TX-508 Temperature Controlled Crystal Oscillators (TCXO)

Product catalog summary

Overview: The TX-508 is a Temperature Compensated Crystal Oscillator (TCXO) designed by Vectron International, featuring low G-sensitivity, high shock resistance, and low phase noise. It is suitable for use in portable equipment and land mobile radios.

Frequency Stability: The TX-508 offers frequency stability across a range of operating temperatures from -40°C to +85°C. Standard frequency stability ranges from ±0.5 ppm to ±2.5 ppm, while Stratum 3 TCXO offers stability from ±0.28 ppm to ±0.8 ppm. Initial tolerance and stability against supply voltage, load changes, and aging are specified.

Performance Specifications: The oscillator operates at a supply voltage of 3.3V or 5.0V, with current consumption of 30 mA and 40 mA respectively. It provides an HCMOS RF output with a load capacity of 15 pF and a duty cycle of 40-60%. Frequency tuning options are available with a tuning range of ±5.0 to ±20 ppm.

Environmental Conditions: The TX-508 is designed to withstand random vibrations and shocks as per MIL-STD-202G standards. It operates within a temperature range of -40°C to +85°C and can be stored between -55°C and +105°C.

Phase Noise and Jitter: The oscillator exhibits low phase noise across various offset frequencies, with jitter measured at 0.2 ps RMS from 12 kHz to 20 MHz.

Packaging and Handling: The standard shipping method includes tape and reel packaging, with specific dimensions and quantities per reel. A recommended reflow profile for assembly is provided.

Ordering Information: The product can be customized with options for package type, supply voltage, stability code, frequency control, RF output, and temperature range. Vectron International provides contact information for further inquiries and support.
