CDCLVP2108RGZT

Overview

The CDCLVP2108RGZT is a high-performance clock buffer manufactured by Texas Instruments, designed for distributing low-power LVPECL signals. It features a single differential input and sixteen LVPECL outputs, providing a 1:16 fanout ratio. The device supports input signal formats including LVCMOS, LVDS, LVPECL, and LVTTL, with a maximum operating frequency of 2 GHz. It operates within a supply voltage range of 2.375 V to 3.6 V and is housed in a 48-VQFN package with an exposed pad. The component is rated for industrial temperatures from -40°C to 85°C.

Feature Summary

• 16 LVPECL Outputs: Provides sixteen low-voltage positive emitter-coupled logic outputs for robust signal distribution.
• High-Speed Performance: Supports clock frequencies up to 2 GHz with low propagation delay characteristics.
• Flexible Input Compatibility: Accepts multiple input standards including LVCMOS, LVDS, LVPECL, and LVTTL.
• Compact Packaging: Utilizes a 48-VQFN (7x7 mm) surface-mount package with an exposed thermal pad.

Applications

• High-speed data communication systems requiring precise clock distribution.
• Wireless infrastructure base stations and small cells.
• Test and measurement equipment utilizing high-frequency timing references.
• Medical imaging systems demanding low-jitter clock signals.

Procurement Notes

Verify the specific ordering suffix 'RGZT' against the manufacturer's official datasheet to confirm tape and reel packaging specifications. Ensure the selected variant matches the required temperature grade and pin configuration for the target PCB layout. Cross-reference the part number with authorized distributors to confirm current availability and lead times.

Selection Notes

Select this component when a single source clock must drive sixteen LVPECL loads simultaneously. Confirm that the system power supply can maintain the 2.375 V to 3.6 V range under all load conditions. Evaluate the thermal requirements of the 48-VQFN package, as the exposed pad requires adequate copper area for heat dissipation during operation at maximum frequencies.

Part Context

This part belongs to the CDCLVP series of high-performance clock buffers from Texas Instruments. These devices are engineered for applications requiring low jitter and flexible input/output configurations. The CDCLVP2108 specifically addresses designs needing significant fanout capabilities while maintaining signal integrity across high-speed digital interfaces.

Replacement Considerations

Direct replacements include other Texas Instruments parts from the CDCLVP family, such as the CDCLVP2108RGZR, which shares identical electrical characteristics but may differ in packaging quantity or reel specifications. Verify pin-to-pin compatibility and electrical parameters before substituting.
