CDC2536DBG4

Overview

The CDC2536DBG4 is a PLL-based clock driver manufactured by Texas Instruments, housed in a 28-SSOP package. It operates on a single 3V to 3.6V supply and supports frequencies up to 100MHz within an operating temperature range of 0°C to 70°C. The device features one circuit with a 1:6 input-to-output ratio, utilizing TTL inputs and LVTTL outputs. It includes integrated frequency dividers and multipliers, allowing for flexible clock signal generation and distribution in digital systems without requiring external components for basic operation.

Feature Summary

• Integrates a Phase-Locked Loop (PLL) circuit for precise clock signal generation and jitter reduction
• Provides multiple frequency options including 1/2x, 1x, and 2x multiplication/division capabilities
• Supports standard TTL input logic levels while delivering LVTTL output signals
• Designed for surface-mount installation in compact electronic assemblies

Applications

• Clock distribution networks in high-speed digital processing systems
• Frequency synthesis for communication equipment requiring stable timing references
• System synchronization in embedded controllers and industrial automation modules

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'G4' indicates lead-free and RoHS compliance status as per current Texas Instruments standards. Ensure storage conditions adhere to moisture sensitivity level 1 requirements to prevent package damage before reflow soldering.

Selection Notes

Select this component when a single-channel PLL clock driver with 1:6 fan-out is required. Ensure the system voltage remains within the 3V to 3.6V range. Verify that the 28-SSOP package dimensions fit the PCB layout constraints. Confirm compatibility between TTL input requirements and the source clock signal levels.

Part Context

This part belongs to the CDC2536 family of clock drivers from Texas Instruments. It shares functional similarities with other members like the CDC2536DBRG4 but may differ in packaging or environmental compliance specifications. The base model CDC2536 represents the core architecture used across various industrial and commercial timing applications.

Replacement Considerations

The CDC536DBG4 is listed as a discontinued alternative with no current stock. The CDC536DB is identified as a manufacturer-recommended substitute, though availability should be verified. Cross-check pinouts and electrical characteristics before substitution.
