830154AMI-08LF Clock Fanout Buffer Equivalent & Substitute Parts

Part Overview

The 830154AMI-08LF is a Clock Fanout Buffer (Distribution) IC manufactured by Renesas Electronics Corporation, designed for 1:4 clock distribution at frequencies up to 160 MHz. This device features LVCMOS input and output signaling, operates across a supply voltage range of 1.4V to 3.465V, and is housed in an 8-SOIC package.

The 830154AMI-08LF is classified as Obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this original part is no longer readily procurable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 830154AMI-08LF is determined by the following critical parameters:

Mandatory Matching Parameters:

• Ratio - Input:Output: 1:4
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Input Signal Type: LVCMOS
• Output Signal Type: LVCMOS
• Operating Temperature Range: -40°C ~ 85°C
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Frequency - Max: Equal to or greater than 160 MHz
• Voltage - Supply: Must encompass or be compatible with 1.4V ~ 3.465V range

Two substitute parts meet these criteria:

PI6C10804WE (Diodes Incorporated) — MFR Recommended Substitute: Matches all mandatory parameters with maximum frequency of 180 MHz and supply voltage range of 1.4V ~ 2.7V. The narrower supply voltage range (2.7V upper limit versus 3.465V) represents a constraint that must be evaluated against specific application requirements.

NB3U1548CDG (onsemi) — Parametric Equivalent: Provides identical electrical specifications to the original part, including 160 MHz maximum frequency and 1.4V ~ 3.465V supply voltage range, with Active product status.

Parameter Comparison

Engineering Selection Recommendations

NB3U1548CDG (onsemi) is the primary parametric equivalent for direct replacement of the 830154AMI-08LF. This part maintains identical electrical specifications, including maximum frequency and supply voltage range, and carries Active product status, ensuring long-term availability and supply chain stability. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are equivalent.

PI6C10804WE (Diodes Incorporated) serves as an alternative with enhanced frequency capability (180 MHz versus 160 MHz). However, the reduced maximum supply voltage (2.7V upper limit) requires evaluation against application-specific power supply specifications. This part is classified as Discontinued at DiGi Electronics, which may impact long-term procurement. The expanded input/output signal compatibility (LVCMOS and LVTTL) provides additional flexibility in mixed-signal environments.

Selection between these substitutes depends on supply voltage requirements and long-term component availability needs. For applications operating at supply voltages above 2.7V, NB3U1548CDG is the appropriate choice. For applications within the 1.4V to 2.7V range where higher frequency margin is beneficial, PI6C10804WE is suitable.

Frequently Asked Questions (FAQ)

Q: Can PI6C10804WE be used in applications requiring supply voltages above 2.7V?

A: No. PI6C10804WE is specified for 1.4V ~ 2.7V supply voltage. Applications requiring operation at 3.0V or 3.3V must use NB3U1548CDG, which supports 1.4V ~ 3.465V.

Q: What is the significance of the 1:4 ratio specification?

A: The 1:4 ratio indicates that the device accepts one clock input signal and distributes it to four independent output channels. All substitute parts maintain this same distribution ratio.

Q: Are the 8-SOIC packages physically identical across all three parts?

A: Yes. All three parts use the 8-SOIC (0.154", 3.90mm Width) package with identical pin assignments and footprints, enabling direct PCB-level substitution without layout modifications.

Q: Does the higher frequency rating of PI6C10804WE (180 MHz) provide any advantage over the 160 MHz rating of NB3U1548CDG?

A: The higher frequency rating provides additional operational margin for applications operating at or near 160 MHz. However, if the application clock frequency does not exceed 160 MHz, both parts perform identically at the operating frequency.

Q: What is the impact of LVTTL compatibility in PI6C10804WE?

A: PI6C10804WE accepts both LVCMOS and LVTTL input signals, while NB3U1548CDG accepts LVCMOS only. In systems using LVTTL clock sources, PI6C10804WE provides direct compatibility without additional signal conditioning.

Q: Are all three parts RoHS compliant?

A: Yes. The 830154AMI-08LF, PI6C10804WE, and NB3U1548CDG are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and reliability standards.

Q: What is the difference between "Obsolete" and "Discontinued at DiGi Electronics" product status?

A: Obsolete indicates the manufacturer has ceased production. Discontinued at DiGi Electronics indicates the distributor no longer stocks the part, though limited inventory may exist through alternative channels. Active status (NB3U1548CDG) indicates ongoing manufacturer production and distributor availability.
