Oven Controlled SAW Oscillators Grade D are designed for airborne applications. The ULN OCSO are housed in ruggedized packaging including vibration and shock absorbers in order to withstand the harsh environment of airborne radars. The key component of this family of products is the high-reliability SAW resonator housed in an All Quartz Package (AQP) featuring excellent performances in terms of frequency stability, ageing, g-sensitivity.
These oscillators perform the same electrical function as Grade B fundamental mode but for airborne environment (extended temperature range, vibrations, shocks, etc.)
Additional features are offered like PLL on external 10MHz reference, frequency multiplication by 2 or 4.
Digital PLL option is implemented in SR D02 and SR E02.
