The CDCLVP1204RGTR is a Texas Instruments clock fanout buffer and multiplexer that selects between two inputs and distributes the chosen clock to four outputs. It operates to a maximum frequency of 2 GHz with a 450 ps propagation delay and a 50 percent output duty cycle, accepting LVTTL input levels. The CDCLVP1204RGTR runs from a 2.375 V to 3.6 V supply and draws about 45 mA operating current. It is supplied in a 16-pin VQFN measuring 3 mm x 3 mm x 1 mm with gold contact plating, is lead free and RoHS compliant, and ships on tape and reel in 3, 000-piece quantities.

Clock distribution devices take one reference and replicate it to several destinations with matched delay, which is essential once a single oscillator output can no longer drive multiple loads without degrading edge rate or skew. The CDCLVP1204RGTR adds a 2:1 input mux ahead of the fanout, so a board can switch between a primary and redundant or test clock source without extra external logic. Support to 2 GHz places it in high-speed serial and RF-adjacent designs such as Ser Des reference clocking, data converter sampling clocks, backplane and line-card timing, and test equipment. Typical buyers are telecom and networking equipment designers, wireless infrastructure teams, data center hardware groups and test and measurement manufacturers.
