7Z38400005

TXC Corp · Temperature Compensated Crystal Oscillators (TCXOs) · SMD2016-4P

7Z38400005 from TXC Corp, in a SMD2016-4P. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	AFC	input	Optional voltage-control (AFC) input giving a pull range of +7 to +16 ppm at VC = 2.5 V and -16 to -7 ppm at VC = 0.5 V (reference VC = 1.5 V).
2	GND	power_in	Ground connection; the test diagram routes it to ground.
3	OUTPUT	output	Clipped sinewave output with a minimum 0.8 Vp-p level into a 10 kΩ // 10 pF load, AC-coupled by a 1000 pF capacitor in the test circuit.
4	VCC	power_in	Supply voltage pin, 1.8 to 3.3 V (±5%) with maximum 2.0 mA supply current, and a 10 nF bypass capacitor (C1) should be placed.
