C3VFSE7

Oscillators Overview

The C3VFSE7 is a Voltage Controlled Crystal Oscillator (VCXO) manufactured by Cardinal Components Inc. It operates at a fundamental frequency of 311.04 MHz with a frequency stability of ±30ppm. The device utilizes PECL output signaling and requires a 3.3V supply voltage, drawing a maximum supply current of 100mA. It features an Enable/Disable function for power management. The component is housed in a 6-SMD, No Lead package with dimensions of 7.00mm x 5.00mm and a maximum height of 2.00mm. It supports an operating temperature range of -10°C to 85°C.

Oscillators Feature Summary

• Generates a stable 311.04 MHz clock signal using VCXO technology
• Outputs signals via PECL interface standard
• Includes hardware control for enabling or disabling the oscillator output

Oscillators Applications

• High-speed serial communication interfaces requiring precise clocking

• Data acquisition systems needing low-jitter timing sources

Oscillators Procurement Notes

Verify the specific revision level and pinout configuration against the official datasheet before integration. Confirm that the 3.3V logic levels are compatible with the receiving circuitry. Ensure thermal management strategies account for the 100mA maximum current draw during continuous operation. Check for any specific handling requirements related to the surface-mount package type.

Oscillators Selection Notes

Select this component when a high-frequency VCXO solution is required for applications demanding ±30ppm stability. The PECL output makes it suitable for differential signaling environments. Consider the -10°C to 85°C temperature range for suitability in industrial or commercial settings. Evaluate the 6-SMD footprint constraints against the PCB layout design.

Oscillators Part Context

This part belongs to the family of voltage-controlled crystal oscillators designed for precision timing applications. It offers a fixed frequency output with voltage-tunable capabilities, distinguishing it from standard fixed-frequency oscillators. The PECL output stage provides high-speed performance suitable for demanding digital systems.

Oscillators Replacement Considerations

Direct substitutes may include other 311.04 MHz VCXOs with PECL outputs and similar package dimensions. Verify electrical compatibility, specifically supply voltage and current consumption, when evaluating alternative vendors. Ensure the replacement maintains the required frequency stability and operating temperature range.
