VG7050EAN SM18T003-CJGLPZ3

Overview

The VG7050EAN SM18T003-CJGLPZ3 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 the LVPECL output interface. The device supports a supply voltage of 3.3V and features an enable/disable control function. It is housed in an 8-SMD, no-lead package and is designed for operation across a temperature range of -40°C to +85°C. Key electrical specifications include a maximum current consumption of 90mA during active operation and a reduced current of 40mA in disable mode. The unit offers a frequency stability of ±50ppm.

Feature Summary

• Supports programmable frequency generation from 50 MHz to 800 MHz
• Features LVPECL output interface for high-speed digital applications
• Includes hardware enable and disable control functionality
• Designed for industrial temperature ranges with low power consumption

Applications

• High-speed data communication systems
• Telecommunications infrastructure equipment
• Network synchronization devices
• Industrial control systems requiring precise timing

Procurement Notes

Verify the complete part number including suffixes such as CJGLPZ3 against official Epson documentation to ensure correct frequency programming and package configuration. Confirm that the required operating temperature range and supply voltage align with system design specifications. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure that the LVPECL output compatibility matches the receiving circuitry requirements.

Selection Notes

Select this component when a programmable VCXO with LVPECL outputs is required for frequencies up to 800 MHz. Consider the 3.3V supply constraint and the specific current consumption profiles for power budgeting. Evaluate the need for hardware enable/disable controls versus always-on configurations. Verify that the 8-SMD package fits the available PCB footprint and assembly capabilities.

Part Context

This model belongs to Epson's VG7050 series of programmable oscillators. These components are engineered for applications demanding stable clock signals with flexible frequency adjustment. The series typically integrates the necessary tuning elements within a compact surface-mount package, simplifying integration into modern electronic designs compared to discrete crystal solutions.

Replacement Considerations

The VG7050EAN SM18T003-CJGLPZ0 is identified as a direct parametric equivalent with identical disable-mode current specifications. This substitute may be considered for designs requiring minimal current variations. Verify that any replacement maintains the same LVPECL output characteristics and frequency range compatibility.
