CFSE7

Oscillators Overview

The CFSE7 is a surface-mount crystal oscillator (XO) manufactured by Cardinal Components Inc. It operates at a nominal frequency of 622.08 MHz with a CMOS output interface. The device features a frequency stability of ±30 ppm and supports a supply voltage range typical for this series, housed in a compact SMD package suitable for high-speed digital applications requiring precise clock signals.

Oscillators Feature Summary

• Generates a stable 622.08 MHz clock signal using CMOS logic levels
• Provides tight frequency stability of ±30 ppm for reliable synchronization
• Designed for surface-mount assembly to support automated manufacturing processes

Oscillators Applications

• High-speed serial communication interfaces requiring precise timing
• Network infrastructure equipment utilizing OC-12/STM-4 standards
• Test and measurement instruments demanding low-jitter clock sources

Oscillators Procurement Notes

Verify the specific operating temperature range and supply voltage requirements against your system design before procurement. Confirm that the CMOS output voltage levels are compatible with the receiving logic inputs. Ensure the surface-mount footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during operation.

Oscillators Selection Notes

Select the CFSE7 when a fixed 622.08 MHz frequency is required with moderate stability needs. This component is suitable for designs where CMOS outputs are preferred over LVDS or PECL due to power or compatibility constraints. Consider the ±30 ppm stability as sufficient for standard telecommunications protocols without requiring higher-grade oven-controlled oscillators.

Oscillators Part Context

This part belongs to the Crystal Oscillator (XO) category within Cardinal Components' portfolio. It serves as a fixed-frequency clock source, distinct from programmable or voltage-controlled variants. The CFSE7 provides a standardized solution for applications needing a dedicated, unchangeable clock signal at the 622.08 MHz rate.
