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.
