CDCLVP2104RHDR

Overview

The CDCLVP2104RHDR is a high-performance, low-additive-jitter clock buffer manufactured by Texas Instruments. It features a dual 1:4 differential buffering architecture, providing eight LVPECL outputs from two independent inputs. The device supports input signals including LVCMOS, LVDS, LVPECL, and LVTTL. It operates at a maximum frequency of 2 GHz with a supply voltage range of 2.375 V to 3.6 V. Packaged in a 28-VQFN (5x5 mm) case with an exposed pad, it is designed for surface mount installation and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual 1:4 differential buffer configuration supporting two inputs and eight LVPECL outputs
• Maximum operating frequency of 2 GHz with low additive jitter performance
• Universal input compatibility accepting LVCMOS, LVDS, LVPECL, and LVTTL signals
• Operates on a single 2.375 V to 3.6 V power supply

Applications

• High-speed communication systems requiring precise clock distribution
• Network routers and switches utilizing LVPECL interfaces
• Test and measurement equipment demanding low skew timing
• Servers and storage systems needing multi-channel clock buffering

Procurement Notes

Verify the specific suffix RHDR corresponds to the Tape & Reel packaging format when ordering. Confirm that the 28-VQFN package dimensions and exposed pad thermal requirements align with the target PCB layout. Ensure the design accommodates the specified 2.375 V to 3.6 V supply voltage range for proper operation.

Selection Notes

Select this component when a dual-input to eight-output LVPECL fanout buffer is required for frequencies up to 2 GHz. It is suitable for designs needing universal input support across LVCMOS, LVDS, LVPECL, and LVTTL standards. Consider the 28-pin VQFN package constraints and thermal dissipation needs associated with the exposed pad for high-frequency applications.

Part Context

This part belongs to the CDCLVP series of clock buffers and drivers from Texas Instruments. It serves as a fanout buffer specifically optimized for distributing clock signals in high-speed digital environments. The device complements other TI interface solutions by providing robust signal integrity and low jitter characteristics essential for modern data communication protocols.

Replacement Considerations

Check for direct pin-compatible alternatives within the CDCLVP family or similar LVPECL buffer series from Texas Instruments. Verify that any substitute maintains the 2:8 ratio, 2 GHz frequency capability, and compatible input/output voltage levels before integration.
