**TAE(Zhejiang Abel Elec)** · Oscillators · SMD3225-4P

TFOM8M4RHKCNT2T from TAE(Zhejiang Abel Elec), in a SMD3225-4P. 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 | E/D (Tri-state) | input | Tri-state enable/disable control: open or high gives oscillation output, low puts the output in high impedance (output disable time 100 nsec, enable time 10 msec max). |
| 2 | GND | power_in | Ground connection. |
| 3 | OUT | output | CMOS clock output at 8.000MHz, Voh 90%Vdd min, Vol 10%Vdd max, 15pF max load. |
| 4 | VDD | power_in | Power supply of 1.8V-5V±10% with 5mA max input current. |
