CDCLVD1212RHAT

Overview

The CDCLVD1212RHAT is a low additive jitter LVDS buffer manufactured by Texas Instruments. It features a 2:12 fanout ratio, accepting differential inputs and providing twelve LVDS outputs. The device supports input signal formats including LVCMOS, LVDS, and LVPECL. It operates within a supply voltage range of 2.375 V to 2.625 V and supports maximum 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 configuration
• Supports LVCMOS, LVDS, and LVPECL input types
• Twelve LVDS differential outputs
• Maximum frequency of 800 MHz

Applications

• Clock distribution networks requiring low jitter
• High-speed data acquisition systems
• Telecommunications infrastructure

Procurement Notes

Verify the specific ordering suffix RHAT corresponds to the Tape & Reel packaging format. Confirm that the 40-VQFN (6x6) package dimensions match the target PCB layout requirements. Ensure the supply voltage constraints of 2.375 V to 2.625 V are compatible with the system power design before procurement.

Selection Notes

Select this component when a 2:12 fanout ratio with LVDS outputs is required. It is suitable for applications needing support for multiple input standards such as LVCMOS, LVDS, or LVPECL. The 800 MHz maximum frequency and -40°C to +85°C operating range define its environmental and performance limits compared to higher-frequency alternatives.

Part Context

This part belongs to the CDCLVD series of clock buffers from Texas Instruments. It serves as a fanout buffer designed to distribute high-frequency clock signals with minimal added jitter. The RHAT suffix indicates the specific reel-based packaging variant of the CDCLVD1212 device.

Replacement Considerations

The CDCLVD1208 offers a similar function with an 8-output configuration. The CDCLVD1216 provides a 16-output alternative. Both share the same series characteristics but differ in output count.
