PI90LV048ALEX Equivalent & Substitute Parts

Part Overview

The PI90LV048ALEX is an LVDS receiver interface IC manufactured by Diodes Incorporated, configured as a 0/4 receiver in a 16-TSSOP surface mount package. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design support and procurement continuity. The part operates within the 3V to 3.6V supply range and supports 500 Mbps data rates across the -40°C to 85°C operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI90LV048ALEX is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Protocol: LVDS
• Configuration: 0/4 (0 Drivers, 4 Receivers)
• Package Type: 16-TSSOP
• Supply Voltage Range: 3V to 3.6V
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Consideration Parameters:

• Data Rate: 500 Mbps (primary part specification; substitutes may operate at 200 Mbps to 500 Mbps within the same protocol)
• Operating Temperature: -40°C to 85°C (primary part specification; substitutes at 0°C to 70°C represent a narrower range)

All identified substitute parts maintain identical package geometry, supply voltage specifications, and RoHS compliance status. Variations in data rate and operating temperature range are noted where they differ from the primary part.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MAX9122EUE+

The MAX9122EUE+ from Analog Devices Inc./Maxim Integrated provides the closest functional equivalence to the PI90LV048ALEX. This part maintains identical electrical specifications (500 Mbps data rate, 3V to 3.6V supply, -40°C to 85°C operating range) and package geometry (16-TSSOP). The part is in active production status with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and regulatory compliance.

Secondary Recommendations: SN65LVDS048APW and SN65LVDS048APWR

Texas Instruments SN65LVDS048 series parts (APW and APWR variants) provide functional substitution with a reduced data rate specification of 400 Mbps. These parts maintain the full -40°C to 85°C operating temperature range and identical supply voltage specifications. Both variants are in active production with ROHS3 compliance. The APW variant is supplied in tube packaging, while the APWR variant is supplied in cut tape and digi-reel format.

Alternative Recommendations: SN65LVDS390 and SN75LVDS390 Series

The SN65LVDS390 and SN75LVDS390 series parts operate at 200 Mbps data rate. SN65LVDS390 variants (PW and PWR) maintain the full -40°C to 85°C operating temperature range. SN75LVDS390 variants (PW and PWR) operate within a narrower 0°C to 70°C temperature range. All variants are in active production with ROHS3 compliance. These parts are suitable for applications where the reduced data rate specification is acceptable.

Temperature Range Consideration:

Applications requiring operation below 0°C or above 70°C must select from parts maintaining the -40°C to 85°C specification: MAX9122EUE+, SN65LVDS048APW, SN65LVDS048APWR, SN65LVDS390PW, SN65LVDS390PWR, or SN65LVDT390PWR.

Frequently Asked Questions (FAQ)

Q: Can the MAX9122EUE+ directly replace the PI90LV048ALEX?

A: Yes. The MAX9122EUE+ maintains identical electrical specifications (500 Mbps, 3V to 3.6V, -40°C to 85°C) and package type (16-TSSOP). Pin-level compatibility must be confirmed through datasheet review, but the functional parameters are equivalent.

Q: What is the difference between SN65LVDS048APW and SN65LVDS048APWR?

A: Both parts are functionally identical with 400 Mbps data rate and -40°C to 85°C operating range. The primary difference is packaging format: APW is supplied in tube packaging, while APWR is supplied in cut tape and digi-reel format. Selection depends on procurement and assembly requirements.

Q: Why do some substitute parts specify 200 Mbps instead of 500 Mbps?

A: The SN65LVDS390, SN75LVDS390, and SN65LVDT390 series are designed for lower data rate applications. These parts maintain LVDS protocol compliance and identical package geometry but operate at reduced bandwidth. They are suitable for applications where 200 Mbps data rate meets system requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification and MSL 1 (unlimited) moisture sensitivity rating, matching the original PI90LV048ALEX specifications.

Q: What is the impact of the narrower operating temperature range in SN75LVDS390 parts?

A: SN75LVDS390 variants (PW and PWR) operate within 0°C to 70°C, compared to the -40°C to 85°C range of the original part. These parts are unsuitable for applications requiring operation below 0°C or above 70°C. For full temperature range coverage, select from MAX9122EUE+, SN65LVDS048, or SN65LVDS390/SN65LVDT390 series.

Q: Is the SN65LVDT390PWR equivalent to SN65LVDS390PWR?

A: Both parts maintain identical electrical specifications (200 Mbps, 3V to 3.6V, -40°C to 85°C) and package type (16-TSSOP). The functional parameters are equivalent. The designation difference (LVDT vs. LVDS) reflects internal architecture variations that do not affect substitution eligibility for this application category.
