The SFOUT [1:0] pins can also be used to disable both outputs. Disabling the output puts the CKOUTn+ and
CKOUTn– pins in a high-impedance state relative to V
(common mode tri-state) while the two outputs remain
DD
connected to each other through a 200  on-chip resistance (differential impedance of 200 ). The maximum
amount of internal circuitry is powered down, minimizing power consumption and noise generation. Recovery from
the disable mode requires additional time as specified in Table 3, “AC Characteristics”.
