CDCLVD110VFR

Overview

The CDCLVD110VFR is a low-skew clock buffer and distribution component manufactured by Texas Instruments. It features a 2:10 fanout ratio, accepting differential LVDS inputs and providing ten differential LVDS outputs. The device supports maximum operating frequencies up to 1.1 GHz with a supply voltage range of 2.375 V to 2.625 V. Housed in a 32-LQFP package (7x7 mm), it operates within an industrial temperature range of -40°C to +85°C. This integrated circuit functions as a multiplexer-based clock driver designed for high-speed signal integrity applications.

Feature Summary

• 2:10 Fanout Ratio: Distributes two differential input signals to ten differential LVDS output channels.
• High-Speed Performance: Supports clock frequencies up to 1.1 GHz with low skew characteristics.
• LVDS Interface: Utilizes Low-Voltage Differential Signaling for both input and output stages to minimize noise.
• Multiplexer Functionality: Integrates selectable input capabilities for flexible clock routing.

Applications

• High-speed data communication systems requiring precise clock distribution.
• FPGA and ASIC clock tree architectures.
• Telecommunications infrastructure equipment.
• Test and measurement instruments needing low-jitter timing signals.

Procurement Notes

Verify the specific ordering suffix 'VFR' against the manufacturer's official datasheet to confirm packaging details such as tape and reel specifications. Ensure that the 32-LQFP (7x7 mm) footprint matches the target PCB layout constraints. Confirm RoHS compliance status through the latest product documentation before finalizing procurement orders.

Selection Notes

Select this component when a 2:10 differential LVDS fanout is required for frequencies approaching 1.1 GHz. Compare power consumption and skew specifications against alternative buffers if system-level jitter budgets are tight. Ensure the 2.375 V to 2.625 V supply voltage aligns with the available power rails in the design environment.

Part Context

This part belongs to the CDCLVD110 family of low-skew clock drivers. It serves as a specialized solution for distributing reference clocks in complex digital systems where signal integrity and timing precision are critical. The device complements other members of the series that may offer different fanout ratios or output logic families.

Replacement Considerations

Check for direct pin-to-pin replacements within the same TI family, such as variants with different packaging options like the CDCLVD110ARHBT. Verify electrical parameter equivalence, specifically frequency limits and supply voltage ranges, before substituting with components from other manufacturers.
