CDC536DB

Overview

The CDC536DB is a PLL clock driver IC manufactured by Texas Instruments, housed in a 28-SSOP package. It operates within a supply voltage range of 3V to 3.6V and supports a maximum frequency of 100MHz. The device features one circuit with a 1:6 input-to-output ratio, utilizing TTL inputs and LVTTL outputs. It includes integrated divider and multiplier functions for frequency synthesis. The component is designed for surface mount installation and functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrates phase-locked loop (PLL) technology for precise clock signal generation and distribution.
• Provides flexible frequency manipulation through built-in divider and multiplier capabilities.
• Supports standard logic interfaces with TTL inputs and LVTTL outputs for system compatibility.

Applications

• Clock distribution networks requiring frequency synthesis
• Digital systems needing stable clock drivers
• Embedded electronics utilizing PLL-based timing solutions

Procurement Notes

Verify the current lifecycle status before procurement as availability may vary. Confirm that the 28-SSOP package dimensions align with the target PCB footprint. Ensure the 3V to 3.6V supply voltage range matches the system power architecture. Validate that the 100MHz maximum frequency meets the design requirements. Check for RoHS compliance if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a single-channel PLL clock driver with frequency multiplication and division is required. The 28-SSOP package suits applications with limited board space. Ensure the system operates within the specified 0°C to 70°C temperature range. Verify that TTL input and LVTTL output levels are compatible with connected logic devices. Consider the 1:6 output ratio when designing the clock tree structure.

Part Context

The CDC536DB belongs to the CDC536 family of clock drivers from Texas Instruments. This series focuses on providing robust clock signal management with integrated PLL functionality. The device serves as a key component in timing circuits where frequency synthesis and distribution are critical. It complements other clock generators and synthesizers in complex digital systems.

Replacement Considerations

The CDC536DBG4 is listed as a manufacturer-recommended substitute. Verify pinout and electrical specifications match before substitution. Ensure the replacement part meets the same package and thermal requirements.
