LMK61E08-SIAT

Overview

The LMK61E08-SIAT is an ultra-low jitter programmable oscillator manufactured by Texas Instruments. It features a QFM-6 surface-mount package with dimensions of 7mm x 5mm x 1.15mm. The device operates within a supply voltage range of 3.135 V to 3.465 V and supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include a maximum supply current of 152 mA, a rise time of 0.2 ns, and a fall time of 0.2 ns. The component integrates internal EEPROM for configuration storage.

Feature Summary

• Integrates internal EEPROM for persistent configuration storage
• Provides ultra-low jitter performance suitable for high-speed data applications
• Supports enable/disable functionality for power management

Applications

• High-speed serial communication interfaces
• Data converter clocking systems
• Telecommunications equipment timing

Procurement Notes

Verify the specific suffix 'SIAT' against official Texas Instruments documentation to confirm the tape-and-reel packaging format and ensure compatibility with automated assembly processes. Confirm that the internal EEPROM configuration matches the target application requirements, as factory defaults may vary. Cross-reference the QFM-6 package outline drawing to validate footprint dimensions for PCB layout integrity.

Selection Notes

Select this component when a fixed-frequency or internally configured ultra-low jitter source is required without external crystal dependencies. The integrated EEPROM simplifies design by removing the need for external configuration memory. Ensure the system power budget accommodates the 152 mA maximum current draw and verify that the 3.3V nominal supply voltage aligns with the available rail.

Part Context

This part belongs to the LMK61 series of silicon oscillators designed for demanding timing applications. Unlike standard crystal oscillators, it offers programmability through internal non-volatile memory. The series targets markets requiring precise clock signals with minimal phase noise, such as optical networking and high-performance computing infrastructure.

Replacement Considerations

LMK61E08-SIAR is a pin-compatible alternative differing only in reel packaging quantity.
