Usage Notes:

The regulator LED may not illuminate unless there is a load from the PMC on the 3.3V
supply, and the regulator is selected as the power source for the 3.3V.
The Regulator path can provide up to 1500 mA of 3.3V power. Two FET's are used to
allow the user to select PCI 3.3V or local regulator as the source for the 3.3V power to
the PMC. If the PMC uses more than 1.5A the PCI selection must be made.
The FET has a small internal resistance and the protection DIODE has a separate
current sensitive drop. For low current levels the IR drop is small and the 3.3 will be
with the legal range. For larger current levels the –HC option should be selected to
minimize the voltage drop.
Jumper options are clearly marked in the component side silk screen.
J1 3.3V Source selector. open = regulated, installed = PCI source.
J2 Connected to pins 33, 67 on P2. 1-2 = 5V, 2-3 = GND installed with –SCSI
J3 Connected to pins 34, 68 on P2. 1-2 = 5V, 2-3 = GND installed with -SCSI
J4 Connected to M66EN. Installed = GND = 33 MHz. Open = bus condition = 33 or 66
MHz.
J5 is the JTAG Header with options for connection to PCI bus or from Flying leads.

The header can be jumpered across to connect the PCI side to the PMC side or the
PMC side can be connected to flying leads from your JTAG interface.
J8 Pin 1 = 3.3, and pin 2 = gnd used for reference with JTAG
Add –JTAG to the Part Number if you need J5 and J8 installed.
