Oscillators provide low-cost OCXO performance

Triton combines Rakon's Pluto ASIC compensation technology with simplified oven control to create a hybrid product with near OCXO performance.

Rakon's Triton oven controlled crystal oscillators(OCXOs) bridge the gap between high-end temperature controlled crystal oscillators(TCXOs) and existing low-end OCXOs in terms of stability, size, weight, power consumption and cost.

Triton combines Rakon's Pluto ASIC compensation technology with simplified oven control to create a hybrid product capable of frequency stabilities down to 25 parts per billion over temperature in a small DIP14 package.

Triton products address markets that require near OCXO performance, but without the high cost or power consumption, including high-precision GPS receivers, telecom infrastructure, wireless infrastructure and digital radio transmitter applications.

In Triton OCXOs, a miniature oven keeps the crystal oscillator at an approximately constant temperature slightly above its specified operating temperature range, for example between +90C and +95C for a device with operating temperature range specified as -40C to +85C.

Any residual frequency errors occurring over the oven's limited temperature range are then minimised using the Pluto ASIC's analogue compensation circuitry.

The result is an oscillator with overall stability nearly an order of magnitude better than the most stable TCXOs, comparable to an OCXO but with lower power consumption, a smaller and lighter package and faster warm-up.

The Triton range is initially available at 10, 12.8 and 20MHz, with HCMOS output, but can be customised to customer requirements.
