CDCE706PWR Equivalent & Substitute Parts

Part Overview

The CDCE706PWR is a Spread Spectrum Clock Driver IC manufactured by Texas Instruments, designed for clock distribution and frequency synthesis applications up to 300MHz. This device features a programmable PLL with bypass capability, supporting both LVCMOS and Crystal inputs with LVCMOS outputs. The part is currently in Active product status with 35,200 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same package form factor and functional specifications. The CDC706PW represents a related device within the same product family, though with different product status and packaging configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDCE706PWR is determined by strict equivalence across the following critical parameters:

• Package Form Factor: Both main and substitute parts must use the 20-TSSOP (0.173", 4.40mm Width) surface mount package
• Electrical Specifications: Maximum frequency (300MHz), supply voltage range (3V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and input/output signal types (LVCMOS, Crystal) must be identical
• Functional Architecture: PLL configuration with bypass capability, 1:6 input-to-output ratio, and divider/multiplier functionality must match
• Compliance Standards: RoHS3 compliance and MSL rating must be maintained

The CDC706PW meets these electrical and mechanical equivalence criteria, maintaining identical package geometry, frequency specifications, voltage requirements, and functional capabilities. However, product status and packaging configuration differ between the two parts.

Engineering Selection Recommendations

CDCE706PWR is the primary selection for new designs. This part carries Active product status from Texas Instruments, indicating full support, ongoing availability, and suitability for production applications. The device is available in high volume (35,200 units) in Tape & Reel packaging, which is standard for automated assembly processes.

CDC706PW is electrically and mechanically equivalent but carries "Not For New Designs" status. This designation indicates the part is in mature or declining lifecycle phase and should not be selected for new product development. The substitute is available only in Tube packaging (652 units), which is suitable for manual assembly or low-volume applications. Selection of CDC706PW should be limited to legacy system maintenance, repair, or replacement scenarios where the original part specification must be maintained.

For applications requiring clock distribution and frequency synthesis within the specified electrical parameters, CDCE706PWR provides the optimal combination of active product status, supply availability, and standard packaging configuration.

Frequently Asked Questions (FAQ)

Q: Can CDC706PW be used as a direct replacement for CDCE706PWR in new designs?

A: No. While CDC706PW is electrically and mechanically equivalent, it carries "Not For New Designs" product status. New designs must use CDCE706PWR to ensure long-term support and supply continuity from Texas Instruments.

Q: Are the electrical specifications identical between CDCE706PWR and CDC706PW?

A: Yes. Both parts operate at identical maximum frequency (300MHz), supply voltage range (3V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and maintain the same PLL configuration with 1:6 input-to-output ratio.

Q: What is the difference in packaging between these parts?

A: CDCE706PWR is supplied in Tape & Reel (TR) configuration, standard for high-volume automated assembly. CDC706PW is supplied in Tube packaging, suitable for manual assembly or lower-volume applications. Both use the identical 20-TSSOP (0.173", 4.40mm Width) surface mount package form factor.

Q: Can I use CDC706PW for legacy system repairs?

A: Yes. CDC706PW is suitable for repair and replacement of existing systems where the original CDCE706PWR specification must be maintained. The electrical and mechanical equivalence ensures functional compatibility in established applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both CDCE706PWR and CDC706PW are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current environmental and reliability standards.

Q: What inventory considerations should I account for?

A: CDCE706PWR has significantly higher availability (35,200 units) compared to CDC706PW (652 units). For production applications, CDCE706PWR ensures reliable supply access. CDC706PW availability is limited and should not be relied upon for volume production.
