LMKDB12xx LP-HCSL Clock Multiplexers

Texas Instruments LMKDB12xx LP-HCSL Clock Multiplexers are extremely low-jitter clock muxes for PCIe clocking applications from PCIe Gen 1 to PCIe Gen 7. The series includes the LMKDB1202, LMKDB1204, and LMKDB1208 devices and supports common clock and independent-reference PCIe architectures, with input clocks that use or do not use spread-spectrum clocking.
