Product details

2 GHz fanout buffer with 2:12 ratio

The CDCLVP1212RHAT is a 2:12 fanout buffer from Texas Instruments that distributes a single clock input to twelve LVPECL outputs at up to 2 GHz. It accepts LVCMOS, LVDS, LVPECL, or LVTTL inputs, so the same BOM line can buffer a crystal oscillator, a PLL output, or a backplane clock without a level translator. The supply voltage spans 2.375V to 3.6V, letting it share a 2.5V or 3.3V rail with the rest of the clock tree.

Surface-mount package — the 6x6 mm footprint is manageable on a 4-layer board; the exposed pad needs a via array under it for thermal conduction.

ROHS3 compliant, so it passes EU material restrictions without a waiver.

Frequently asked questions

What is the maximum frequency of CDCLVP1212RHAT?

The buffer is rated for 2 GHz maximum frequency — that is the upper limit for the LVPECL outputs; the input can run at that rate as long as the signal meets the input threshold levels.

What is the equivalent or replacement for CDCLVP1212RHAT?

The closest functional sibling is the CDCLVP1204RGTR, which has the same 2 GHz LVPECL output and multi-protocol inputs but a 2:4 fanout ratio. For designs needing twelve outputs, the CDCLVP1212RHAT is the correct choice; the 1204 is a lower-output-count alternative.
