CDCLVP110VFRG4

Overview

The CDCLVP110VFRG4 is a low-voltage clock buffer and driver manufactured by Texas Instruments. It provides a 2:10 fanout ratio, accepting differential inputs in HSTL or LVPECL formats and distributing them as LVPECL outputs. The device supports maximum frequencies up to 3.5 GHz with a supply voltage range of 2.375 V to 3.8 V. Packaged in a 32-LQFP (7x7 mm) case, it operates within an industrial temperature range of -40°C to +85°C. This component functions as a multiplexer-based fanout buffer designed for high-speed clock distribution applications requiring precise signal integrity.

Feature Summary

• 2:10 Fanout Ratio: Accepts two differential input sources and distributes the selected signal to ten LVPECL outputs.
• High-Speed Performance: Supports clock frequencies up to 3.5 GHz with low skew characteristics suitable for critical timing paths.
• Flexible Input Compatibility: Accepts both HSTL and LVPECL differential input signals, allowing integration with various source standards.
• Low-Voltage Operation: Designed for power efficiency with a supply voltage range of 2.375 V to 3.8 V.

Applications

• High-speed data converter clock distribution
• FPGA and ASIC clock tree generation
• Telecommunications equipment synchronization
• Test and measurement instrument timing systems

Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's current datasheet to confirm lead-free status and RoHS compliance details. Ensure the package variant matches the required 32-LQFP dimensions (7x7 mm) for PCB footprint compatibility. Confirm that the operating temperature range of -40°C to +85°C meets the environmental requirements of the target application system.

Selection Notes

Select this component when a 2:10 fanout is required with support for both HSTL and LVPECL inputs. Compare against the CDCLVP110MVFR if a different output configuration or pinout is needed. Ensure the system power supply can maintain stability within the 2.375 V to 3.8 V range to guarantee the 3.5 GHz maximum frequency performance without degradation.

Part Context

This part belongs to the CDCLVP series of low-voltage clock drivers from Texas Instruments. It is functionally related to the CDCLVP110VFR, with the 'G4' suffix typically indicating a lead-free and RoHS-compliant version. It serves as a specialized solution for distributing high-frequency clocks in complex digital systems where multiple synchronized outputs are necessary.

Replacement Considerations

Check for direct substitutes like the CDCLVP110VFR, ensuring pinout and electrical specifications match. Verify if the CDCLVP111 offers compatible functionality with selectable input features if additional flexibility is required. Always validate thermal and electrical parameters against the original design constraints before substitution.
