800 MHz fanout buffer with divider and mux
The CDCM1802RGTT is a 1:2 fanout buffer that also integrates a divider and a multiplexer — three functions in one 16-VQFN package. The 800 MHz maximum frequency covers most high-speed serial clock distribution needs up to Gigabit Ethernet, FPGA reference clocks, and SERDES reference paths. Input accepts LVCMOS, LVPECL, or LVTTL levels; output can be LVCMOS or LVPECL. The differential input-to-output path (Yes/Yes) means it preserves signal integrity for LVPECL fanout without external level translation.
Supply range and temperature grade
Operates from 3V to 3.6V — a 3.3V nominal rail is the sweet spot. The 16-VFQFN exposed pad (3x3 mm) requires a thermal land on the PCB. The exposed paddle must be soldered to a ground plane for both electrical reference and heat sinking — a common oversight in first prototypes.
Active production — no obsolescence watch
Texas Instruments lists CDCM1802RGTT as Active. ROHS3 compliant. For BOM planning, this part carries no near-term end-of-life risk. Available in Tape & Reel (TR) and Cut Tape (CT) — the CT option is useful for prototype or low-volume builds where you want to avoid the full reel buy.
