Product details

2 GHz fanout buffer for high-speed clock distribution

The Texas Instruments CDCLVP2104RHDT is a 2:8 fanout buffer that accepts LVCMOS, LVDS, LVPECL, or LVTTL inputs and delivers eight LVPECL outputs at up to 2 GHz. It operates from a single 2.375 V to 3.6 V supply.

28-VQFN package — rework and layout notes

The 28-VFQFN with exposed pad (5x5 mm) is the same footprint used across the CDCLVP family. The exposed pad must be soldered to a ground plane — a via array under the pad is the standard practice.

Lifecycle and sourcing posture

The CDCLVP2104RHDT carries an Active lifecycle status from Texas Instruments. The part is ROHS3 compliant. For current builds, there is no near-term obsolescence risk.

Frequently asked questions

Can CDCLVP2104RHDT work with a 3.3V supply?

Yes, the supply range is 2.375 V to 3.6 V, so a 3.3 V rail is well within the operating window. The same part also works from a 2.5 V rail without a separate regulator.

What are the alternatives to CDCLVP2104RHDT?

The CDCLVP1204RGTR is a 2:4 fanout buffer with the same input types, LVPECL outputs, and 2 GHz frequency ceiling. It saves board area and cost when only four outputs are needed. Both parts share the same supply range and temperature grade.

Can CDCLVP2104RHDT be used as a 1:8 fanout buffer?

The part has a 2:8 ratio, meaning two inputs and eight outputs. If only one input is used, the second input can be left unconnected or tied to a static level — the datasheet covers the unused input termination. It functions as a 1:8 buffer with one active input.
