LMX1214RHAR

Overview

The LMX1214RHAR is a low-noise, high-frequency buffer and divider manufactured by Texas Instruments. It operates within a frequency range of 300MHz to 18GHz for clock buffering applications. The device supports divider output frequencies up to 8GHz. It features an ultra-low noise floor and very low skew clock distribution capabilities. The component provides four high-frequency output clocks along with one low-frequency auxiliary clock output. It functions in both buffer mode and divider mode for high-frequency signals. The device is housed in a 40-pin VQFN package measuring 6mm x 6mm.

Procurement Notes

Verify the specific ordering suffix RHAR against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure the requested part matches the exact electrical characteristics and pinout defined in the current datasheet revision. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and supply chain integrity before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring high-frequency clock distribution with minimal phase noise. Consider the 300MHz to 18GHz operational range and the availability of four high-frequency outputs plus one auxiliary output. Evaluate the need for divider functionality supporting up to 8GHz outputs. Confirm that the 40-pin VQFN package dimensions fit the target PCB layout constraints and thermal requirements.

Part Context

The LMX1214 belongs to the LMX family of RF buffer and divider components designed for high-performance signal integrity. It addresses the need for precise clock distribution in complex electronic systems. The RHAR variant specifies the particular packaging and reel configuration offered by Texas Instruments. This component serves as a critical interface between signal sources and downstream processing stages requiring clean, low-skew timing references.

Replacement Considerations

Consult official Texas Instruments substitution guides for verified alternative part numbers. Do not assume cross-compatibility with other LMX series devices without verifying pinout and electrical parameter alignment. Review updated datasheets for any functional changes in successor components.
