LMX1205RHAR

Overview

The LMX1205RHAR is a low-noise, high-frequency buffer, multiplier, and divider manufactured by Texas Instruments. It operates within an output frequency range of 300 MHz to 12.8 GHz. The device supports JESD204B/C standards and features programmable clock delays with noiseless adjustable input delay up to 60 ps and 1.1 ps resolution. It functions on a supply voltage between 2.4 V and 2.6 V. The component is housed in a 40-pin VQFN package (RHA) measuring 6x6 mm. It is rated for operation from -40°C to +85°C.

Feature Summary

• Supports JESD204B/C interface standards for high-speed data converter synchronization
• Provides noiseless programmable clock delay adjustment with fine resolution
• Functions as a low-noise buffer, multiplier, and divider for RF signals

Applications

• JESD204B/C compliant digital-to-analog and analog-to-digital converter interfaces
• High-frequency radar systems requiring precise clock distribution
• Test and measurement equipment needing low-phase noise signal generation

Procurement Notes

Verify the specific ordering suffix RHA confirms the 40-VQFN package type and tape-and-reel packaging configuration. Ensure the procurement request explicitly states the required operating temperature range and supply voltage specifications to match the datasheet parameters. Confirm RoHS compliance status through official manufacturer documentation prior to finalizing purchase orders.

Selection Notes

Select this component when designing systems requiring JESD204B/C synchronization with precise timing alignment. The integrated programmable delay functionality eliminates external delay lines. Consider the 12.8 GHz maximum output frequency limit and the 2.4V to 2.6V power supply requirements during circuit design. Evaluate thermal performance within the specified -40°C to +85°C operational range.

Part Context

The LMX1205RHAR belongs to the LMX1205 family of low-noise, high-frequency clock generators. It is designed specifically for applications demanding strict jitter performance and flexible clock routing. The RHAR variant denotes the surface-mount package configuration suitable for automated assembly processes in modern electronic manufacturing.

Replacement Considerations

Consult Texas Instruments official substitution guides for direct replacements. Verify pin compatibility and electrical parameter equivalence before integrating alternative components into existing designs.
