The 800 MHz maximum frequency sets the upper bound on the clock rate this buffer can pass with acceptable additive jitter. The 2:12 ratio means one input drives twelve LVDS outputs.
The CDCLVD1212RHAT is listed as Active with ROHS3 compliance. No end-of-life notice, no last-time-buy window. For BOM planning, this part is available through independent distribution and is sourced to order against an RFQ.
The closest functional alternative is the CDCLVP1204RGTR, which outputs LVPECL instead of LVDS, runs at 2 GHz, and has a 2:4 fanout ratio. If your design needs LVPECL or fewer outputs, that part is a direct alternative. For LVDS with twelve outputs, the CDCLVD1212 is the part.
No. The LVDS outputs are current-mode drivers that require only a 100-ohm termination resistor at the receiver end. No pull-up resistors are needed on the output lines.
The input accepts LVCMOS, LVDS, and LVPECL levels. For LVDS and LVPECL differential inputs, the common mode range is specified in the datasheet; for LVCMOS single-ended input, the threshold is standard CMOS levels. The part does not require external biasing for standard signal levels.
