PX-340

Product catalog summary

Overview: The PX-340 is a precision crystal oscillator designed by Vectron International, featuring a miniature hybrid design and a 14-pin flatpack. It supports a frequency range from 1 Hz to 125 MHz and offers output options in ACMOS and TTL.

Performance Specifications:

Frequency Stability: The oscillator provides various stability options depending on the operating temperature range, with stability values ranging from ±5 ppm to ±300 ppm.
Initial Tolerance: Ranges from ±1 ppm to ±50 ppm at +25°C, with custom options available.
Aging: Frequency stability due to aging is ±3 ppm for the first year and ±2 ppm for subsequent years.
Supply Voltage: Standard supply voltage is 5.0 VDC, with an option for 3.3 VDC for frequencies below 20 MHz.

RF Output Specifications:

Signal Levels: Varies with supply voltage, with typical values of 0.5 VDC for low and 4.5 VDC for high at 5.0 VDC supply.
Rise and Fall Times: Varies with frequency, ranging from 3 ns to 10 ns for ACMOS signals.
Duty Cycle: Ranges from 40% to 60% depending on frequency.

Screen Testing: The PX-340 undergoes various screen tests as per MIL-STD-883 standards, with different classes (X, B, S) offering varying levels of testing rigor, including stabilization bake, seal test, temperature cycling, and burn-in.

Ordering Information: The product can be customized with various options for temperature range, accuracy, stability, and screening levels. Customers are advised to contact the factory for specific requirements and availability.
