Voltage Controlled VCXOs Product Series

Dynamic frequency tuning interfaces developed for real-time phase alignment and clock jitter attenuation. Our VCXOs(Voltage Controlled Crystal Oscillators) portfolio provides high linearity and wide pullable frequency margins, enabling seamless integration into phase-locked loop (PLL) architectures.

Three methods to help you narrow down your choices and find a product range that meets your design requirements.

By Pulling Range & Linearity

Filter by specific tuning parameters required for loop bandwidths. Select standard ±50 ppm pull range for stable clean tracking, or wide options exceeding ±100 ppm paired with strict linearity percentages to maintain control loop stability.

Wide Pull Range (≥100ppm)

High Linearity

By Output Format & Jitter Level

Match your system’s high-speed data requirements. Select CMOS for low-frequency local logic, or choose high-speed differential outputs (LVPECL / LVDS) providing sub-picosecond phase jitter performance for wideband infrastructure.

CMOS Output

Low Jitter (<0.1 ps)

By Sync & Broadcast Application

Secure precision alignment across communication frameworks. Optimize components for instrumentation clock cleanup modules, high-definition broadcast video instrumentation, and network synchronous digital hierarchy nodes.z
