LMKDB1 Ultra-Low Jitter Clock Buffers

Texas Instruments LMKDB1 Ultra-Low Jitter Clock Buffers are a family of extremely-low-jitter LP-HCSL buffers and MUX that support PCIe Gen 1 to Gen 6 and are DB2000QL compliant. The devices provide flexible power-up sequence, fail-safe inputs, individual output enable and disable pins, loss of input signal (LOS) detection and automatic output disable features, and excellent power supply noise rejection performance. Both 1.8V and 3.3V supply voltages are supported. For the Texas Instruments LMKDB1120, a 1.8V power supply saves 250mW power compared to 3.3V.

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.
