CDC319DBRG4

Overview

The CDC319DBRG4 is a clock buffer and driver manufactured by Texas Instruments, designed for high-speed signal distribution. It features a single input to ten output configuration with an LVTTL input interface and LVTTL/TTL output capabilities. The device operates within a supply voltage range of 3.135V to 3.465V and supports frequencies up to 100 MHz. Packaged in a 28-SSOP surface-mount case, it functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• 1-to-10 fanout buffer configuration for clock distribution
• LVTTL input compatible with LVTTL and TTL outputs
• Maximum operating frequency of 100 MHz
• Operates on a 3.135V to 3.465V supply voltage

Applications

• Clock distribution networks requiring 1:10 splitting
• System timing architectures using LVTTL standards
• High-frequency digital circuit synchronization

Procurement Notes

Verify the specific package variant, as the part number suffix indicates tape and reel packaging. Confirm that the required supply voltage aligns with the specified 3.135V to 3.465V range. Ensure the design accommodates the 0°C to 70°C operating temperature limits for the intended application environment.

Selection Notes

Select this component when a single clock source must drive ten downstream loads using LVTTL logic levels. The fixed 100 MHz maximum frequency and narrow voltage supply requirements distinguish it from wider-range buffers. Verify pin compatibility with the 28-SSOP footprint during PCB layout.

Part Context

This component belongs to the CDC319 series of clock drivers. It serves as a specialized solution for distributing a single clock line to multiple destinations within a system. The DBRG4 suffix denotes the specific 28-SSOP package and tape-and-reel manufacturing format provided by Texas Instruments.

Replacement Considerations

Direct replacements include other CDC319 variants such as CDC319DB or CDC319DBR, which share identical electrical characteristics but may differ in packaging or environmental ratings.
