KVG Quartz Crystal Technology offers new designs for high stable OCXOs in standard cases 36 x 27 mm (CO-08), 25 x 25 mm (through-hole) and 25 x 22 mm (SMD), which meet the frequency stability requirements according to the ANSI Stratum 3E standard.
Based on the latest OCXO developments, KVG says it has now developed new high stable solutions by means of improved designs and by using SC-cut crystals, which will considerably enlarge the applications of OCXOs.
The new designs offer temperature stabilities which are better than ±5 ppb from
-20 to 70°C with ageing rates of ±1 ppb per day and better than ±0,1 ppm per year and meet high requirements of modern applications. So the OCXO series 3000; 4000 and 6000 do now also meet the requirements of frequency stability according to Telcordia (Bellcore) 1244-CORE Stratum 3E, GR-253-CORE (Issue 3) and ITU-T G.812 (option 3); ie, a frequency stability better than ±4,6 ppm over 20 years and - which is notable - a 24 hours holdover-stability of better than ±10 ppb.
These OCXOs are available with supply voltage +5 V or +3,3 V (optionally also +12 V), possible output signals are sine wave or HCMOS. Besides the typical standard frequencies like 10 MHz, 12,8 MHz, 16,384 MHz, 19,44 MHz; 20 MHz and 25 MHz special frequencies are also possible.
Typical applications are network and synchronisation components and systems for professional telecommunication, and measurement equipments and systems for net monitoring.
