LVCMOS
Serial Data.
In I2C microprocessor control mode (CMODE = 0), this pin func-
tions as the bidirectional serial data port. In SPI microprocessor
control mode (CMODE = 1), this pin functions as the serial data
output.

ILVCMOS
Serial Port Address.
In I2C microprocessor control mode (CMODE = 0), these pins
function as hardware controlled address bits. The I2C address
is 1101 [A2] [A1] [A0]. In SPI microprocessor control mode
(CMODE = 1), these pins are ignored.
This pin has a weak pull-down.

A2_SS
ILVCMOS
Serial Port Address/Slave Select.
In I2C microprocessor control mode (CMODE = 0), this pin func-
tions as a hardware controlled address bit [A2].
In SPI microprocessor control mode (CMODE = 1), this pin
functions as the slave select input.
This pin has a weak pull-down.

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.
