VG7050EAN SM18T009-CJGHPZ3

Overview

The VG7050EAN SM18T009-CJGHPZ3 is a programmable voltage-controlled crystal oscillator (VCXO) manufactured by Epson. It operates within a frequency range of 50 MHz to 800 MHz and utilizes LVPECL output signaling. The device functions at a supply voltage of 3.3V and includes enable/disable control capabilities. It is housed in an 8-SMD, no-lead package. The component supports a total frequency stability of ±50ppm and is rated for operation across an extended temperature range from -40°C to +85°C.

Feature Summary

• Supports programmable frequency generation within the 50 MHz to 800 MHz range
• Features LVPECL output interface for high-speed digital applications
• Includes hardware enable and disable control functionality
• Designed for operation in extended industrial temperature environments

Applications

• High-speed serial communication interfaces
• Network infrastructure equipment requiring precise timing
• Test and measurement instrumentation systems
• Telecommunications base station modules

Procurement Notes

Verify the specific suffix CJGHPZ3 against official Epson documentation to confirm exact factory programming parameters. Ensure compatibility with existing board design regarding LVPECL load requirements and thermal management specifications for the 8-SMD package. Confirm availability status as some variants may be discontinued.

Selection Notes

Select this component when a wide tuning range up to 800 MHz is required alongside strict phase noise performance typical of VCXOs. Consider the LVPECL output drive strength and power consumption at 3.3V relative to system constraints. Evaluate the ±50ppm stability requirement against overall system jitter budget before finalizing the part number selection.

Part Context

This model belongs to the VG7050EAN series of programmable oscillators from Epson Timing. The series offers various output types and frequency ranges tailored for datacom and telecom applications. The specific variant integrates a VCXO architecture allowing for frequency adjustment while maintaining low phase noise characteristics essential for clock distribution networks.

Replacement Considerations

Check Epson's official lifecycle notices for discontinuation status. Identify direct replacements within the VG7050EAN family that match the 8-SMD footprint and LVPECL output. Verify pin-to-pin compatibility and electrical parameter equivalence before substituting.
