No load condition, f = 20 MHz, Vdd = 2.5V, 2.8V or 3.3V

No load condition, f = 20 MHz, Vdd = 1.8V

Vdd = 2.5V, 2.8V, 3.3V, ST = GND, output is Weakly Pulled Down

Vdd = 1.8V, ST = GND, output is Weakly Pulled Down

See the Absolute Pull Range and APR table on

page 10

Vdd = 1.8V, Voltage at which maximum deviation is guaranteed.

Vdd = 2.5V, Voltage at which maximum deviation is guaranteed.

Vdd = 2.8V, Voltage at which maximum deviation is guaranteed.

Vdd = 3.3V, Voltage at which maximum deviation is guaranteed.

Voltage at which minimum deviation is guaranteed.
