CDCLVD1216RGZT

Overview

The CDCLVD1216RGZT is a high-performance clock buffer and distribution circuit manufactured by Texas Instruments. It features a 2:16 fanout ratio, accepting differential inputs in LVCMOS, LVDS, or LVPECL formats and providing sixteen differential LVDS outputs. The device operates within a supply voltage range of 2.375V to 2.625V and supports maximum frequencies up to 800 MHz. Designed for surface mount applications, it is housed in a compact 48-VQFN (7x7 mm) package with an exposed pad. The component is rated for industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• 2:16 Fanout Ratio: Converts one input signal into sixteen synchronized output channels.
• Flexible Input Compatibility: Supports LVCMOS, LVDS, and LVPECL input logic levels.
• LVDS Output Interface: Provides sixteen differential LVDS outputs for low-power signaling.
• High-Speed Performance: Capable of operating at frequencies up to 800 MHz.

Applications

• Clock distribution networks in high-speed digital systems
• Fanout buffering for multi-channel data converters
• Synchronization circuits in telecommunications infrastructure

Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm packaging details such as Tape & Reel or Cut Tape quantities. Ensure that the 48-VQFN footprint dimensions match the target PCB layout requirements. Confirm that the 2.375V to 2.625V supply voltage range aligns with the system power design before procurement.

Selection Notes

Select this component when a single clock source must drive sixteen downstream loads requiring LVDS interfaces. Verify that the input signal type matches the supported LVCMOS, LVDS, or LVPECL standards. Ensure the application environment stays within the -40°C to +85°C temperature range and that the PCB can accommodate the 7x7 mm VQFN package with its exposed thermal pad.

Part Context

This part belongs to the CDCLVD series of clock buffers and drivers from Texas Instruments. These devices are engineered for high-frequency clock distribution tasks where signal integrity and low jitter are critical. The CDCLVD1216RGZT specifically addresses designs requiring significant fanout from a central clock source to multiple peripheral components.

Replacement Considerations

Direct replacements should be sought within the CDCLVD family or compatible Texas Instruments clock buffer series. Verify pin-to-pin compatibility and ensure that the substitute part supports the same 2:16 ratio, LVDS outputs, and input voltage specifications.
