CDCLVP111RHBR

Overview

The CDCLVP111RHBR is a low-voltage 1:10 LVPECL clock driver manufactured by Texas Instruments. It distributes one differential clock input pair to ten differential LVPECL output pairs with minimum skew, supporting frequencies up to 3.5 GHz. The device accepts CML, LVDS, LVPECL, and SSTL inputs and operates on a supply voltage range of 2.375 V to 3.8 V. It features selectable clock inputs via CLK_SEL, additive RMS jitter of typically 40 fs at 3.5 GHz, and propagation delay less than 350 ps. Packaged in a 32-VQFN (5x5 mm) exposed pad case, it is designed for driving 50-Ω transmission lines in high-performance clock distribution applications.

• Low Additive Jitter (Typical 40 fs at 3.5 GHz)
• Operating Temperature Range -40°C to 85°C

Applications

• High Performance Clock Distribution Systems
• Driving 50-Ohm Transmission Lines
• Telecommunications Infrastructure

Procurement Notes

Verify the package type matches the required 32-VQFN (5x5 mm) footprint. Confirm that the supply voltage requirements align with the 2.375 V to 3.8 V operating range. Ensure the design supports LVPECL output levels and differential signaling standards. Check for RoHS compliance if environmental regulations apply to the specific manufacturing batch.

Selection Notes

Select this component when a single differential clock source needs to drive ten LVPECL loads with minimal skew. It is suitable for systems requiring compatibility with multiple input standards including CML, LVDS, and SSTL. Consider the 32-VQFN package for space-constrained surface mount designs. Verify that the maximum frequency requirement does not exceed 3.5 GHz.

Part Context

This part belongs to the CDCLVP111 series of low-voltage clock drivers. It is functionally similar to other 1:10 LVPECL buffers but offers specific input multiplexing capabilities. The RHBR suffix indicates the tape and reel packaging format. It serves as a fanout buffer for distributing clock signals in high-speed digital systems.

Replacement Considerations

Pin-to-pin compatible alternatives include MC100LVEP111, ES6111, LVEP111, and PTN1111. Verify electrical parameters such as supply voltage and output current before substitution.
