CDCLVD2106RHAR

Overview

The CDCLVD2106RHAR is a low jitter, dual 1:6 universal-to-LVDS buffer manufactured by Texas Instruments. It operates on a single 2.5V supply (2.375V to 2.625V) and supports input frequencies up to 800 MHz. The device accepts LVCMOS, LVDS, or LVPECL inputs and converts them to LVDS outputs. It features an additive RMS jitter of typically 171 fs. Packaged in a 40-VQFN (6x6 mm) with an exposed pad, it is designed for surface mount assembly within an operating temperature range of -40°C to 85°C.

Feature Summary

• Dual 1:6 fanout buffer architecture providing 12 LVDS outputs
• Universal input compatibility supporting LVCMOS, LVDS, and LVPECL logic levels
• Low additive RMS jitter specification of 171 fs typical
• Operates at maximum input/output frequencies of 800 MHz

Applications

• Clock distribution networks requiring low jitter performance
• System synchronization in high-speed digital interfaces
• Signal buffering for LVDS-based communication links

Procurement Notes

Verify the specific ordering suffix RHAR corresponds to the Tape & Reel packaging configuration. Confirm that the 40-VQFN package dimensions match the design footprint requirements. Ensure the voltage supply range aligns with the system's 2.5V rail tolerance.

Selection Notes

Select this component when a dual-channel buffer is needed to drive multiple LVDS loads from various input standards. The 800 MHz frequency limit suits moderate-high speed applications. Consider the 40-pin VQFN package for space-constrained PCB layouts requiring thermal exposure pads.

Part Context

This part belongs to the CDCLVD series of clock buffers. It serves as a signal conditioning component, translating standard logic inputs into differential LVDS signals for noise-immune transmission. The dual-structure allows independent processing of two input sources.

Replacement Considerations

Check datasheets for other CDCLVD series parts with similar 1:6 ratios and LVDS outputs. Verify pinout compatibility and electrical specifications such as jitter and supply voltage before substitution.
