Description
General part information
LMKDB1108 Series
The LMKDB devices 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, as well as excellent power supply noise rejection performance.
Both 1.8V and 3.3V supply voltages are supported. For LMKDB1120, 1.8V power supply saves 250mW power compared to 3.3V.
