CDCLVP1212RHAR

Overview

The CDCLVP1212RHAR is a low additive jitter clock buffer manufactured by Texas Instruments. It features a 2:12 fanout ratio, converting two differential inputs into twelve LVPECL outputs. The device supports input signals including LVCMOS, LVDS, LVPECL, and LVTTL. It operates within a supply voltage range of 2.375 V to 3.6 V and supports maximum frequencies up to 2 GHz. Designed for surface mount assembly, it is housed in a 40-VQFN package with dimensions of 6x6 mm. The component functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• 2:12 Fanout Ratio: Distributes two differential input signals to twelve LVPECL outputs.
• Low Additive Jitter: Optimized for high-speed clock distribution applications requiring signal integrity.
• Flexible Input Compatibility: Accepts LVCMOS, LVDS, LVPECL, and LVTTL input formats.
• Wide Supply Range: Operates on a single supply voltage from 2.375 V to 3.6 V.

Applications

• High-speed data converter clock distribution
• FPGA and ASIC clock tree generation
• Telecommunications equipment timing networks

Procurement Notes

Verify the specific ordering suffix RHAR confirms the Tape & Reel packaging format. Ensure the design accommodates the 40-VQFN exposed pad thermal requirements. Confirm that the LVPECL output swing matches the load impedance specifications of the downstream components. Check for any RoHS compliance documentation if required by the manufacturing facility standards.

Selection Notes

Select this component when a 2:12 distribution ratio is required with LVPECL outputs. Ensure the system power supply can maintain the 2.375 V to 3.6 V range under all load conditions. Verify that the input signal levels are compatible with the supported LVCMOS, LVDS, LVPECL, or LVTTL standards. Consider the 40-VQFN package size for PCB layout constraints.

Part Context

This part belongs to the CDCLVP series of clock buffers designed for low jitter performance. It serves as a critical component in timing architectures where signal skew and noise must be minimized. The device complements other Texas Instruments clocking solutions by providing high-channel count distribution from a single source.

Replacement Considerations

Direct replacements include the CDCLVP1212RHAT variant, which shares identical electrical characteristics but differs in packaging configuration. Evaluate pin-to-pin compatibility and thermal performance when substituting packages within the same family.
