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.
No end-of-life notice, no last-time-buy window.
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.
