The LMK1D1208P clock buffer distributes one of two selectable clock inputs (IN0 and IN1) to 8 pairs of differential LVDS clock outputs (OUT0 through OUT7) with minimum skew for clock distribution. The inputs can be either LVDS, LVPECL, LVCMOS, HCSL, or CML.
The LMK1D1208P 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. The part supports a fail-safe
input function. The device further incorporates an input hysteresis which prevents
random oscillation of the outputs in the absence of an input signal.
Each LVDS differential output is enabled by
setting the corresponding OEx pin to a logic high 1. If this pin is set to a logic
low 0, the output is disabled in a Hi-Z state resulting in reduced power
consumption.
The device operates in a 1.8-V, 2.5-V, or 3.3-V
supply environment and is characterized from –40°C
to 105°C (ambient temperature).
