CKOUT3+
CKOUT3–
OMULTI
Clock Output 3.
Differential clock output. Output signal format is selected by
SFOUT3_REG register bits. Output is differential for LVPECL,
LVDS, and CML compatible modes. For CMOS format, both
output pins drive identical single-ended clock outputs.

CKOUT1–
CKOUT1+
OMULTI
Clock Output 1.
Differential clock output. Output signal format is selected by
SFOUT1_REG register bits. Output is differential for LVPECL,
LVDS, and CML compatible modes. For CMOS format, both
output pins drive identical single-ended clock outputs.

FS_OUT–
FS_OUT+
OMULTI
Frame Sync Output.
Differential frame sync output or fifth high-speed clock output.
Output signal format is selected by SFOUT_FSYNC_REG reg-
ister bits. Output is differential for LVPECL, LVDS, and CML
compatible modes. For CMOS format, both output pins drive
identical single-ended clock outputs. Duty cycle and active
polarity are controlled by FSYNC_PW and FSYNC_POL bits,
respectively. Detailed operations and timing characteristics for
these pins may be found in the Any-Frequency Precision Clock
Family Reference Manual.

LVCMOS
Control Mode.
Selects I2C or SPI control mode for the device.
0=I2C Control Mode.
1 = SPI Control Mode.
This pin must be tied high or low.

CKOUT2+
CKOUT2–
OMULTI
Clock Output 2.
Differential clock output. Output signal format is selected by
SFOUT2_REG register bits. Output is differential for LVPECL,
LVDS, and CML compatible modes. For CMOS format, both
output pins drive identical single-ended clock outputs.

CKOUT4–
CKOUT4+
OMULTI
Clock Output 4.
Differential clock output. Output signal format is selected by
SFOUT4_REG register bits. Output is differential for LVPECL,
LVDS, and CML compatible modes. For CMOS format, both
output pins drive identical single-ended clock outputs.
GND PAD
GND
Supply
Ground Pad.
The ground pad must provide a low thermal and electrical
impedance to a ground plane.
