# 8W01200600

**TXC Corp** · Programmable Oscillators · SMD2520-4P

8W01200600 from TXC Corp, in a SMD2520-4P. 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 | OE | input | Enable/disable pin: high (or open) gives normal oscillator output, low gives high-impedance output and stops oscillation; VIH min 70%Vdd, VIL max 30%Vdd. |
| 2 | GND | power_in | Ground connection. |
| 3 | OUTPUT | output | CMOS clock output, drives 15 pF load, high impedance when OE is low. |
| 4 | VDD | power_in | Supply voltage pin of 1.8, 2.5 or 3.3 V (±10%). |
