VG7050EAN SM18T009-DJGHPZB

Overview

The VG7050EAN SM18T009-DJGHPZB is a programmable voltage-controlled crystal oscillator (VCXO) manufactured by Epson. It features an LVPECL output interface and operates within a frequency range of 50 MHz to 800 MHz, adjustable via I2C communication. The device supports a supply voltage of 2.5V and includes enable/disable functionality. It is housed in an 8-SMD, no-lead package and is designed for surface-mount applications.

Feature Summary

• Supports programmable frequency adjustment from 50 MHz to 800 MHz through I2C interface
• Provides LVPECL output signal format for high-speed digital applications
• Includes hardware enable and disable control capabilities

Applications

• High-performance networking equipment requiring precise clock signals
• Telecommunications infrastructure utilizing LVPECL interfaces
• Test and measurement instruments needing programmable frequency sources

Procurement Notes

Verify the specific suffix DJGHPZB against official Epson documentation to confirm the 2.5V supply voltage requirement and LVPECL output configuration. Ensure compatibility with I2C programming protocols before integration. Confirm RoHS compliance status and lead-free specifications match project requirements. Validate that the blank programming type aligns with system firmware capabilities for user-side frequency configuration.

Selection Notes

Select this component when a programmable VCXO with LVPECL outputs is required for frequencies up to 800 MHz. Consider the 2.5V supply constraint and I2C control interface during system design. Evaluate the 8-SMD package dimensions for PCB layout constraints. Ensure the operating temperature range of -40°C to 85°C meets environmental conditions.

Part Context

This part belongs to the VG7050EAN series of programmable oscillators from Epson Timing. The series offers various voltage options and output types, with this specific model focusing on 2.5V operation and LVPECL signaling. It is distinct from other variants like the CJGHPZB which may support different voltages such as 3.3V.

Replacement Considerations

Direct substitutes include other VG7050EAN variants with matching LVPECL outputs and 2.5V supply, such as those with different suffixes if electrical parameters align. Verify pinout and I2C address compatibility when considering alternative Epson models or competitors' programmable VCXOs.
