1.4 Device Information

The LMKDB1120 is a high performance LP-HCSL buffer that supports PCIe Gen 1 to Gen 6 and is DB2000QL compliant. LMKDB1120 has extremely low additive jitter, fail safe inputs, flexible power-up sequence, individual output enable pins (OE#), loss of input signal detection (LOS), 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 3.3V.
