CDCLVD2102RGTT

Overview

The CDCLVD2102RGTT is a low jitter, dual 1:2 universal-to-LVDS buffer manufactured by Texas Instruments. It accepts differential inputs compatible with LVCMOS, LVDS, and LVPECL standards, converting them to differential LVDS outputs. The device supports a maximum frequency of 800 MHz and operates on a supply voltage range of 2.375 V to 2.625 V. Housed in a 16-VQFN (3x3 mm) package with an exposed pad, it functions within an industrial temperature range of -40°C to +85°C. This component serves as a fanout buffer for clock distribution applications requiring low skew and high-speed signal integrity.

Feature Summary

• Dual 1:2 Universal Input Compatibility: Supports LVCMOS, LVDS, and LVPECL input signals.
• LVDS Output Generation: Converts universal inputs to differential LVDS outputs.
• High-Speed Performance: Operates at frequencies up to 800 MHz.
• Compact Packaging: Available in a 16-pin VQFN (3mm x 3mm) surface-mount package.

Applications

• Clock distribution networks in communication systems
• Fanout buffering for high-speed digital interfaces
• Signal translation between different logic families

Procurement Notes

Verify the specific ordering suffix 'RGTT' against the manufacturer's official documentation to confirm tape and reel packaging details. Ensure the supply voltage requirements (2.375 V to 2.625 V) align with the target system design. Confirm thermal management needs for the 16-VQFN package during operation.

Selection Notes

Select this component when a dual-channel buffer is required to drive LVDS loads from mixed-signal sources like LVCMOS or LVPECL. The 800 MHz maximum frequency suits moderate-speed clock distribution. Verify that the narrow supply voltage window fits the available power rails. Consider the 16-VQFN footprint for PCB layout constraints.

Part Context

This part belongs to the CDCLVD series of low-jitter buffers from Texas Instruments. It shares functional similarities with other members like the CDCLVP2102 but differs in output type (LVDS vs. LVPECL). The RGTT suffix typically denotes a specific tape and reel quantity or variant within the standard product line.

Replacement Considerations

Direct replacements include other Texas Instruments dual 1:2 LVDS buffers such as the CDCLVD2102RGTR if packaging differences are acceptable. Cross-compatibility with similar family members requires verifying pinout and electrical parameter alignment.
