CDC516DGGG4

Overview

The CDC516DGGG4 is a zero-delay fanout buffer manufactured by Texas Instruments, designed for high-speed clock distribution in digital systems. It accepts a single differential input and provides sixteen low-voltage differential signaling (LVDS) outputs. The device operates within a supply voltage range of 3.0 V to 3.6 V and supports data rates up to 800 MHz. It is housed in a 64-pin Thin-Shrink Small Outline Package (TSSOP) with a thermal pad, ensuring reliable performance across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides sixteen LVDS outputs from a single differential input for efficient clock fanout
• Zero-delay architecture maintains phase alignment between input and output clocks
• Supports high-frequency operation suitable for demanding digital applications

Applications

• High-speed data acquisition systems requiring precise clock synchronization
• Telecommunications infrastructure equipment
• Industrial automation control units

Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free compliance and RoHS status. Confirm the specific package variant matches the design requirements. Ensure the supplier source is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a single differential clock source must drive multiple LVDS loads with minimal skew. Verify that the system power supply falls within the specified 3.0 V to 3.6 V range. Ensure the PCB layout accommodates the 64-pin TSSOP footprint and thermal management needs.

Part Context

This component belongs to the CDC516 family of clock buffers. It serves as a critical interface element for distributing reference clocks in complex digital circuits. The device complements other clock generation components by providing signal integrity and fanout capability.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify electrical specifications such as output current and operating voltage before substituting. Ensure any replacement maintains the required LVDS standard compatibility.
