CDC536DBRG4

Overview

The CDC536DBRG4 is a PLL clock driver manufactured by Texas Instruments, designed for frequency synthesis and distribution. 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 with a 1:6 input-to-output ratio, utilizing TTL inputs and LVTTL outputs. It includes integrated divider and multiplier capabilities, 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 phase-locked loop technology for precise clock signal generation and distribution
• Provides configurable frequency division and multiplication options including half-speed, full-speed, and double-speed outputs
• Supports standard TTL input logic levels while delivering LVTTL output signals

Applications

• Clock distribution networks requiring frequency synthesis
• System timing architectures needing multiple clock phases from a single source
• Digital circuits requiring stable clock signals up to 100MHz

Procurement Notes

Verify the specific suffix 'G4' against current manufacturer documentation to confirm RoHS compliance status and lead-free material composition. Confirm that the 28-SSOP package dimensions match the design footprint requirements. Check for any recent lifecycle notices or obsolescence warnings directly from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this component when a single-input, six-output clock driver with internal frequency control is required. Ensure the system power supply remains strictly between 3V and 3.6V to maintain operational integrity. Verify that the 0°C to 70°C commercial temperature range meets the environmental constraints of the target application board.

Part Context

This part belongs to the CDC536 family of PLL clock drivers from Texas Instruments. It shares core functional specifications with variants such as CDC536DBG4 and CDC536DB, differing primarily in packaging or manufacturing lot details. The device serves as a specialized solution for generating multiple synchronized clock signals from a single reference input.

Replacement Considerations

The CDC536DB is listed as a manufacturer-recommended alternative. Verify pin compatibility and electrical parameter equivalence before substitution.
