Electronics Thermal management OCXO RFX satellite temperature thermal managementRFX Group PT560-10-GPS surface mount OCXO range features a long term satellite locked temperature stability combined with a 20% reduction in both footprint and height. Operating at 10MHz, product offers a GPS locked long term temperature stability of ±0.001ppb or reverts to ±20ppb over –40 to 70 degrees C if unlocked. Delivering a 7dBm Sinewave output from 5Vdc supply, load change performance has also improved from ±10ppb down to ±5ppb based on a 10% load change whilst the new package now measures 24.2 x 22.5mm with a height of only 9.1mm. Device utilizes an SC-cut crystal optimized for low noise which alongside other design characteristics gives far-out phase noise down to -168dBc/Hz at 100KHz and close-in phase noise at 120dBc/Hz at 10Hz. Device also meets vibration, mechanical and thermal shock to MIL standard 202F and is fully RoHS compliant.
