CDC536DBR

Overview

The CDC536DBR is a PLL-based clock driver manufactured by Texas Instruments, housed in a 28-SSOP surface-mount package. It operates on a single 3V to 3.6V supply and supports frequencies up to 100MHz. 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, functioning as a clock generator and synthesizer within the commercial temperature range of 0°C to 70°C.

Feature Summary

• Integrates programmable frequency division and multiplication capabilities for precise clock signal generation.
• Converts TTL input signals to LVTTL output levels for compatibility with low-voltage logic systems.
• Provides a single-channel architecture designed for efficient clock distribution in digital circuits.

Applications

• Clock signal generation and distribution in high-speed digital systems
• Frequency synthesis for timing-critical applications
• Interface bridging between TTL and LVTTL logic domains

Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when sourcing components. Confirm RoHS3 compliance status through official manufacturer documentation or authorized distributors. Ensure the selected variant matches the required 28-SSOP footprint and electrical specifications for your design.

Selection Notes

Select this component when a single PLL clock driver with 1:6 ratio is required. Verify that the 3V to 3.6V supply voltage aligns with system power rails. Ensure the 100MHz maximum frequency meets timing requirements. Check for availability of the tube or reel packaging options based on assembly needs.

Part Context

This part belongs to the CDC536 family of PLL clock drivers from Texas Instruments. It shares core functionality with variants like CDC536DBG4 and CDC536DB, differing primarily in packaging and environmental compliance suffixes. The family is designed for general-purpose clock generation and distribution tasks.

Replacement Considerations

The CDC536DB is listed as a manufacturer-recommended alternative. Verify pinout compatibility and electrical parameters before substitution. Other family members may require verification of packaging differences and specific suffix meanings.
