The LMK1D210xL is a low noise dual clock buffer which distributes one input to a maximum of 2 (LMK1D2102L), 4 (LMK1D2104L), 6 (LMK1D2106L) or 8 (LMK1D2108L) LVDS outputs. The inputs can either be LVDS, LVPECL, HCSL, CML, or LVCMOS.

The LMK1D210xL is specifically designed for driving 50Ω transmission lines. When driving inputs in single-ended mode, apply the appropriate bias voltage to the unused negative input pin (see Figure 8-8).

LMK1D210xL buffer offers two output common mode operation (0.7V and 1.2V) for different operating supply. The device provides flexibility in design for DC-coupled mode applications.

AMP_SELA / AMP_SELB control pin can be used to select different output amplitude LVDS (350mV) or boosted LVDS (500mV). In addition to amplitude selection, outputs can be disabled using the same pin.

The part also supports Fail-Safe Input function for clock and digital input pins. The device further incorporates an input hysteresis which prevents random oscillation of the outputs in the absence of an input signal.
