Note: 1. Oscillator output signal. When interfacing to an MCU’s XTAL, the CLK Out is typically connected to the
Receiving IC’s XIN pin. Oscillator includes an internal driver. The output swing and operation is not dependent on capacitive
loading.
2. Connect to supply voltage 1.5V≤Vs≤3.63V for operation over -40°C to +85°C temperature range. Under normal operation
Conditions, Vs does not require external bypass/ decoupling capacitor(s). Internal power supply filtering will reject more than
±150mV p-p with frequency components through 10MHz.
