CDC2536DB

Overview

The CDC2536DB is a clock driver and frequency synthesizer manufactured by Texas Instruments, housed in a 28-pin SSOP package. It operates as a PLL-based clock generator with a single circuit configuration. The device accepts TTL input signals and provides LVTTL output levels. It supports a maximum operating frequency of 100 MHz and functions within a supply voltage range of 3 V to 3.6 V. The component is rated for an industrial temperature range of 0°C to 70°C. It integrates both divider and multiplier capabilities for frequency synthesis applications.

Feature Summary

• Integrates a Phase-Locked Loop (PLL) for precise clock signal generation and frequency synthesis.
• Provides flexible frequency division and multiplication ratios to adapt input clocks to system requirements.
• Features TTL-compatible inputs and LVTTL outputs for direct interfacing with digital logic circuits.

Applications

• Clock distribution networks requiring frequency synthesis
• Digital systems needing stable clock sources from lower-frequency references
• Embedded controllers utilizing PLL-based timing solutions

Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet to confirm package type and temperature rating. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for obsolescence notices or lifecycle changes directly from Texas Instruments documentation before finalizing procurement plans.

Selection Notes

Select this component when a single-channel PLL clock driver with TTL input and LVTTL output is required. Ensure the design operates within the 3 V to 3.6 V supply range and 100 MHz maximum frequency limit. Verify that the 28-SSOP package fits the PCB layout constraints and thermal requirements of the application.

Part Context

The CDC2536 belongs to the CDC25xx series of clock drivers and frequency synthesizers from Texas Instruments. This family focuses on providing versatile clock management solutions using PLL technology. The DB suffix indicates the specific 28-SSOP surface-mount package variant used for this part number.

Replacement Considerations

Consult the official Texas Instruments replacement guide for the CDC2536 series. Verify pin-to-pin compatibility and electrical parameter equivalence with any proposed substitute components before implementation.
