LMK3H0102A001RERT

Overview

The LMK3H0102A001RERT is a PCIe Gen clock generator IC from Texas Instruments, utilizing Bulk Acoustic Wave (BAW) technology. It features one output with a maximum frequency of 400 MHz and operates on a single-ended LP-HCSL output type. The device supports spread spectrum clocking (SSC) with a maximum duty cycle of 53%. It functions within a supply voltage range of 1.71 V to 3.465 V, drawing approximately 97.8 mA of operating current. Jitter performance is specified at 20 ps. The component is housed in a 16-TQFN package measuring 3x3 mm and is designed for surface mount installation.

Feature Summary

• Integrates BAW-based filtering for low-jitter clock generation compliant with PCIe specifications
• Supports Spread Spectrum Clocking (SSC) functionality to reduce EMI emissions
• Provides single-ended LP-HCSL output signaling for direct interface compatibility

Applications

• PCI Express (PCIe) system clock distribution
• High-speed serial link reference clock generation
• Server and storage infrastructure timing solutions

Procurement Notes

Verify the specific suffix 'RERT' against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Confirm that the part status is active, as some variants in this series may be obsolete or restricted. Ensure compliance with RoHS directives and moisture sensitivity levels prior to procurement. Cross-reference the ordering number with the latest datasheet revision to avoid discrepancies in electrical characteristics or pinout definitions.

Selection Notes

Select this component when a single-output PCIe reference clock with integrated BAW filtering is required. It is suitable for designs needing SSC capability to meet EMI standards without external filters. Consider the 16-TQFN package size for board space constraints. Verify that the LP-HCSL output level matches the downstream receiver requirements. Evaluate the 400 MHz maximum frequency limit against the target bus speed requirements.

Part Context

This part belongs to the LMK3H0102 family of reference-less clock generators designed specifically for high-speed interfaces like PCIe. The family utilizes proprietary BAW resonators to achieve superior jitter performance compared to traditional PLL-only solutions. Variants differ by output count, package style, and specific configuration options, all sharing the core BAW-based architecture for compact, low-noise clock generation.

Replacement Considerations

Check for LMK3H0102A001RERR if a different reel specification is needed. Consult the manufacturer for alternative packages if the 16-TQFN form factor is unsuitable. Verify availability of newer revisions if the current part is marked obsolete.
