Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI6C10810HEX is determined by the following critical parameters:

• Functional Type: Fanout Buffer (Distribution) IC for clock distribution applications
• Input:Output Ratio: 1:10 configuration for single input to ten output distribution
• Maximum Frequency: 250 MHz operational capability
• Supply Voltage Range: 1.1V to 2.7V compatibility
• Package Compatibility: Surface mount form factor suitable for PCB integration
• Environmental Compliance: RoHS3 compliance and operating temperature range of -40°C to 85°C

The substitute part PI6C49X0210ZHIEX operates as a Fanout Buffer with different electrical specifications. While it maintains the same functional category and environmental compliance, it presents trade-offs in frequency capability, supply voltage range, and package form factor that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The PI6C49X0210ZHIEX is an active product from the same manufacturer, providing continued design support and supply chain availability. Both parts maintain ROHS3 compliance and identical operating temperature ranges, ensuring regulatory and environmental consistency.

Selection between these parts depends on application-specific requirements:

• Frequency Requirements: The PI6C10810HEX supports 250 MHz operation, while the PI6C49X0210ZHIEX is rated to 200 MHz. Applications requiring frequencies above 200 MHz cannot use the substitute.

• Supply Voltage Compatibility: The PI6C10810HEX operates from 1.1V to 2.7V, whereas the PI6C49X0210ZHIEX requires 2.375V to 3.465V. Systems with supply voltages below 2.375V cannot accommodate the substitute.

• Input Configuration: The PI6C49X0210ZHIEX accepts differential inputs and crystal inputs in addition to LVCMOS and LVTTL, providing greater input flexibility.

• Package Footprint: The PI6C10810HEX uses a 20-SSOP package, while the substitute employs a 32-VFQFN package. PCB layout and routing constraints must be evaluated for compatibility.

• Output Ratio: The PI6C10810HEX provides 1:10 distribution; the substitute offers 3:10 configuration, affecting the number of available output channels.

Frequently Asked Questions (FAQ)

Q: Can the PI6C49X0210ZHIEX directly replace the PI6C10810HEX on existing PCBs?

A: No. The packages differ significantly (20-SSOP versus 32-VFQFN), requiring PCB redesign. Additionally, the supply voltage ranges do not overlap completely, and the input:output ratios differ.

Q: What is the primary limitation when considering the PI6C49X0210ZHIEX as a substitute?

A: The maximum frequency rating of 200 MHz is lower than the PI6C10810HEX's 250 MHz capability. Applications operating above 200 MHz cannot use this substitute.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Yes. Both the PI6C10810HEX and PI6C49X0210ZHIEX are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Why does the PI6C49X0210ZHIEX have a higher supply voltage minimum?

A: The PI6C49X0210ZHIEX operates at 2.375V to 3.465V, which is typical for devices with differential input capability and enhanced signal processing features. The PI6C10810HEX's lower voltage range (1.1V to 2.7V) reflects its simpler single-ended input architecture.

Q: What are the key electrical parameters that determine substitutability?

A: Substitutability is determined by maximum frequency, supply voltage range, input:output ratio, input signal type compatibility, and output signal type. All must align with application requirements.

Q: Is the PI6C49X0210ZHIEX suitable for low-voltage applications below 2.375V?

A: No. The minimum supply voltage for the PI6C49X0210ZHIEX is 2.375V. Applications requiring operation below this voltage must use the PI6C10810HEX or identify alternative parts with lower voltage specifications.
