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.
