LMK3H0102A014RERT

Overview

The LMK3H0102A014RERT is a programmable Bulk Acoustic Wave (BAW) clock generator from Texas Instruments, designed for PCIe Gen 1 to Gen 7 compliance. It features two single-ended outputs with a maximum frequency of 400 MHz and supports Spread Spectrum Clocking (SSC). The device operates on a supply voltage ranging from 1.8 V to 3.3 V, drawing approximately 125.8 mA. Packaged in a TQFN-16 form factor, it exhibits a jitter specification of 150 ps and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Programmable BAW-based architecture supporting PCIe Gen 1 through Gen 7 standards
• Two single-ended output channels with a maximum operating frequency of 400 MHz
• Integrated Spread Spectrum Clocking (SSC) capability for EMI reduction
• TQFN-16 surface-mount package suitable for compact board designs

Applications

• PCIe endpoint and root complex clock generation
• High-speed serial interface timing solutions
• Industrial and automotive electronic systems requiring low jitter

Procurement Notes

Verify the specific suffix 'RERT' against official Texas Instruments documentation, as public listings predominantly reference the 'RERR' variant. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure compatibility with the LMK3H0102EVM evaluation module for initial configuration testing.

Selection Notes

Select this component when dual single-ended outputs are required for PCIe applications. Compare the 150 ps jitter performance against other variants like the A01ERERR if lower jitter is critical. Verify that the 1.8 V to 3.3 V supply range aligns with the system power rails and that the TQFN-16 footprint fits the PCB layout constraints.

Part Context

This part belongs to the LMK3H0102 family of BAW clock generators. It shares the core technology with variants such as LMK3H0102A01DRERR but differs in output type and configuration. The family is engineered to meet stringent timing requirements for next-generation high-speed interconnects.

Replacement Considerations

Direct substitutes include LMK3H0102A01ERERR and LMK3H0102A002RERR. Note that these alternatives may offer different jitter specifications or output configurations. Validate pin-to-pin compatibility and electrical parameters before swapping.
