Power Supply
No Connect. Will not respond to any input signal. When interfacing to an MCU’s XTAL
input pins, this pin is typically connected to the receiving IC’s X Out pin. In this case,
the MT-9560A will not be affected by the signal on this pin. If not interfacing to an XTAL
oscillator, leave pin 1 floating (no connect).
Connect to ground. All GND pins must be connected to power supply ground. The GND
pins on the SOT23 and CSP packages can be connected together, as long as both GND pins
are connected ground.
Oscillator clock output. When interfacing to an MCU’s XTAL, the CLK Out is typically
connected to the receiving IC’s X IN pin. The MT-9560A oscillator output includes an
internal driver. As a result, the output swing and operation is not dependent on capacitive
loading. This makes the output much more flexible, layout independent, and robust
under changing environmental and manufacturing conditions.
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 500 mVpp with frequency components through 10 MHz. Contact
factory for applications that require a wider operating supply voltage range.
