1.4 Device Information

The LMKDB1108 is a high performance LP-HCSL buffer that supports PCIe Gen 1 to Gen 6 and is DB2000QL compliant. LMKDB1108 has extremely low additive jitter, fail safe inputs, flexible power-up sequence, individual output enable pins, loss of input signal detection, and 3-wire or 4-wire SBI and SMBUs interface. The EVM has integrated LDOs for excellent power supply noise suppression with operating supply voltage of 3.3-V.
