功能引脚示意图 | 脚位 | 功能 | 说明 | |
1 | NC | No Connect | 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 SiT1533 will not be affected by the signal on this pin. If not interfacing to an XTAL oscillator, leave pin 1 floating (no connect). | |
2 | GND |
Power Supply
Ground
|
Connect to ground. All GND pins must be connected to power supply ground. | |
3 | CLK Out | OUT |
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 SiT1533 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.

|
4 | VDD | Power Supply | Connect to power supply 1.5V ≤ Vdd ≤ 3.63V for operation over -40°C to +85°C temperature range. 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. |
