The LMK1D1212 clock buffer distributes with minimum skew one of two selectable clock inputs (IN0, IN1) to 12 pairs of differential LVDS clock outputs (OUT0 through OUT11). Similarly, the LMK1D1216 distributes 16 pairs of differential LVDS clock outputs (OUT0 through OUT15). The LMK1D121x family can accept two clock sources into an input multiplexer. The inputs can either be LVDS, LVPECL, LP-HCSL, HCSL, CML, or LVCMOS.
The LMK1D121x is specifically designed for driving 50-Ω transmission lines. When driving inputs in single-ended mode, apply the appropriate bias voltage to the unused negative input pin.
The IN_SEL pin selects the input which is routed to the outputs. If this pin is left open, it disables the outputs (static low). The part supports a fail-safe function. The device further incorporates an input hysteresis which prevents random oscillation of the outputs in the absence of an input signal.
The device operates in 1.8-V or 2.5-V or 3.3-V supply environment and is characterized from –40°C to 105°C (ambient temperature).
