGA and pull
CDCE62005 PD# pin to low to disable
DSP clocks
15
CVDD
VCC1V0
VCC1V8
VCC1V5
VCC0V75
VCC2V5
IDT5V41068 PD# and OE
0ms
Turns off all main power rails.
