Key Parameters

Substitute Part Grouping Explanation

Substitution for the CDCE906PWG4 is determined by strict equivalence across the following critical parameters:

• Functional Type: PLL Frequency Synthesizer with identical circuit count (1)
• Frequency Performance: Maximum frequency of 167MHz
• Signal Interface: LVCMOS and Crystal input support with LVCMOS output
• Electrical Specifications: Supply voltage range 3V ~ 3.6V, operating temperature 0°C ~ 70°C
• Physical Package: 20-TSSOP form factor with identical dimensions (0.173", 4.40mm Width)
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The identified substitute parts maintain full electrical and mechanical compatibility with the original CDCE906PWG4 specification while differing in product status and availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CDCE906PW

The CDCE906PW is the manufacturer-recommended substitute for the CDCE906PWG4. This part maintains identical electrical and mechanical specifications while offering active product status and verified programmability. The CDCE906PW is supplied in Tube packaging and demonstrates full compatibility across all critical parameters. This part is the preferred selection for new procurement and design continuity.

Secondary Substitute: CDC906PW

The CDC906PW provides parametric equivalence with identical frequency synthesis capability, signal interface, and package configuration. However, this part carries a "Not For New Designs" status and lacks verified programmability certification. The CDC906PW is suitable only for legacy system maintenance or replacement applications where design validation has already been completed. This part should not be selected for new development initiatives.

Frequently Asked Questions (FAQ)

Q: Can CDCE906PW directly replace CDCE906PWG4 in existing designs?

A: Yes. The CDCE906PW maintains full electrical and mechanical compatibility with the CDCE906PWG4 across all specified parameters including frequency performance, signal interface, supply voltage, operating temperature range, and 20-TSSOP package dimensions.

Q: What is the difference between CDCE906PW and CDC906PW?

A: Both parts are parametrically equivalent in frequency synthesis capability and package configuration. The primary differences are product lifecycle status (CDCE906PW is Active; CDC906PW is Not For New Designs) and programmability verification (CDCE906PW is Verified; CDC906PW is Not Verified). For new applications, CDCE906PW is the appropriate selection.

Q: Are there packaging differences between the substitute parts?

A: The CDCE906PWG4 packaging format is not specified in the available data. Both substitute parts (CDCE906PW and CDC906PW) are supplied in Tube packaging. Confirm packaging requirements with your procurement specification before finalizing component selection.

Q: What compliance certifications apply to these substitute parts?

A: All three parts (CDCE906PWG4, CDCE906PW, and CDC906PW) maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) rating, ensuring compatibility with standard manufacturing and storage protocols.

Q: Is the 1:6 input-to-output ratio maintained across all substitute parts?

A: Yes. All three parts maintain the 1:6 input-to-output ratio specification, ensuring frequency synthesis behavior remains consistent across substitution.
