LMK3H0102V33RERR

Overview

The LMK3H0102V33RERR is a bulk acoustic wave (BAW)-based PCIe Gen clock generator manufactured by Texas Instruments. It operates within a supply voltage range of 1.71 V to 3.465 V and delivers a maximum output frequency of 400 MHz. The device features two single-ended outputs with a maximum duty cycle of 53% and exhibits a jitter specification of 20 ps. Designed for surface-mount installation, it is housed in a TQFN-16 package. The component supports spread-spectrum clocking (SSC) functionality and functions as a reference-less clock generator compatible with PCIe generations 1 through 6.

Feature Summary

• Integrates bulk acoustic wave (BAW) technology for high-performance clock generation without requiring an external reference oscillator.
• Supports spread-spectrum clocking (SSC) capabilities to assist in electromagnetic interference reduction.
• Provides dual single-ended clock outputs optimized for compliance with PCIe Gen 1 through Gen 6 standards.

Applications

• PCIe Gen 1 through Gen 6 compliant system designs
• High-speed data transmission interfaces requiring low-jitter clock signals
• Server and storage infrastructure clock distribution

Procurement Notes

Verify the specific suffix 'V33' against the official Texas Instruments datasheet to confirm pinout compatibility and electrical characteristics. Ensure the ordering part number matches the required package type and temperature rating. Confirm RoHS compliance status and moisture sensitivity level prior to procurement to ensure proper handling and storage conditions are met during assembly.

Selection Notes

Select this component when designing systems requiring a reference-less clock solution for PCIe applications up to Generation 6. The integrated BAW resonator eliminates the need for external crystal oscillators, reducing board space. Consider the 20 ps jitter specification and 400 MHz maximum frequency to ensure they meet the timing requirements of the target interface. Verify that the TQFN-16 package fits the available footprint constraints.

Part Context

This device belongs to the LMK3H0102 family of clock generators from Texas Instruments. The family includes variants such as the LMK3H0102A002RERR and automotive-grade LMK3H0102TV3RGTRQ1. These components share similar core functionalities but differ in output configurations, packaging, and qualification standards. The LMK3H0102 series is designed to replace traditional crystal-based solutions in high-speed serial link applications.
