CDC536DBG4 PLL Clock Driver IC Equivalent & Substitute Parts

Part Overview

The CDC536DBG4 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 CDC536DBG4 is discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDC536DBG4 is determined by strict equivalence across the following critical parameters:

• Package / Case: 28-SSOP (0.209", 5.30mm Width) — physical and electrical compatibility
• Input Signal Type: TTL — signal level compatibility with source devices
• Output Signal Type: LVTTL — signal level compatibility with load devices
• Frequency - Max: 100MHz — operational bandwidth requirement
• Ratio - Input:Output: 1:6 — clock distribution ratio
• Voltage - Supply: 3V ~ 3.6V — power supply compatibility
• Operating Temperature: 0°C ~ 70°C — thermal operating range
• PLL with Bypass: Yes — functional architecture requirement
• Divider/Multiplier: Yes/Yes — frequency manipulation capability

The CDC536DB is identified as a manufacturer-recommended substitute. This part maintains identical electrical specifications, functional characteristics, and package configuration as the CDC536DBG4, with the primary distinction being product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The CDC536DB is the direct equivalent substitute for the CDC536DBG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, functional architecture, and physical packaging. The CDC536DB maintains active product status, ensuring continued availability and supply chain support compared to the discontinued CDC536DBG4.

Both parts comply with ROHS3 and REACH standards, with MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling. Selection between these parts should be based on procurement availability and supply chain requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the CDC536DB be used as a direct replacement for the CDC536DBG4?

A: Yes. The CDC536DB is electrically and mechanically equivalent to the CDC536DBG4. All critical parameters including package type, signal levels, frequency rating, supply voltage, and operating temperature range are identical.

Q: What is the difference between CDC536DBG4 and CDC536DB?

A: The primary difference is product status. The CDC536DBG4 is discontinued at DiGi Electronics, while the CDC536DB maintains active status. Both parts are manufactured by Texas Instruments with identical specifications and 28-SSOP packaging.

Q: Are there any compatibility concerns when substituting CDC536DB for CDC536DBG4?

A: No compatibility concerns exist. Both parts feature identical TTL input, LVTTL output, 100MHz maximum frequency, 1:6 input-to-output ratio, 3V to 3.6V supply voltage range, and 0°C to 70°C operating temperature range. PCB layout and circuit design require no modification.

Q: What packaging formats are available for these parts?

A: Both the CDC536DBG4 and CDC536DB are supplied in 28-SSOP (0.209", 5.30mm Width) surface mount packages in tube packaging format.

Q: Are moisture sensitivity or environmental compliance concerns relevant to this substitution?

A: Both parts carry MSL rating 1 (Unlimited) and are ROHS3 compliant and REACH unaffected. No additional handling or environmental precautions are required beyond standard ESD protection for surface mount components.
