CDCLVD2106RHAT

Overview

The CDCLVD2106RHAT is a low jitter, dual 1:6 universal-to-LVDS buffer manufactured by Texas Instruments. It features two independent buffers, each providing six LVDS outputs from universal inputs compatible with LVCMOS, LVDS, and LVPECL standards. The device operates within a supply voltage range of 2.375 V to 2.625 V and supports maximum input frequencies up to 800 MHz. Packaged in a 40-VQFN (6x6) exposed pad format, it is designed for surface mount applications across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual 1:6 configuration with universal input support for LVCMOS, LVDS, and LVPECL
• Low additive jitter performance optimized for high-speed clock distribution
• Operates on a single 2.5 V supply (2.375 V to 2.625 V)
• Maximum input frequency capability of 800 MHz

Applications

• High-speed data converter clock distribution
• FPGA and ASIC clock buffering
• Telecommunications equipment timing networks
• Test and measurement instrument clocking

Procurement Notes

Verify the specific suffix RHAT against the manufacturer's official datasheet to confirm tape-and-reel packaging quantities and handling specifications. Ensure that the 40-VQFN thermal pad requirements are addressed in the PCB layout design to maintain reliable operation within the specified -40°C to +85°C temperature range.

Selection Notes

Select this component when a dual-channel buffer with six outputs per channel is required for LVDS signaling. Confirm that the system power supply can be tightly regulated between 2.375 V and 2.625 V to ensure optimal jitter performance. Verify that the input signal levels match the supported LVCMOS, LVDS, or LVPECL standards before integration.

Part Context

This part belongs to the CDCLVD series of low jitter clock buffers from Texas Instruments. It serves as a fanout buffer solution for distributing reference clocks to multiple downstream components. The device is distinct from other series members by its specific 1:6 ratio and universal input compatibility, targeting applications requiring precise timing distribution over multiple lines.

Replacement Considerations

Direct replacements within the same family include CDCLVD2102, CDCLVD2104, and CDCLVD2108, which offer different output ratios (1:2, 1:4, and 1:8 respectively). Cross-family alternatives such as LMK1D2106LRHAT may provide similar functionality but require verification of pin compatibility and electrical parameters.
