OX-501 Oven Controlled Crystal Oscillators (OCXO)

Product catalog summary

Product Overview: The OX-501 is an Oven Controlled Crystal Oscillator (OCXO) designed for applications requiring high stability and precision. It is available in a 6-pin SMD package and offers fast warm-up times, making it suitable as a TCXO replacement for improved short-term stability. The frequency range is from 10 MHz to 100 MHz, with standard frequencies including 10, 12.8, 16.384, 19.44, 20, 30.72, 38.88, and 51.84 MHz.

Applications: The OX-501 is ideal for use in base stations, test equipment, femto base stations, and military communication equipment.

Frequency Stability: The document details frequency stabilities for both AT-Cut and SC-Cut crystals. For AT-Cut crystals (7 to 20 MHz), stability ranges from -100 to +250 ppb over various temperature ranges. SC-Cut crystals (20 to 40 MHz) offer stability from -30 to +50 ppb. Initial tolerance, supply voltage change, load change, and aging effects are specified, with warm-up times of 2 minutes to reach ±200 ppb for AT-Cut and ±100 ppb for SC-Cut crystals.

Performance Specifications: The supply voltage is standard at 3.3 VDC, with power consumption of 2.2 Watts during warm-up and 0.7 Watts steady state at +25°C. The RF output is HCMOS with a load of 15 pF, and the duty cycle is between 45% and 55%. Frequency tuning options are available with tuning ranges specified for both AT and SC cut crystals.

Additional Parameters: Phase noise is detailed at various offsets, with values ranging from -65 dBc/Hz at 1 Hz to -145 dBc/Hz at 10 kHz. The oscillator weighs 8.0 grams.

Handling and Processing: Absolute maximum ratings include a supply voltage of 5.5 V and an operable temperature range from -55°C to +85°C. The recommended reflow profile for assembly is provided, with specific temperature and time guidelines.

Ordering Information: The document provides a detailed breakdown of the ordering code structure, including product family, package type, height, supply voltage, stability code, frequency, frequency control, RF output code, and temperature range.
