DESCRIPTION
29
*CLKREQC#
IN
Output enable for PCI Express (SRC) outputs. SMBus selects which outputs are controlled.
0 = enabled, 1 = tri-stated
30
ATIGCLKC1
OUT
Complementary clock of differential ATIGCLK clock pair.
31
ATIGCLKT1
OUT
True clock of differential ATIGCLK clock pair.
32
GNDATIG
PWR
Ground for ATIG clocks
33
VDDATIG
PWR
Power supply ATIG clocks, nominal 3.3V
34
ATIGCLKC0
OUT
Complementary clock of differential ATIGCLK clock pair.
35
ATIGCLKT0
OUT
True clock of differential ATIGCLK clock pair.
36
VDDSRC
PWR
Supply for SRC clocks, 3.3V nominal
37
GNDSRC
PWR
Ground pin for the SRC outputs
38
SRCCLKC0
OUT
Complement clock of differential SRC clock pair.
39
SRCCLKT0
OUT
True clock of differential SRC clock pair.
40
IREF
OUT
This pin establishes the reference current for the differential current-mode output pairs. This
pin requires a fixed precision resistor tied to ground in order to establish the appropriate
current. 475 ohms is the standard value.
41
GNDA
PWR
Ground pin for the PLL core.
42
VDDA
PWR
3.3V power for the PLL core.
43
CPUCLK8C1
OUT
Complementary clock of differential 3.3V push-pull K8 pair.
44
CPUCLK8T1
OUT
True clock of differential 3.3V push-pull K8 pair.
45
GNDCPU
PWR
Ground pin for the CPU outputs
46
VDDCPU
PWR
Supply for CPU clocks, 3.3V nominal
47
CPUCLK8C0
OUT
Complementary clock of differential 3.3V push-pull K8 pair.
48
CPUCLK8T0
OUT
True clock of differential 3.3V push-pull K8 pair.
49
*CLKREQA#
IN
Output enable for PCI Express (SRC) outputs. SMBus selects which outputs are controlled.
0 = enabled, 1 = tri-stated
50
GNDHTT
PWR
Ground pin for the HTT outputs
51
HTTCLK0
OUT
3.3V Hyper Transport output
52
VDDHTT
PWR

I/O
Frequency select latch input pin / 14.318 MHz reference clock.
56
FS0/REF0
I/O
Frequency select latch input pin / 14.318 MHz reference clock.
