CDCVF111FNG4

Clock Buffers, Drivers Overview

The CDCVF111FNG4 is a differential LVPECL clock driver manufactured by Texas Instruments. It provides a 1:9 fan-out configuration, converting a single differential input into nine differential outputs. The device operates within a supply voltage range of 3.0 V to 3.6 V and supports input frequencies up to 650 MHz. It is housed in a 28-pin PLCC package with dimensions of 11.51 mm x 11.51 mm and a height of 4.06 mm. The component dissipates up to 525 mW and is designed for high-speed clock distribution applications requiring low skew and precise timing.

Clock Buffers, Drivers Feature Summary

• 1:9 differential LVPECL clock driver architecture
• Supports input frequencies up to 650 MHz
• Operates on a 3.0 V to 3.6 V power supply
• Available in a 28-pin PLCC package

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• Differential LVPECL signal buffering
• System timing synchronization

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current datasheet to confirm lead-free compliance and packaging details. Ensure the 28-pin PLCC footprint matches the target PCB design. Confirm availability through authorized distributors as stock levels vary.

Clock Buffers, Drivers Selection Notes

Select this component when a single differential source must drive nine LVPECL loads. Verify that the system power supply remains within the 3.0 V to 3.6 V range. Check that the required operating frequency does not exceed 650 MHz. Ensure the thermal dissipation of 525 mW is manageable within the enclosure.

Clock Buffers, Drivers Part Context

This part belongs to the CDCVF111 family of differential clock drivers. It serves as a direct replacement for the non-green variant CDCVF111FN. The device is functionally equivalent to other 1:9 LVPECL drivers from manufacturers such as ON Semiconductor (MC10E111) and Fairchild (100311), though pinouts and electrical characteristics should be compared carefully.

Clock Buffers, Drivers Replacement Considerations

The CDCVF111FN is the non-lead-free predecessor. Cross-reference with MC10E111 or SY10E111 for alternative sourcing, but verify pin compatibility and electrical specifications before substitution.
