New temperature compensated oscillators to be seen at PCB Live exhibition

New from Golledge Electronics and on show at the forthcoming PCB Live exhibition on March 12th are two new temperature compensated oscillators. They are likely to be of especial interest to designers in the transportation sector because both products are available with optional EN50155 compliance: the international standard for electronics equipment used on rolling stock in the rail industry.

Golledge’s new GTXO-251T TCXO is an ultra-miniature 2.5 x 2.0 x 0.8mm component offering excellent stability down to ±0.5ppm: and it can be specified in several operating temperature options, offering a variety of choices between a low of -40° Celsius to maximum of +85°Celsius.

The company’s GTXO-251V is a new compensated oscillator with voltage controlled frequency adjustment, and is available with two voltage control options. Designers can choose from either the standard ±8ppm ~ ±14ppm, 1.5V ±1.0V, or alternatively a wide pullability option of ±15ppm ~ ±25ppm. This makes it an excellent choice for some AIS applications which require wider voltage controlled frequency adjustment.

Both the GTXO-251T and the GTXO-251V are designed to operate at any voltage across the 1.8V ~ 3.3V range, and users can specify a test voltage to ensure suitability and confirm performance data for specific applications.

Both the GTXO-251V and GTXO-251T, together with a wide selection of other premium quality components from Golledge, will be available to view on the company’s stand at PCB Live 2020.


PCB Live is the UK’s only dedicated event focusing on PCB design, test and manufacture. This one-day opportunity provides senior engineers with a platform to meet and talk with some of the most experienced PCB-related technologists and application experts in the country.
