Product details

800 MHz fanout buffer with wide input flexibility

Its input stage accepts CML, HSTL, LVDS, LVPECL, LVTTL, SSTL-2, and VML, so this single part can sit behind most high-speed serial interface standards without external level shifters. Outputs are LVCMOS or LVPECL, and the signal path is fully differential, which preserves edge integrity in noisy backplanes or long PCB traces.

1:3 ratio vs 2:4 peer

Compared to the CDCLVP1204RGTR, which offers a 2:4 input:output ratio and 2 GHz max frequency, the CDCM1804RGET runs a 1:3 ratio at 800 MHz. The CDCLVP1204 also accepts LVCMOS, LVDS, LVPECL, and LVTTL, but omits CML, HSTL, SSTL-2, and VML. If your clock source is CML or SSTL-2, the CDCM1804RGET is the direct fit; for higher fan-out or 2 GHz rates, the CDCLVP1204RGTR is the alternative.

Frequently asked questions

Is CDCM1804RGET equivalent to CDCM1804RGEE?

The suffix difference (RGET vs RGEE) typically indicates packaging or tape/reel variant. The RGEE variant is not in our evidence; confirm the exact order code against your BOM to avoid footprint or supply-voltage mismatches.

What is the CDCM1804RGET's listed type?

It is a Fanout Buffer (Distribution), Divider, Multiplexer. This means it can buffer a clock signal to three outputs, divide the frequency, or select between multiple clock sources — all in one 24-QFN package.
