DESCRIPTION
3.3V PCI clock output or CR#_A input. Default is PCI0. To configure this pin as CR#_A, the PCI output must first be
I/O
disabled in Byte 2, bit 0.
Byte 5, bit 7: 0 = PCI0 enabled (default), 1= CR#_A enabled.
Byte 5, bit 6: 0 = CR#_A controls SRC0 (default), 1= CR#_A# controls SRC2.
PWR Power supply for PCI clocks, nominal 3.3V
3.3V PCI clock output / SRC5 enable strap. On powerup, the logic value on this pin determines if SRC5 or
I/O
CPU_STOP#/PCI_STOP# is enabled. The latched value controls the pin function as follows
0 = PCI_STOP#/CPU_STOP#
1 = SRC5/SRC5#
Free running PCI clock output and ITP/SRC8 enable strap. This output is not affected by the state of the PCI_STOP# pin.
I/O
On powerup, the state of this pin determines whether pins 38 and 39 are an ITP or SRC pair.
0 =SRC8/SRC8#
1 = ITP/ITP#
PWR Ground pin for the PCI outputs
PWR Power pin for the 48MHz output.3.3V
I/O
3.3V tolerant input for CPU frequency selection. Refer to input electrical characteristics for Vil_FS and Vih_FS values. /
Fixed 48MHz USB clock output. 3.3V.
PWR Ground pin for the 48MHz outputs
PWR Power pin for the DOT96 clocks, nominal 1.05V to 3.3V.
True clock of push-pull SRC or DOT96 with integrated series resistor. No 50 ohm pull down needed. Default is SRCT0.
OUT
After powerup, this pin function may be changed to DOT96T via SMBus Byte 1, bit 7 as follows:
0= SRC0T
1=DOT96T
Complementary clock of push-pull SRC or DOT96 with integrated series resistor. No 50 ohm pull down needed. Default is
OUT
SRC0C. After powerup, this pin function may be changed to DOT96C via SMBus Byte 1, bit 7 as follows:
0= SRC0C
1=DOT96C
PWR Ground pin.
PWR Power supply, nominal 3.3V
OUT CK505 Singled Ended Output 1. 3.3V.
PWR Ground pin.
OUT
True clock of differential 0.8V push-pull SRC/SATA output with integrated 33ohm series resistor. No 50ohm resistor to
GND needed.
OUT
Complementary clock of differential 0.8V push-pull SRC/SATA output with integrated 33ohm series resistor. No 50ohm
resistor to GND needed.
PWR Ground pin for the SRC outputs
True clock of push-pull SRC output with int. 33ohm series resistor/CR#_C input. Disable SRC3 via Byte 4, bit 7, before
I/O
using as CR#_C.
Byte 5, bit 3: 0=SRC3 (default), 1=CR#_C.
Byte 5, bit 2: 0=CR#_C controls SRC0 (default), 1=CR#_C controls SRC2
Complementary clock of push-pull SRC output with int. 33ohm series resistor/CR#_D input. Disable SRC3 via Byte 4, bit
I/O
7, before using as CR#_D.
Byte 5, bit 1: 0=SRC3 (default),1=CR#_D.
Byte 5, bit 0: 0=CR#_D controls N/A (default), 1=CR#_D controls SRC4
PWR 1.05V to 3.3V from external power supply
OUT True clock of push-pull SRC output with int. 33ohm series resistor.
OUT Complementary clock of push-pull SRC output with int. 33ohm series resistor.
24 CPU_STOP#/SRCC5_LPR
I/O
Stops all CPUCLK, except those set to be free running clocks /
