OCXO
Stability at Near TCXO Power, Size and Cost
Rakon’s Triton oven
controlled oscillators, bridge the gap between high end TCXOs and low end OCXOs
in terms of stability, size, weight, power consumption and of course, cost.
Rakon’s ultra stable crystal oscillator products offer the highest frequency
stability performance achievable from a TCXO. These TCXOs address markets
that require near OCXO performance, but without the high cost or power
consumption. The Triton™ product family combines proprietary Pluto ASIC
compensation technology with simplified oven control to create a hybrid
product capable of stabilities down to 25ppb (2.5 x 10-8) over
temperature, in small DIP14 packages.
The Triton uses a miniature oven with simplified temperature control to keep
the crystal oscillator at an approximately constant temperature slightly
above its specified operating temperature range- e.g between 90°C and 95°C
for a device with operating temperature range specified as -40°C to +85°C.
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- i.e comparable to that of an
OCXO- but with lower power consumption, smaller and lighter package size and
faster warm-up. In addition, rate of frequency change over temperature is
better than that of high performance TCXOs. The Triton is initially available
in 10, 12.8 and 20MHz, with HCMOS output, but can be customized to your
requirement.
Suitable for Precision GPS Receivers, Telecom infrastructure, Wireless
(Femtocell, Picocell, WiMax) infrastructure, and Digital Radio transmitter
applications. Sampling is available now with production quantities available
September 2007.
