This compact TCXO is a temperature-compensated crystal oscillator designed to provide a stable 26.0MHz reference in a tiny surface-mount footprint.
It uses a clipped sine wave output and runs from a 1.8V supply, making it suited to space-constrained RF, timing and embedded electronics designs that need good frequency stability across temperature.
The oscillator comes in a 1.65 x 1.25mm surface mount package for direct assembly onto a PCB. A datasheet is available from the manufacturer for footprint and integration details.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
- Tolerance
- Tolerance tells you how far the real resistance value may be from the printed value. A 1% resistor is useful when a circuit needs more predictable behaviour than a looser 5% or 10% part.
