CDCLVD1212RHAR

Overview

The CDCLVD1212RHAR is a low additive jitter LVDS fanout buffer manufactured by Texas Instruments. It features a 2:12 configuration with two selectable differential clock inputs and twelve low skew outputs. The device supports input signal levels including LVCMOS, LVDS, and LVPECL, while providing LVDS outputs. It operates within a supply voltage range of 2.375 V to 2.625 V and functions at frequencies up to 800 MHz. The component is housed in a 40-VQFN package with an exposed pad, designed for surface mount applications across an operating temperature range of -40°C to +85°C.

Feature Summary

• 2:12 Low Additive Jitter LVDS Buffer architecture
• Supports LVCMOS, LVDS, and LVPECL input levels
• Operates on 2.375 V to 2.625 V supply voltage
• Maximum frequency of 800 MHz

Applications

• Clock distribution networks requiring low skew
• High-speed data acquisition systems
• Telecommunications equipment clocking

Procurement Notes

Verify the specific ordering suffix RHAR corresponds to the Tape & Reel packaging format as indicated in the product description. Confirm that the 40-VQFN (6x6) package dimensions match the design constraints. Ensure the 2.375 V to 2.625 V supply voltage range aligns with the target power rail specifications before procurement.

Selection Notes

Select this component when a 2-input to 12-output LVDS buffering solution is required. It is suitable for designs needing support for multiple input logic levels such as LVCMOS, LVDS, or LVPECL. The 800 MHz maximum frequency and low additive jitter characteristics make it appropriate for high-speed digital interfaces where signal integrity is critical.

Part Context

This part belongs to the CDCLVD series of clock buffers from Texas Instruments. It serves as a fanout buffer for distributing clock signals with minimal added jitter. The RHAR suffix typically denotes the reel packaging variant of the standard CDCLVD1212 device, facilitating automated assembly processes.

Replacement Considerations

The CDCLVD1212RHAR is functionally equivalent to the CDCLVD1212. Other variants in the same family include CDCLVD1204, CDCLVD1208, and CDCLVD1216, which offer different output counts.
