CDCLVC1310RHBR

Overview

The CDCLVC1310RHBR is a single-circuit clock buffer manufactured by Texas Instruments, designed for low-voltage CMOS applications. It features a 3:10 fanout ratio, accepting one input to drive ten outputs. The device supports multiple input standards including HCSL, LVCMOS, LVDS, LVPECL, SSTL, and crystal inputs, while providing LVCMOS outputs. It operates within a supply voltage range of 2.375 V to 3.465 V and supports maximum frequencies of 200 MHz for both input and output signals. The component is housed in a 32-VQFN package with an exposed pad and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports diverse input protocols: HCSL, LVCMOS, LVDS, LVPECL, SSTL, and XTAL
• Provides 10 LVCMOS outputs from a single input source
• Operates at maximum frequencies up to 200 MHz
• Compatible with 2.375 V to 3.465 V power supplies

Applications

• Clock distribution networks requiring high fanout
• Systems utilizing HCSL or LVDS clock sources
• Low-voltage digital logic interfaces
• Embedded systems needing precise timing distribution

Procurement Notes

Verify the specific ordering suffix 'RHBR' corresponds to the required tape and reel packaging configuration. Confirm that the 32-VQFN (5x5) package dimensions align with the target PCB footprint. Ensure the design accommodates the specified 2.375 V to 3.465 V supply voltage range and thermal requirements for the -40°C to +85°C operating environment.

Selection Notes

Select this component when a single clock source must be distributed to ten downstream LVCMOS loads. It is suitable for designs requiring compatibility with various differential and single-ended input standards such as LVDS or HCSL. The 200 MHz frequency capability makes it appropriate for moderate-speed digital systems. Verify that the 32-pin QFN package is feasible for the assembly process.

Part Context

This part belongs to the CDCLVC1310 series of clock buffers. It serves as a fanout buffer and distribution element within clock and timer IC categories. The device integrates a single circuit to manage signal integrity across multiple output lines, functioning as a multiplexer or buffer depending on the specific system configuration requirements.

Replacement Considerations

Check for other parts within the CDCLVC1310 family that may offer different pin counts or input/output configurations. Verify if alternative packages are available for the same functional specification.
