OUT

Oscillator clock output. When interfacing to an MCU’s XTAL input, the CLK

Out is typically connected to the receiving IC’s X IN pin.

Vdd

Power Supply

Connect to power supply 1.5V

≤ Vdd ≤ 3.63V. Under normal operating

conditions, Vdd does not require external bypass/decoupling capacitor(s).

Internal power supply filtering will reject more than ±150 mVpp with frequency

components through 10 MHz.

Table 3. Absolute Maximum

Attempted operation outside the absolute maximum ratings cause permanent damage to the part. Actual performance of the

IC is only guaranteed within the operational specifications, not at absolute maximum ratings.
