What this clock buffer does on your board
The Texas Instruments CDCLVP1212RHAR is a 2:12 fanout buffer with an integrated 2:1 input multiplexer, designed to distribute one of two selectable clock sources to up to 12 LVPECL loads. It accepts LVCMOS, LVDS, LVPECL, or LVTTL inputs and outputs LVPECL, covering the common high-speed signaling standards used in telecom backplanes, data-center switches, and FPGA reference-clock trees. The part operates from a 2.375 V to 3.6 V supply and is rated for the industrial temperature range of -40°C to 85°C, making it suitable for outdoor base stations and factory-floor equipment where temperature swings are routine.
2 GHz bandwidth and 2:12 fanout — what they mean for your clock tree
The 2 GHz maximum frequency covers high-speed serial links. The 2:12 ratio means a single device replaces multiple lower-fanout buffers, saving board space and reducing part count. The differential input and output path preserves signal integrity over long traces.
Lifecycle and sourcing
The CDCLVP1212RHAR is listed as Active and ROHS3 compliant. There is no end-of-life notice or last-time-buy window to track. For current pricing and availability, submit an RFQ through the independent distribution channel — availability and pricing are confirmed at quote time. No immediate obsolescence risk; this part is still a valid choice for new production builds.
