PI6C10810LEX Equivalent & Substitute Parts

Part Overview

The PI6C10810LEX is a Clock Fanout Buffer (Distribution) IC manufactured by Diodes Incorporated, designed for 1:10 clock distribution at frequencies up to 250 MHz. This component operates across a wide supply voltage range of 1.1V to 2.7V and supports LVCMOS and LVTTL input/output standards. The device is packaged in a 20-TSSOP surface mount package with a 0.173" width (4.40mm).

The PI6C10810LEX has reached Last Time Buy status, indicating end-of-life production. Identifying equivalent substitute parts is necessary to ensure continued design flexibility and supply chain continuity for new designs or production transitions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI6C10810LEX is constrained by the following critical parameters:

• Input:Output Ratio: The 1:10 distribution ratio is a primary functional requirement. Substitute parts must maintain equivalent or compatible clock distribution capability.
• Maximum Frequency: The 250 MHz specification defines the maximum clock speed the device can process. Substitutes operating at lower frequencies may be acceptable for designs not requiring full bandwidth.
• Supply Voltage Range: The 1.1V to 2.7V operating window is specific to low-voltage applications. Substitutes with different voltage requirements may necessitate circuit redesign.
• Input/Output Logic Standards: LVCMOS and LVTTL compatibility ensures signal integrity with standard digital logic families.
• Package and Mounting: Surface mount 20-TSSOP packaging is a physical constraint for PCB integration.

The PI6C49X0210ZHIEX is identified as a manufacturer-recommended substitute. This part operates as a 3:10 fanout buffer at 200 MHz maximum frequency with a different supply voltage range (2.375V to 3.465V) and package format (32-VFQFN). Substitution requires verification that the application can accommodate these parameter differences.

Engineering Selection Recommendations

PI6C10810LEX (Main Part)

The PI6C10810LEX is suitable for applications requiring low-voltage operation (1.1V to 2.7V) with 1:10 clock distribution at frequencies up to 250 MHz. This part is ROHS3 compliant and carries unlimited moisture sensitivity rating, indicating robust handling characteristics. However, Last Time Buy status indicates this part will no longer be manufactured, making it unsuitable for new designs requiring long-term supply availability.

PI6C49X0210ZHIEX (Substitute)

The PI6C49X0210ZHIEX is an active product from Diodes Incorporated with ongoing manufacturing support. It provides 3:10 clock distribution at 200 MHz maximum frequency. Key differences include:

• Higher supply voltage requirement (2.375V to 3.465V) versus the main part's 1.1V to 2.7V range
• Lower maximum frequency (200 MHz versus 250 MHz)
• Larger package footprint (32-VFQFN versus 20-TSSOP)
• Support for differential inputs and crystal oscillator inputs
• CMOS output standard (versus LVCMOS/LVTTL)

Selection of the PI6C49X0210ZHIEX requires confirmation that the application can operate within its specified voltage range, accept the reduced frequency ceiling, and accommodate the larger package dimensions. Both parts maintain ROHS3 compliance and unlimited MSL rating.

Frequently Asked Questions (FAQ)

Q: Can the PI6C49X0210ZHIEX directly replace the PI6C10810LEX on an existing PCB?

A: Direct PCB replacement is not possible due to package differences. The PI6C10810LEX uses a 20-TSSOP package, while the PI6C49X0210ZHIEX uses a 32-VFQFN package. PCB layout redesign is required. Additionally, the supply voltage range differs (1.1V–2.7V versus 2.375V–3.465V), requiring circuit modifications.

Q: What is the functional difference between 1:10 and 3:10 clock distribution ratios?

A: The 1:10 ratio (PI6C10810LEX) accepts one clock input and distributes it to 10 outputs. The 3:10 ratio (PI6C49X0210ZHIEX) accepts three clock inputs and distributes them to 10 outputs. Application requirements determine which ratio is appropriate.

Q: Does the 50 MHz frequency difference between these parts affect compatibility?

A: The PI6C10810LEX operates to 250 MHz, while the PI6C49X0210ZHIEX operates to 200 MHz. If the application requires clock frequencies above 200 MHz, the substitute part is not suitable. If the application operates below 200 MHz, the frequency difference is not a limiting factor.

Q: Are both parts RoHS compliant?

A: Yes, both the PI6C10810LEX and PI6C49X0210ZHIEX are ROHS3 compliant and carry unlimited MSL ratings.

Q: What supply voltage should be used with each part?

A: The PI6C10810LEX operates within 1.1V to 2.7V. The PI6C49X0210ZHIEX operates within 2.375V to 3.465V. The voltage ranges do not overlap below 2.375V, so applications using supply voltages below 2.375V cannot use the substitute part without circuit modification.
