2520、3225功能引脚

功能引脚示意图	脚位		功能	说明
	1	VIN	Input	0-Vdd: produces voltage dependent frequency change
	2	GND	Power	Electrical ground
	3	CLK	Power	Power supply voltage
	4	VDD	Input Power	Oscillator output power[7]

7. A capacitor value of 0.1 μF between VDD and GND is recommended.

5032、7050功能引脚

功能引脚示意图	脚位		功能	说明
	1	VIN	Input	0-Vdd: produces voltage dependent frequency change
	2	NC/OE/ST	No Connect	H or L or Open: No effect on output frequency or other device functions
			Output Enable	H or Open[8]: specified frequency output  L: output is high
			Standby	H or Open[8]: specified frequency output  L: output is low (weak pull down)[9]. Oscillation stops
	3	GND	Power	Electrical ground
	4	CLK	Output	Oscillator output
	5	NC	No Connect	H or L or Open: No effect on output frequency or other device functions
	6	VDD	Power	Power supply voltage[10]

Notes:
8. In OE or ST mode, a pull-up resistor of 10 kΩ or less is recommended if pin 2 in the 6-pin package is not externally driven. If pin 2 needs to be left floating, use the NC option
9. Typical value of the weak pull-down impedance is 5 mΩ
10. A capacitor value of 0.1 μF between VDD and GND is recommended.
