Key Parameters

Substitute Part Grouping Explanation

The CDCE706PWRG4 can be substituted with the CDCE706PWR based on strict parametric equivalence. Both parts share identical electrical and functional specifications:

Key Parameters Determining Substitution:

• Identical base product number (CDCE706)
• Same package type: 20-TSSOP (0.173", 4.40mm Width)
• Matching frequency specification: 300MHz maximum
• Identical supply voltage range: 3V ~ 3.6V
• Same operating temperature range: -40°C ~ 85°C
• Identical PLL configuration with bypass capability
• Matching input/output signal types: LVCMOS and Crystal input, LVCMOS output
• Same circuit count and input:output ratio (1:6)
• Identical divider/multiplier functionality

The primary difference between these parts is packaging format and product status. The CDCE706PWRG4 is supplied in tube packaging and is discontinued, while the CDCE706PWR is supplied in Tape & Reel (TR) format and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The CDCE706PWR is the direct parametric equivalent for the CDCE706PWRG4 and is suitable for substitution in all applications where the original part was specified. Selection between these parts should be based on the following criteria:

For New Designs or Restocking: Select CDCE706PWR. This part maintains active product status with Texas Instruments, ensuring long-term availability and supply chain stability. The Tape & Reel packaging format is standard for automated assembly processes and high-volume production environments.

For Existing Inventory or Legacy Systems: The CDCE706PWRG4 remains functionally equivalent and maintains full compliance with ROHS3 and REACH requirements. Current inventory of 1183 units is available for immediate deployment in applications requiring this specific packaging format.

Compliance Considerations: Both parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for industrial and commercial applications. Moisture Sensitivity Level 1 (Unlimited) indicates no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can CDCE706PWR be used as a direct replacement for CDCE706PWRG4 in existing circuit designs?

A: Yes. Both parts are electrically and functionally identical. The only difference is packaging format (Tape & Reel versus tube). No circuit modifications or design changes are required for substitution.

Q: What is the significance of the packaging format difference between these parts?

A: CDCE706PWRG4 uses tube packaging, typically for manual assembly or lower-volume applications. CDCE706PWR uses Tape & Reel (TR) format, which is standard for automated pick-and-place assembly equipment. The choice depends on your manufacturing process and assembly volume requirements.

Q: Are there any electrical performance differences between CDCE706PWRG4 and CDCE706PWR?

A: No. Both parts share identical electrical specifications, including frequency range (300MHz maximum), supply voltage (3V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and all functional parameters.

Q: Why is CDCE706PWRG4 discontinued while CDCE706PWR remains active?

A: Product discontinuation typically reflects market demand and manufacturing priorities. The CDCE706PWR in Tape & Reel format aligns with modern automated assembly practices and remains the active product offering from Texas Instruments.

Q: Do both parts require the same PCB footprint and layout considerations?

A: Yes. Both parts use the identical 20-TSSOP package with 0.173" width and 4.40mm dimensions. PCB footprints, trace routing, and layout designs are fully compatible between these parts.

Q: What is the Moisture Sensitivity Level (MSL) rating, and does it affect handling?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity. These parts do not require special dry-pack storage, desiccant handling, or bake-out procedures prior to assembly.
