Description
AI
The CDCLVD1208 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 CDCLVD1208 can accept two clock sources into an input multiplexer. The inputs can either be LVDS, LVPECL, or LVCMOS.
The CDCLVD1208 is specifically designed for driving 50-Ω transmission lines. In case of driving the inputs in single-ended mode, the appropriate bias voltage, VAC_REF, must be applied 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). The part supports a fail-safe function. The device incorporates an input hysteresis which prevents random oscillation of the outputs in the absence of an input signal.
The device operates in 2.5-V supply environment and is characterized from –40°C to 85°C (ambient temperature). The CDCLVD1208 is packaged in small, 28-pin, 5-mm × 5-mm VQFN package.
