SEL

IPD

Select control

When this pin is low, the device is controlled via hardware pins,

IN_SEL0/1 and OE_TYPE0/1.

When this pin is high, the device is controlled via I2C Bus port.

Any change of SEL pin value requires power cycle. Hence, SEL pin

cannot be changed on the fly.

This pin is pulled down with 100 kΩ resistor.

OUT_IMP_SEL

IPD

Output Impedance Select

When this pin is low, the output differential impedance is 100Ω

When this pin is high, the output differential impedance is 85Ω

This pin is pulled down with 100 kΩ resistor.

VDD

Positive Supply Voltage

Connect to 3.3V, 2.5V, or 1.8V supply.

VDDO

Positive Supply Voltage for Differential Outputs

Connect to 3.3V, 2.5V, or 1.8V power supply. These pins power up

differential outputs OUT[11:0]_p/n.

VPP

Positive Supply Voltage for Programming OTP Memory

This pin is used for generating custom configurations on ATE. Connect to

ground for normal operation.
