Electrical Specifications

VCTERM

System bus termination voltage.

GND

System ground.

N/C

No connection can be made to these pins.

TERMA, TERMB

The Itanium 2 processor uses two pins to control the on-die termination

 

function, TERMA and TERMB. Both of these termination pins must be

 

pulled to VCTERM in order to terminate the system bus using the on-die

 

termination resistors. Both of these termination pins must be pulled to

 

GND in order to use off-die termination.

TUNER1, TUNER2

TUNER1 is used to control the slew rate of the system bus I/O buffers.

 

The nominal value for the TUNER1 resistor is 150 ohms. A lower

 

resistance will cause a faster slew rate. TUNER2 is used to control the

 

termination resistance for the system bus I/O buffers. The nominal value

 

for the TUNER2 resistor is 150 ohms. A lower resistance will cause a

 

lower on-die termination resistance. On-die termination mode will only

 

be selected if the TERMA and TERMB pins are terminated as indicated

 

above.

VCCMON, VSSMON

These pins provide a remote sense connection from the processor to the

 

power pod. No connections that constitute a current load can be made to

 

these pins.

2.3Package Specifications

Table 2-2through Table 2-9list the DC voltage, current and power specifications for the Itanium 2 processor. The voltage and current specifications are defined at the Itanium 2 processor pins. Operational specifications listed in Table 2-2through Table 2-9are only valid while meeting specifications for case temperature, clock frequency, and input voltages.
