SNAU309 October 2025 LMK3H2108
The LMK3H2108 is a high-performance PCIe compliant clock generator that supports PCIe Gen 1 to Gen 7. The LMK3H2108 can generate any frequency between 2.5MHz and 400MHz differential or any frequency up to 200MHz single-ended. The LMK3H2108 has fail-safe inputs, a flexible power-up sequence, individually controllable outputs through headers or USB2ANY control, and an I2C interface for configuration. The EVM has integrated LDOs for excellent power supply noise suppression with an operating supply voltage of 1.8V, 2.5V, or 3.3V.
