VG7050EAN SM18T005-CJGHPF0

Overview

The VG7050EAN SM18T005-CJGHPF0 is a programmable Voltage-Controlled Crystal Oscillator (VCXO) manufactured by Seiko Epson Corporation. It operates within a frequency range of 50 MHz to 800 MHz and utilizes LVPECL output signaling. The device supports a supply voltage of 3.3V and features enable/disable functionality. It offers a total frequency stability of ±50ppm and functions across an operating temperature range of -40°C to +85°C. The maximum supply current is 90mA. The component is housed in an 8-SMD, No Lead package.

Feature Summary

• Programmable VCXO architecture requiring user-defined configuration
• LVPECL differential output interface for high-speed signal integrity
• Wide operational temperature range suitable for industrial environments
• Integrated enable and disable control function

Applications

• Telecommunications base station synchronization
• High-speed data transmission equipment clocking
• Industrial control system timing references
• Network infrastructure signal generation

Procurement Notes

Verify the specific suffix code CJGHPF0 against official Seiko Epson documentation to confirm exact frequency and pinout specifications. Ensure compatibility with 3.3V logic levels and LVPECL termination requirements. Confirm that the blank programmable type aligns with your programming tool capabilities. Check for any last-time-buy status indicators associated with this specific revision.

Selection Notes

Select this component when a wide tunable frequency range between 50 MHz and 800 MHz is required with precise ±50ppm stability. The LVPECL output is ideal for noise-sensitive high-speed digital interfaces. Consider the 8-SMD no-lead package for surface-mount assembly constraints. Evaluate the -40°C to +85°C rating against environmental conditions. Ensure the 90mA max current draw fits within the power budget.

Part Context

This part belongs to the VG7050 series of programmable oscillators from Seiko Epson. The series is designed for applications demanding flexible frequency generation with high stability. The VG7050EAN variant specifically denotes the package and thermal characteristics. Other suffixes may indicate different frequencies or packaging options within the same functional family.

Replacement Considerations

Direct substitutes are not explicitly listed in public datasheets for this exact suffix. Cross-reference with other VG7050 series variants such as VG7050EAN SM18T005-CJGHPF3 if frequency or package differences are acceptable. Verify electrical compatibility before substitution.

FAQ
