CDC906PWR PLL Frequency Synthesizer Equivalent & Substitute Parts

Part Overview

The CDC906PWR is a PLL Frequency Synthesizer IC manufactured by Texas Instruments, designed for clock and timing applications requiring frequency synthesis up to 167MHz. This device integrates a phase-locked loop with bypass capability, supporting both LVCMOS and crystal inputs with LVCMOS output configuration.

The CDC906PWR carries a "Not For New Designs" product status, indicating it has been superseded in Texas Instruments' product portfolio. Identifying equivalent substitute parts is necessary for ongoing production support, maintenance applications, and legacy system requirements where this specific device remains specified.

Substitute Part Grouping Explanation

Substitution eligibility for the CDC906PWR is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Texas Instruments
• Device Type: PLL Frequency Synthesizer with Bypass capability
• Maximum Operating Frequency: 167MHz
• Input Configuration: LVCMOS and Crystal support
• Output Configuration: LVCMOS
• Input:Output Ratio: 1:6
• Supply Voltage Range: 3V ~ 3.6V
• Operating Temperature Range: 0°C ~ 70°C
• Package: 20-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount

The CDCE906PWR meets all mandatory matching parameters and qualifies as a parametric equivalent. Both devices share identical electrical specifications, functional architecture, and physical packaging, enabling direct substitution in applications where the CDC906PWR is currently specified.

Parameter Comparison

Engineering Selection Recommendations

The CDCE906PWR is the direct parametric equivalent for CDC906PWR applications. Both devices are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The CDC906PWR is designated "Not For New Designs," while the CDCE906PWR maintains Active product status. This status difference reflects Texas Instruments' current product support posture and does not indicate functional or electrical differences between the devices.

Compliance and Certification: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels, ensuring equivalent environmental and regulatory compliance for applications requiring these certifications.

Packaging and Availability: The CDCE906PWR is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexible procurement options for production environments. The CDC906PWR original packaging format (Tape & Reel) remains available through existing inventory channels.

Frequently Asked Questions (FAQ)

Q: Can CDCE906PWR be used as a direct replacement for CDC906PWR in existing designs?

A: Yes. The CDCE906PWR is a parametric equivalent with identical electrical specifications, functional architecture, and 20-TSSOP package configuration. Direct substitution is supported without circuit modification.

Q: What is the significance of the "Not For New Designs" status on CDC906PWR?

A: This designation indicates the CDC906PWR has been superseded in Texas Instruments' active product portfolio. The CDCE906PWR represents the current active equivalent. For new designs, CDCE906PWR is the recommended selection. For legacy system support, CDC906PWR remains functionally equivalent.

Q: Are the pin configurations identical between CDC906PWR and CDCE906PWR?

A: Both devices use the 20-TSSOP package with identical physical dimensions (0.173", 4.40mm Width). Pin configuration compatibility is maintained for direct board-level substitution.

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

A: Yes. Both CDC906PWR and CDCE906PWR support LVCMOS and crystal inputs with LVCMOS output configuration, maintaining identical signal interface compatibility.

Q: What are the packaging format differences between the two parts?

A: CDC906PWR is supplied in Tape & Reel (TR) format. CDCE906PWR is available in Cut Tape (CT) and Digi-Reel® formats. These are packaging and distribution format differences only; the devices themselves are electrically and mechanically identical.

Q: Are there any supply voltage or temperature range differences?

A: No. Both parts operate across the identical 3V ~ 3.6V supply voltage range and 0°C ~ 70°C operating temperature range.

Q: Which part should be selected for new production designs?

A: CDCE906PWR should be selected for new designs due to its Active product status and equivalent performance specifications. CDC906PWR remains available for legacy system support and maintenance applications.
