VG7050ECN-SM20T007-CJGLPF0

Overview

The VG7050ECN-SM20T007-CJGLPF0 is a programmable voltage-controlled crystal oscillator (VCXO) manufactured by Epson. It operates within a frequency range of 50 MHz to 800 MHz, utilizing low jitter fractional-N PLL technology with 2 ppb resolution. The device features LVPECL output and supports 2.5 V or 3.3 V power supplies, consuming less than 90 mA. It integrates phase noise below 0.3 ps rms (12 kHz to 20 MHz) and includes four user-programmable preset frequencies selectable via two pins. Configuration is managed through an I2C bus interface with a 7-bit address.

Feature Summary

• Integrates low jitter fractional-N PLL technology for precise frequency tuning
