LMK3H0102V18RERT

Overview

The LMK3H0102V18RERT is a bulk acoustic wave (BAW)-based, referenceless clock generator designed for PCIe Gen 1 through Gen 6 compliance. Manufactured by Texas Instruments, it features two single-ended PCIe outputs with a maximum frequency of 400 MHz. The device operates on a supply voltage range of 1.71 V to 3.465 V and draws 125.8 mA of operating current. It exhibits a jitter specification of 150 ps and maintains a duty cycle of up to 60%. Packaged in a TQFN-16 format, the component supports surface-mount installation and functions within an industrial temperature range of -40°C to +85°C.
