M61012SFCN 20.000000

Overview

The M61012SFCN 20.000000 is a precision TCXO/TCVCXO clock oscillator manufactured by MtronPTI, housed in a compact 5x7 mm leadless ceramic package. It operates at a nominal frequency of 20 MHz and supports multiple supply voltages including 3.3 V, with options for 1.8 V and 2.5 V configurations. The device features HCMOS output levels and is designed for high-performance applications requiring superior jitter performance comparable to SAW-based oscillators. It includes an enable/disable function to reduce static power consumption during sleep modes, making it suitable for telecommunications, wireless base stations, and avionic systems.

Feature Summary

• Compact 5x7 mm leadless ceramic surface-mount package design
• HCMOS output with enable/disable control for power management
• Superior jitter performance comparable to SAW-based oscillators
• Supports multiple voltage inputs including 3.3V, 2.5V, and 1.8V

Applications

• Telecommunications equipment such as SONET/SDH and DWDM systems
• Wireless base stations and WLAN infrastructure
• Avionic flight controls and military communications

Procurement Notes

Verify the specific voltage variant (1.8V, 2.5V, or 3.3V) required for your application, as the part number suffix may indicate different electrical characteristics. Confirm that the HCMOS output type aligns with your system's logic requirements. Ensure the 5x7 mm package dimensions fit within your PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when high stability and low jitter are critical for timing-sensitive applications. The integrated enable pin allows for dynamic power management, which is beneficial for battery-operated or energy-efficient designs. Consider the operating temperature range of -40°C to +85°C to ensure reliability in harsh environments. The CMOS output simplifies interface design compared to differential outputs like LVPECL or LVDS.

Part Context

This model belongs to the M610x series of precision TCXOs from MtronPTI. The series is characterized by its small form factor and robust ceramic packaging, which contributes to long-term stability. These oscillators are engineered to replace larger traditional crystal units while maintaining or improving frequency accuracy and phase noise specifications across various industrial and commercial sectors.

Replacement Considerations

Direct substitutes include other MtronPTI models from the same 5x7 mm family, such as the M61011SFCN or M61016STCN, provided they match the 20 MHz frequency and HCMOS output requirements. Verify that any replacement maintains the same supply voltage and enable functionality to ensure circuit compatibility without redesign.
