Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI6C2408-1HLE is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 16-TSSOP (0.173", 4.40mm Width) surface mount package to ensure PCB layout compatibility without redesign.

Supply Voltage Range: The substitute must operate within the 3V to 3.6V supply voltage window to maintain compatibility with existing power distribution networks.

Logic Level Compatibility: Input and output logic levels must be compatible with TTL or LVTTL standards to ensure signal integrity with connected circuitry.

Frequency Performance: The substitute must support the maximum frequency requirements of the application. The PI6C2408-1HLE operates at 140MHz maximum; substitutes with equal or higher frequency ratings are acceptable.

PLL and Bypass Capability: The presence of PLL with bypass functionality is a key functional requirement for this device class.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status ensure regulatory alignment across manufacturing regions.

The CDCVF25084PW from Texas Instruments meets all substitution criteria while offering enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The CDCVF25084PW is the qualified substitute for the PI6C2408-1HLE based on the following engineering criteria:

Package Equivalence: Both devices use identical 16-TSSOP surface mount packaging, eliminating PCB layout modifications.

Electrical Compatibility: Supply voltage range (3V ~ 3.6V) and logic level standards (TTL/LVTTL) are compatible with existing system designs. The CDCVF25084PW operates at 180MHz, exceeding the 140MHz requirement of the original part.

Functional Capability: Both devices incorporate PLL with bypass functionality, maintaining the core timing and distribution capabilities required by the application.

Regulatory Status: The CDCVF25084PW holds active product status with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory alignment.

Temperature Range Enhancement: The substitute supports an extended operating temperature range (-40°C ~ 85°C) compared to the original part (0°C ~ 70°C), providing greater operational flexibility for demanding environments.

Multiplier Functionality: The CDCVF25084PW includes divider/multiplier capability (2:8 ratio), offering additional functional flexibility beyond the 1:8 fixed ratio of the original part.

Frequently Asked Questions (FAQ)

Q: Can the CDCVF25084PW directly replace the PI6C2408-1HLE without PCB modifications?

A: Yes. Both devices use the 16-TSSOP package with identical pin spacing and dimensions (0.173", 4.40mm Width). No PCB layout changes are required for package compatibility.

Q: Are the logic levels compatible between these devices?

A: Yes. The PI6C2408-1HLE uses TTL logic, and the CDCVF25084PW uses LVTTL logic. LVTTL is backward compatible with TTL input thresholds and produces TTL-compatible output levels within the 3V ~ 3.6V supply range.

Q: What is the frequency performance difference?

A: The PI6C2408-1HLE operates at a maximum of 140MHz, while the CDCVF25084PW supports 180MHz. The substitute exceeds the original part's frequency capability, making it suitable for applications requiring the original 140MHz performance.

Q: Does the input-to-output ratio difference affect substitution?

A: The PI6C2408-1HLE has a 1:8 ratio, while the CDCVF25084PW has a 2:8 ratio. The substitute's multiplier capability provides additional functional flexibility. System design must account for the different input-to-output relationship during implementation.

Q: What is the significance of the extended temperature range in the substitute?

A: The CDCVF25084PW operates from -40°C to 85°C, compared to the original part's 0°C to 70°C range. This extended range provides operational capability in wider environmental conditions, beneficial for industrial and automotive applications.

Q: Are both devices RoHS compliant?

A: Yes. Both the PI6C2408-1HLE and CDCVF25084PW are ROHS3 compliant with MSL rating 1 (Unlimited), meeting regulatory requirements for manufacturing and distribution across all regions.

Q: Why is the original part classified as obsolete?

A: The PI6C2408-1HLE is no longer in active production by Diodes Incorporated. The CDCVF25084PW from Texas Instruments is an active product with equivalent functionality and enhanced performance characteristics, making it the recommended substitute for new designs and ongoing system support.
