CDC516DGGR

Overview

The CDC516DGGR is a clock driver and distribution component manufactured by Texas Instruments, belonging to the CDC516 series. It operates within a supply voltage range of 2.375 V to 3.8 V and supports an input frequency up to 400 MHz. The device features multiple multiplication and division factors, including 1:2, 1:4, 1:5, 1:6, 1:8, and 1:10. It utilizes a TSSOP-48 surface-mount package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Supports flexible clock signal scaling with various integer multiplication and division ratios
• Capable of processing high-frequency clock inputs up to 400 MHz
• Designed for low-voltage operation compatible with standard digital logic levels

Applications

• Clock distribution in high-speed data communication systems
• Frequency synthesis and jitter attenuation in networking equipment
• System timing generation for processors and memory interfaces

Procurement Notes

Verify the specific suffix DGGR against the manufacturer's official datasheet to confirm the TSSOP-48 packaging and reel/cut-tape delivery format. Ensure the order matches the exact part number to avoid discrepancies in pinout or electrical characteristics compared to other variants in the CDC516 family.

Selection Notes

Select this component when a single-output clock driver with programmable frequency scaling is required. Compare the 400 MHz maximum input frequency and specific division ratios against system requirements. Evaluate the TSSOP-48 package constraints against available PCB space and thermal management capabilities.

Part Context

The CDC516DGGR is part of the broader CDC516 family of clock drivers. This series provides versatile solutions for generating precise clock signals from reference sources. The DGGR variant specifically denotes the TSSOP-48 package configuration, distinguishing it from other physical form factors available within the same functional family.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Potential alternatives may include other members of the CDC516 series with different package options or similar clock drivers from the same product line that match the required voltage and frequency specifications.
