Product details

1:4 LVDS fanout at 800 MHz — two independent buffers

The CDCLVD2104RHDR is a dual 1:4 fanout buffer from Texas Instruments, each buffer distributing one input to four LVDS outputs at up to 800 MHz. It accepts LVCMOS, LVDS, or LVPECL inputs, which means you can feed it from a crystal oscillator, a PLL, or a serializer without level-shifting the signal path first. The differential input-to-output path is fully differential, preserving signal integrity across the fanout tree. This matters when you are splitting a high-speed clock to multiple ADCs, FPGAs, or SerDes transceivers and cannot afford added jitter from single-ended routing.

Supply rail and thermal — 2.5 V nominal, exposed-pad grounding

The supply range is 2.375 V to 2.625 V, so it runs cleanly off a 2.5 V rail. No AEC-Q100 rating is listed, so it is not qualified for automotive under-hood use.

Frequently asked questions

Can CDCLVD2104RHDR accept LVPECL input?

Yes, the input stage accepts LVCMOS, LVDS, and LVPECL levels. No external level translation is needed when driving it from a standard LVPECL source.

What is the closest functional alternative to CDCLVD2104RHDR?

The CDCLVP1204RGTR is a 2:4 fanout buffer with LVPECL outputs, also from TI. It accepts the same input types plus LVTTL, runs at 2 GHz max, and comes in a similar 28-VQFN package. The key difference is output logic family — LVDS vs LVPECL — so the choice depends on your downstream receiver requirements.
