circuit, PCI bridge chip and the LOCAL_PCI_RESET# logic
circuitry. The BD_SEL# signal is connected to the ON pin
while the PWRGD pin is connected to the HEALTHY#
signal. The HEATHLY# signal is combined with the
PCI_RESET# signal to generate the LOCAL_PCI_RESET#
signal. Capacitors C6 and C7 provide chip bypassing on
the 12V and 12V inputs. Diode D2 protects the part from
voltage surges below 13.2V on the 12V supply.
The 1V precharge voltage for the data bus lines is gener-
ated by an LT1117 low dropout regulator. The output of the
LT1117 is set to 1.8V, then the voltage is dropped by a
1N4148 diode to generate 1V. The precharge circuit is
capable of sourcing and sinking 40mA.

Figure 7. Typical CompactPCI Application
LTC1643AL-1
The LTC1643AL-1 is designed for CompactPCI designs
where the ?2V supplies are not being used on the board
or the supplies are not well regulated. The power good
comparators on the 12V
OUT
and V
EEOUT
pins are disabled.
The V
EEIN
pin can be connected to GND and the part will
still operate normally if a 12V
OUT
output is not needed.
However, 12V is still required at the 12V
IN
pin for the part
to function. Refer to Figure 10 for a typical LTC1643AL-1
application circuit.
