Ultra-Stable Performance with the FO0907L OCXO
Oven-controlled stability usually comes in a bulky package. The FO0907L OCXO from FCD-Tech B.V. brings ppb-level temperature stability and a −155 dBc/Hz phase noise floor to a 9 x 7 mm SMD footprint, ready for standard reflow assembly and space-constrained boards.
Key Specifications & Performance Features
Designed as a compact frequency reference for systems that cannot tolerate drift, the FO0907L covers 5 to 50 MHz, with 10 MHz and 40 MHz as nominal frequencies.
Key advantages include:
- Ultra-Stable Over Temperature: ±5 ppb from −20 °C to +70 °C and ±10 ppb across the full −45 °C to +85 °C range.
- Low Phase Noise: −135 dBc/Hz at 100 Hz, −150 dBc/Hz at 1 kHz and −155 dBc/Hz at 10 kHz offset at 10 MHz.
- Low Aging and Sensitivity: ±2 ppb per day, with supply and load sensitivity each held within ±2 ppb.
- HCMOS Output: 3.3 V supply, 45–55% duty cycle and 5 ns maximum rise/fall time into 15 pF.
- Electronic Tuning: ±0.5 to ±2.0 ppm EFC range with positive slope for disciplined or PLL-locked designs.
- Qualified Build: Temperature and mechanical stress tested to IEC 60068 and GJB360B, RoHS compliant.
Applications
Telecom base stations, test and measurement instrumentation, GNSS-disciplined timing, network synchronization and precision frequency synthesis.
