Capacitance
Power-up Sequence Requirements
 Upon power-up, all the outputs remain three-stated until all 
the V
pins
have powered-up to the nominal voltage and 
the part has completed configuration.
 The part will not start configuration until V
CC
, V
CCIO
, 
V
CCJTAG
, V
CCCNFG
, V
CCPLL
 and V
CCPRG
 have reached 
nominal voltage.
 V
CC 
pins can be powered up in any order. This includes 
V
CC
, V
CCIO
, V
CCJTAG
, V
CCCNFG
, V
CCPLL
 and V
CCPRG
.
 All V
s on a bank should be tied to the same potential 
and powered up together.
 All V
s (even the unused banks) need to be powered up 
to at least 1.5V before configuration has completed.
 Maximum ramp time for all V
CC
s should be 0V to nominal 
voltage in 100 ms.
Notes:
9.
PCI spec (rev 2.2) requires the IDSEL pin to have capacitance less than or equal to 8 pF. Delta39K Pin Tables starting from page 45, identify all the I/O pins in 
a given package, which can be used as IDSEL in a PCI design. All other I/O pins meet the PCI requirement of capacitance less than or equal to 10 pf.
10. The number of I/Os which can be used in each I/O bank depends on the type of I/O standards and the number of V
CCIO
 and GND pins being used. Please refer 
to the application note titled 
“Delta39K and Quantum38K I/O Standards and Configurations”
 for details.
The source current limit per I/O bank per Vccio pin is 165 mA.
The sink current limit per I/O bank per GND pin is 230 mA.
11.
See “Power-up Sequence Requirements” below for V
CCIO
 requirement.
12. 25W resistor terminated to termination voltage of 1.5V.
