Overview
The LMX1204RHAR is a low-noise, high-frequency RF buffer, multiplier, and divider manufactured by Texas Instruments. It operates within an input frequency range of 300 MHz to 12.8 GHz. The device supports JESD204B/C SYSREF for phase synchronization. It functions on a supply voltage between 2.4 V and 2.6 V. The component is housed in a VQFN-40 package and is rated for operation from -40°C to +85°C.
Feature Summary
- Provides RF buffering, multiplication, and division capabilities up to 12.8 GHz
- Supports JESD204B/C SYSREF signals for precise phase synchronization
- Designed with ultralow jitter characteristics for high-precision applications
Applications
- Clocking high-precision, high-frequency data converters
- Radar systems requiring stable high-frequency references
- Telecommunications infrastructure utilizing JESD204 interfaces
Procurement Notes
Verify the specific ordering suffix RHAR against your bill of materials to ensure correct packaging configuration. Confirm that the VQFN-40 footprint matches your PCB layout requirements. Ensure supply voltage rails are strictly maintained within the 2.4 V to 2.6 V operational window during integration testing.
Selection Notes
Select this component when system design requires a single device to perform buffering, multiplication, and division functions simultaneously. It is suitable for designs needing JESD204B/C SYSREF support without external synchronization circuitry. Consider its ultralow jitter performance if driving sensitive analog-to-digital converters at frequencies up to 12.8 GHz.
Part Context
This part belongs to the LMX1204 family of RF PLLs and synthesizers. It is specifically engineered as a low-noise, high-frequency solution. The device integrates multiple RF functions into one compact package, reducing board space compared to discrete solutions. It is distinct from lower-frequency variants in the same product line.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing clock trees before considering alternative devices.
