CDC536DBRG4 Equivalent & Substitute Parts

Part Overview

The CDC536DBRG4 is a PLL Clock Driver IC manufactured by Texas Instruments, designed for clock distribution and timing applications requiring TTL input and LVTTL output. This device operates at frequencies up to 100MHz with a 1:6 input-to-output ratio and integrated divider/multiplier functionality. The CDC536DBRG4 is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the CDC536DBRG4 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CDC536DBR maintains identical specifications in the following key areas:

  • Package type and physical dimensions (28-SSOP)
  • Input/output signal compatibility (TTL input, LVTTL output)
  • Maximum operating frequency (100MHz)
  • Input-to-output ratio (1:6)
  • Supply voltage range (3V ~ 3.6V)
  • Operating temperature range (0°C ~ 70°C)
  • Integrated PLL with bypass capability
  • Divider and multiplier functionality
  • Compliance certifications (ROHS3, REACH Unaffected)

The CDC536DBR differs only in product status (Active vs. Discontinued), making it a direct functional equivalent for new designs and replacement applications.

Engineering Selection Recommendations

The CDC536DBR is the direct substitute for CDC536DBRG4 applications. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications. The CDC536DBR is currently in active production status, ensuring availability for new designs and replacement stock requirements.

Both parts meet ROHS3 compliance and REACH regulatory requirements, making them suitable for applications subject to environmental and hazardous substance restrictions. The MSL rating of 1 (Unlimited) indicates minimal moisture sensitivity, reducing handling and storage constraints during manufacturing and assembly processes.

Selection between these parts should be based on availability and supply chain requirements, as they are functionally equivalent across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can CDC536DBR be used as a direct replacement for CDC536DBRG4?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including package type, signal levels, frequency rating, supply voltage, and operating temperature range.

Q: Are there any differences in compliance or certifications?

A: No. Both CDC536DBRG4 and CDC536DBR carry identical ROHS3 compliance and REACH Unaffected status. Both have MSL rating of 1 (Unlimited).

Q: What is the primary reason for substitution?

A: The CDC536DBRG4 is discontinued at DiGi Electronics. The CDC536DBR remains in active production and provides equivalent functionality for ongoing applications.

Q: Are the packages physically identical?

A: Yes. Both parts use the 28-SSOP package with 0.209" width and 5.30mm dimensions, ensuring PCB layout and assembly compatibility.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is determined by matching package type, input/output signal compatibility (TTL/LVTTL), maximum frequency (100MHz), supply voltage range (3V ~ 3.6V), operating temperature range (0°C ~ 70°C), and integrated PLL with bypass functionality.
