TG2520SMN 40.0000M-CCGNDMB

Oscillators Overview

The TG2520SMN 40.0000M-CCGNDMB is a Voltage-Controlled Temperature Compensated Crystal Oscillator (VC-TCXO) manufactured by Epson Timing. It operates at a nominal frequency of 40 MHz with a clipped sine wave output format. The device supports a supply voltage range of 1.7V to 3.63V and features a control voltage input of 1.5V. It maintains a frequency stability of 0.5 PPM across an operating temperature range of -40°C to +85°C. The component utilizes a 4-SMD, No Lead package suitable for surface mount applications.

Oscillators Feature Summary

• Integrates voltage-controlled temperature compensation for enhanced frequency stability under varying thermal conditions.
• Provides clipped sine wave output compatible with standard digital logic interfaces.
• Supports wide supply voltage operation from 1.7V to 3.63V for flexible system integration.

Oscillators Applications

• Wireless communication modules requiring stable clock sources
• Portable electronic devices with strict power constraints
• Industrial control systems operating in variable temperature environments

Oscillators Procurement Notes

Verify the specific suffix CCGNDMB against official Epson documentation to confirm the exact control voltage and packaging configuration. Ensure compatibility with the target circuit's supply voltage range and output load requirements. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by regulatory standards.

Oscillators Selection Notes

Select this component when high frequency stability within a narrow ppm tolerance is required alongside voltage tuning capabilities. Consider the 4-SMD package size for PCB layout constraints. Evaluate the 0.5 PPM stability specification against system jitter requirements. Ensure the operating temperature range covers the intended environmental conditions.

Oscillators Part Context

This oscillator belongs to the TG2520SMN series, designed for compact surface-mount applications. The series offers various frequency options and stability grades. The specific model integrates VC-TCXO technology to compensate for temperature-induced frequency drift, providing superior performance compared to standard TCXOs in dynamic thermal environments.

Oscillators Replacement Considerations

Direct substitutes include other Epson TG2520SMN variants with matching 40 MHz frequency and 0.5 PPM stability, such as TG2520SMN 40.0000M-ECGNNM0, provided pinout and electrical specifications align. Verify that alternative models support the same 1.7V–3.63V supply range and clipped sine wave output.
