LMK61E0M-SIAT

Overview

The LMK61E0M-SIAT is an ultra-low jitter programmable oscillator manufactured by Texas Instruments. It operates within a frequency range of 50 MHz to 200 MHz and utilizes LVCMOS output format. The device supports a supply voltage of 3.3 V and includes an internal EEPROM for configuration storage. It features enable/disable functionality and is housed in an 8-SMD module package. The component is designed for surface mount installation and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low jitter performance for precision timing applications
• Internal EEPROM enables non-volatile configuration retention
• LVCMOS output interface compatible with standard logic levels
• Integrated enable and disable control function

Applications

• High-speed data communication systems requiring precise clocking
• Test and measurement equipment demanding stable signal generation
• Industrial automation controllers needing reliable timing references
• Telecommunications infrastructure utilizing standard logic interfaces

Procurement Notes

Verify the specific frequency setting required, as this programmable model covers a range rather than a single fixed value. Confirm that the LVCMOS output format aligns with the target circuit's input requirements. Ensure the 8-SMD package dimensions fit the designated PCB footprint. Check for updated design recommendations, as availability status may vary based on production cycles.

Selection Notes

Select this component when a flexible frequency solution between 50 MHz and 200 MHz is necessary without external programming hardware. The internal EEPROM simplifies board design by storing settings permanently. Consider the LVCMOS output swing limits compared to differential outputs if noise immunity is a primary concern. Evaluate power consumption against system thermal constraints given the 3.3 V operation.

Part Context

This part belongs to the LMK61E0 series of ultra-low jitter oscillators from Texas Instruments. Unlike fixed-frequency models, this variant offers programmability through its internal EEPROM. It serves as a versatile clock source for digital systems requiring customizable frequencies within the specified range while maintaining high signal integrity standards typical of the manufacturer's timing products.

Replacement Considerations

Direct substitutes include other LMK61E0 series variants with fixed frequencies or different output formats such as LVPECL. For equivalent LVCMOS programmable options, verify cross-references within the same family ensuring identical package dimensions and electrical characteristics match the original design requirements.
