LMK3H0102/LMK3H0102-Q1 Clock Generators

Texas Instruments LMK3H0102/LMK3H0102-Q1 Referenceless Clock Generators are two-output PCIe Gen 1 to Gen 6 compliant reference-less clock generators with Spread Spectrum Clocking (SSC) support. These are based on TI's proprietary Bulk Acoustic Wave (BAW) technology and provide ±25ppm clock outputs without any crystal or external clock reference. These devices can provide two SSC clocks, two non-SSC clocks, or one SSC clock and one non-SSC clock simultaneously. The LMK3H0102/LMK3H0102-Q1 meets the full PCIe compliance from Gen 1 to Gen 6. This compliance includes Common Clock with or without SSC, Separate Reference Independent Spread (SRIS), and Separate Reference No Spread (SRNS). These devices can be easily configured through GPIO pins or an I²C interface. An external DC-DC can be used to power the devices. The LMK3H0102-Q1 devices are AEC-Q100 qualified for automotive applications.
