CDC2536DBG4 Equivalent & Substitute Parts

Part Overview

The CDC2536DBG4 is a PLL Clock Driver IC manufactured by Texas Instruments, designed for clock distribution and timing applications requiring up to 100MHz frequency operation. This device features a 1:6 input-to-output ratio with integrated divider and multiplier functionality, operating from a 3V to 3.6V supply. The CDC2536DBG4 is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDC2536DBG4 is determined by strict equivalence across the following critical parameters:

• Package Type: 28-SSOP (0.209", 5.30mm Width) — physical and electrical compatibility
• Frequency Range: 100MHz maximum operation
• Input/Output Logic Levels: LVTTL on both input and output
• Supply Voltage: 3V to 3.6V operating range
• Functional Characteristics: PLL with bypass, 1:6 input-to-output ratio, integrated divider/multiplier
• Thermal Range: 0°C to 70°C operating temperature
• Compliance: ROHS3 and REACH compliance status

The CDC2536DB qualifies as a direct substitute based on identical electrical specifications, package configuration, and functional performance. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The CDC2536DB is a direct functional and electrical equivalent to the CDC2536DBG4. Both devices are manufactured by Texas Instruments and meet identical electrical specifications, thermal requirements, and compliance standards (ROHS3, REACH Unaffected).

The CDC2536DB is the preferred selection for new procurement due to its active product status. The CDC2536DBG4, while functionally equivalent, is discontinued at DiGi Electronics and should be replaced in active designs with the CDC2536DB.

Both parts maintain identical pinout, electrical performance, and package dimensions, ensuring drop-in compatibility in existing PCB layouts. The difference in packaging format (Tube versus Tape and Reel) affects only procurement and assembly handling, not electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the CDC2536DB replace the CDC2536DBG4 in existing designs?

A: Yes. The CDC2536DB is electrically and mechanically identical to the CDC2536DBG4. Both devices share the same 28-SSOP package, pinout, frequency specifications, supply voltage range, and logic levels. No design modifications are required.

Q: What is the difference between CDC2536DBG4 and CDC2536DB?

A: The primary differences are product status and packaging format. The CDC2536DBG4 is discontinued; the CDC2536DB is active. The CDC2536DBG4 is supplied in Tape and Reel format; the CDC2536DB is supplied in Tube format. Electrical and functional specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both devices.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tube versus Tape and Reel) affects only procurement, storage, and assembly handling. Electrical performance and device specifications remain identical.

Q: What is the maximum operating frequency for these devices?

A: Both the CDC2536DBG4 and CDC2536DB operate at a maximum frequency of 100MHz with a 1:6 input-to-output ratio.

Q: What supply voltage range is required?

A: Both devices operate from 3V to 3.6V supply voltage.
