Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDC706PW is determined by strict equivalence across the following critical parameters:

• Package and Pinout: 20-TSSOP form factor with identical pin configuration
• Electrical Specifications: Maximum frequency of 300MHz, supply voltage range 3V to 3.6V, operating temperature -40°C to 85°C
• Functional Architecture: Single PLL circuit with bypass capability
• Signal Interface: LVCMOS and Crystal input support with LVCMOS output
• Input:Output Ratio: 1:6 frequency division/multiplication ratio
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The CDCE706PW qualifies as a parametric equivalent substitute based on complete alignment with all specified electrical, mechanical, and functional parameters.

Parameter Comparison

Engineering Selection Recommendations

The CDCE706PW represents a direct parametric equivalent to the CDC706PW across all specified electrical, mechanical, and functional criteria. Both devices maintain identical performance characteristics within the 300MHz frequency range, supply voltage specifications, and operating temperature envelope.

The primary distinction lies in product lifecycle status: the CDC706PW is designated "Not For New Designs," while the CDCE706PW maintains "Active" product status from Texas Instruments. For applications requiring ongoing component availability and manufacturer support, the CDCE706PW is the preferred selection. Both parts maintain equivalent ROHS3 compliance and MSL Level 1 ratings, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the CDCE706PW directly replace the CDC706PW in existing designs?

A: Yes. The CDCE706PW is a parametric equivalent with identical package, pinout, electrical specifications, and functional architecture. No circuit modifications are required for direct substitution.

Q: Are there any differences in supply voltage or operating temperature ranges?

A: No. Both parts operate across the identical 3V to 3.6V supply voltage range and -40°C to 85°C operating temperature range.

Q: Do both parts support the same input and output signal types?

A: Yes. Both the CDC706PW and CDCE706PW support LVCMOS and Crystal inputs with LVCMOS output configuration, maintaining the 1:6 input:output frequency ratio.

Q: What is the significance of the "Not For New Designs" status on the CDC706PW?

A: This designation indicates the CDC706PW has been superseded in Texas Instruments' product portfolio. While existing inventory remains available, the CDCE706PW is the recommended selection for new applications and ongoing production requirements.
