Intel manual Itanium 2 Processor Package Specifications

	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.
