Frequency Select Pin (FSA, FSB and FSC)
Apply the appropriate logic levels to FSA, FSB, and FSC
inputs before CKPWRGD assertion to achieve host clock
frequency selection. When the clock chip sampled HIGH on
CKPWRGD and indicates that VTT voltage is stable then FSA,
FSB, and FSC input values are sampled. This process
employs a one-shot functionality and once the CKPWRGD
sampled a valid HIGH, all other FSA, FSB, FSC, and
CKPWRGD transitions are ignored except in test mode.
Serial Data Interface
To enhance the flexibility and function of the clock synthesizer,
a two-signal serial interface is provided. Through the Serial
Data Interface, various device functions, such as individual

VDD_CPU
PWR
3.3V Power supply for CPU PLL.
56
CKPWRGD/PD#
I
3.3V LVTTL input. This pin is a level sensitive strobe used to latch the FS_A, FS_B,
FS_C, FS_D, SRC5_SEL, and ITP_EN.
After CKPWRGD (active HIGH) assertion, this pin becomes a real-time input for
asserting power down (active LOW).
57
FSB/TEST_MODE
I
3.3V tolerant input for CPU frequency selection.
Selects Ref/N or Tri-state when in test mode
0 = Tri-state, 1 = Ref/N.
Refer to DC Electrical Specifications table for Vil_FS and Vih_FS specifications.

VSS_REF
GND
Ground for outputs.

XOUT
O, SE 14.318MHz Crystal output. (Float XOUT if using CLKIN)

XIN/CLKIN
I
14.318MHz Crystal input or 3.3V, 14.318MHz input clock signal.
61
VDD_REF
PWR
3.3V Power supply for outputs and also maintains SMBUS registers during
power-down.
62
REF0/FSC/TEST_SEL
I/O
3.3V tolerant input for CPU frequency selection/fixed 14.318MHz clock output.
Selects test mode if pulled to VIHFS_C when CKPWRGD is asserted HIGH. Refer
to DC Electrical Specifications table for VILFS_C, VIMFS_C, VIHFS_C specifications.
