Z-Communications, Inc. Introduces Rugged 100 MHz OCXO Reference For Demanding Lab And Field Applications

Z-Communications, Inc., a leader in advanced frequency generation technology, today announced the launch of its new Oven Controlled Crystal Oscillator (OCXO) Reference, the REF100ECA-O. Engineered to deliver ultra-low phase noise and superior frequency stability, this compact 100 MHz reference is designed for high-performance laboratory testing and demanding in-field system applications.

The REF100ECA-O features an exceptional phase noise profile of -156 dBc/Hz at a 10 kHz offset, dropping to a floor of -170 dBc/Hz at 1 MHz. It provides a steady +7.5 dBm sine wave power output with a tight frequency stability of ±50 ppb across a wide operating temperature range from -40°C to +85°C. Packaged in a rugged, all-metal enclosure, the device is built to withstand harsh environments while offering a flexible, single wide-range supply voltage from 7 to 18 Vdc.

“Modern test systems and field operations demand highly reliable reference signals that don’t compromise on signal purity,” said the Applications Engineering Team at Z- Communications. “The REF100ECA-O bridges the gap between delicate benchtop performance and extreme field reliability, giving engineers a dependable 100 MHz reference wherever they need it.”

Built for Extreme Durability
Unlike standard laboratory references, the internal OCXO of the REF100ECA-O was tested to comply with stringent military standards.

• Shock Resistance: Meets MIL-STD-202G, Method 213, Test Condition C.
• Random Vibration: Meets MIL-STD-810G, Method 514, Test Procedure I.
• Sinusoidal Vibration: Meets MIL-STD-202G, Method 204, Test Condition A.

Key Technical Specifications

• Output Frequency: 100 MHz (Sine wave)
• Phase Noise: -156 dBc/Hz at a 10 kHz offset
• Power Output: +7.5 dBm into a 50 Ω load impedance
• Frequency Stability vs. Temp: ±50 ppb
• Aging Rate: ±1 ppb per day
• Spurious Suppression: -80 dB
