SX7V19.440B10080F20TNNS

Oscillators Overview

The SX7V19.440B10080F20TNNS is a Voltage Controlled Crystal Oscillator (VCXO) manufactured by Shenzhen SCTF Electronics. It operates at a nominal frequency of 19.44 MHz and utilizes CMOS output logic. The device is designed for operation with a supply voltage of 3.3 V and includes an enable/disable control function. It is housed in a compact 6-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Voltage controlled crystal oscillator architecture providing tunable frequency output
• CMOS output interface compatible with standard digital logic levels
• Integrated enable and disable control pin for power management

Oscillators Applications

• Clock generation in communication equipment
• Timing reference sources for data transmission systems
• Frequency synthesis circuits in RF modules

Oscillators Procurement Notes

Verify the manufacturer designation Shenzhen SCTF Electronics against the component marking to ensure authenticity. Confirm the 6-SMD No Lead package dimensions match the design footprint. Validate that the 3.3 V supply requirement aligns with the system power rails. Ensure the enable/disable functionality is supported by the host controller logic.

Oscillators Selection Notes

Select this component when a stable 19.44 MHz reference with voltage tuning capability is required. The CMOS output simplifies interfacing with digital processors compared to LVDS or HCSL options. The 3.3 V operating voltage suits modern low-power embedded designs. The enable feature allows for dynamic power saving in battery-operated devices.

Oscillators Part Context

This VCXO belongs to the family of precision timing components used for generating stable clock signals. Unlike fixed-frequency oscillators, VCXOs allow slight frequency adjustments via a control voltage, making them essential for applications requiring phase alignment or jitter cleaning in high-speed serial links.
