CDC2536DBRG4

Overview

The CDC2536DBRG4 is a 3.3V PLL-based clock driver manufactured by Texas Instruments, designed for frequency synthesis and distribution applications. It operates within a supply voltage range of 3V to 3.6V and supports a maximum frequency of 100MHz. The device features a single circuit configuration with a 1:6 input-to-output ratio, providing both divide and multiply capabilities. It utilizes TTL inputs and LVTTL outputs, housed in a 28-SSOP package measuring 0.209 inches (5.30mm) in width. The component functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrates a Phase-Locked Loop (PLL) for precise clock signal generation and frequency manipulation.
• Provides flexible frequency options including half-speed, full-speed, and double-speed multiplication/division factors.
• Supports standard TTL input logic levels while delivering LVTTL output signals for system compatibility.

Applications

• Clock distribution networks requiring frequency multiplication or division.
• System timing architectures utilizing 3.3V power domains.
• Digital signal processing interfaces needing stable clock sources.

Procurement Notes

Verify the specific suffix 'G4' against current manufacturer documentation to confirm RoHS compliance status and lead time requirements. Confirm package availability as inventory levels fluctuate. Ensure the 28-SSOP footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a single-channel PLL clock driver with 1:6 fan-out is required for 3.3V systems. Verify that the 100MHz maximum frequency meets the system's timing specifications. Ensure the 28-SSOP package dimensions fit the available board space and thermal management requirements.

Part Context

This part belongs to the CDC2536 family of clock drivers from Texas Instruments. It shares functional similarities with other devices in the series but is distinguished by its specific 3.3V operation and 28-SSOP packaging. It serves as a specialized solution for frequency synthesis in mid-range digital systems.

Replacement Considerations

The CDC536DB is listed as a manufacturer-recommended alternative. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure the replacement part meets the same voltage and frequency requirements for the specific application.
