LMK3H0102A014RERR

Overview

The LMK3H0102A014RERR is a programmable Bulk Acoustic Wave (BAW) clock generator manufactured by Texas Instruments. It features two outputs with a maximum frequency of 400 MHz and supports LP-HCSL, LVCMOS, and LVDS output types. The device operates within a supply voltage range of 1.8 V to 3.3 V and draws 125.8 mA. Packaged in a TQFN-16 format, it functions between -40°C and +85°C with a jitter specification of 150 ps.

Feature Summary

• Programmable BAW-based architecture for PCIe Gen applications
• Dual output configuration supporting LP-HCSL, LVCMOS, and LVDS
• Maximum output frequency of 400 MHz
• Jitter performance of 150 ps

Applications

• PCIe Gen clock generation
• Automotive driver assistance systems
• High-reliability timing solutions

Procurement Notes

Verify the specific suffix '4' in the part number LMK3H0102A014RERR against official datasheets, as it distinguishes this variant from other LMK3H0102 models like the A01DRERR. Confirm humidity sensitivity handling requirements due to the Yes designation. Ensure the development kit LMK3H0102EVM is available for configuration validation prior to production integration.

Selection Notes

Select this component when a programmable BAW solution is required for high-frequency clocking up to 400 MHz. Compare the 150 ps jitter against the 25 ps jitter of the LMK3H0102A01DRERR if lower phase noise is critical. Verify that the 1.8 V to 3.3 V operating voltage aligns with the system power rails and that the TQFN-16 package fits the PCB layout constraints.

Part Context

This device belongs to the LMK3H0102 family of BAW clock generators designed to replace traditional quartz oscillators. It offers improved reliability compared to quartz-based solutions, with a specified FIT value of 0.3. The family includes variants such as the LMK3C0105 for reference-less generation and evaluation tools like the LMK3H0102EVM for development support.

Replacement Considerations

The LMK3H0102A01DRERR is a similar dual-output BAW clock generator but features different electrical characteristics, including a wider voltage range (1.71 V to 3.465 V), lower jitter (25 ps), and a different duty cycle. Substitution requires verification of pin compatibility and performance parameter alignment.
