VG7050ECN-SM20T003-CJGLPZ0

Overview

The VG7050ECN-SM20T003-CJGLPZ0 is a programmable voltage-controlled crystal oscillator (VCXO) manufactured by Epson. It operates on a single 2.5V or 3.3V supply and features LVPECL output. The device covers a frequency range of 50 MHz to 800 MHz with a tuning resolution of 2 ppb. Key electrical parameters include a maximum phase jitter of 0.3 ps rms (measured between 12 kHz and 20 MHz) and a current consumption of less than 90 mA. The unit supports a 50 ppm stability over the operating temperature range of -40°C to +85°C. It utilizes a base fundamental crystal for reliable operation, including low-temperature startup.

Feature Summary

• Integrates low-jitter PLL technology for precise signal generation
• Supports user-specified four start-up frequencies selectable via two pins
• Allows frequency reprogramming through an I2C bus interface
• Utilizes base fundamental crystal for enhanced reliability

Applications

• SONET/SDH systems
• OTN networks
• GbE applications
• Fibre Channel interfaces

Procurement Notes

Verify component authenticity using official Epson documentation and part number markings. Confirm that the specific suffix matches the required pinout and packaging specifications. Ensure compatibility with system voltage levels and I2C address configurations before integration. Check for any end-of-life notices as availability may be limited.

Selection Notes

Select this component when low phase jitter and programmable frequency control are critical requirements. It is suitable for designs requiring LVPECL outputs and operation within industrial temperature ranges. Consider the I2C interface capability for dynamic frequency adjustments in complex timing architectures.
