• Identical supply voltage range: 3V ~ 3.6V
• Matching operating temperature range: -40°C ~ 85°C
• Identical package specification: 64-WQFN (5.5x10) with exposed pad
• Matching differential input/output configuration
• Identical moisture sensitivity level: MSL 2 (1 Year)
• Identical compliance classification: EAR99 / HTSUS 8542.39.0001

Both parts are manufactured by Texas Instruments and maintain Active product status, ensuring continued manufacturing support and availability.

Parameter Comparison

Engineering Selection Recommendations

Both DS320PR822NJXT and DS320PR822NJXR are qualified substitutes for PCIe 5.0 interface applications requiring 32 Gbps buffer redrive functionality. Selection between these parts is based on the following engineering considerations:

Product Status & Support: Both parts maintain Active manufacturing status from Texas Instruments, ensuring continued availability and technical support throughout the product lifecycle.

Compliance & Regulatory: Both parts carry identical compliance classifications (EAR99 export control, HTSUS 8542.39.0001 tariff code) and equivalent RoHS status designation. No regulatory or compliance barriers exist for substitution.

Inventory Availability: DS320PR822NJXR currently maintains higher inventory levels (3901 units) compared to DS320PR822NJXT (902 units), making it suitable for applications with extended lead time requirements or high-volume production schedules.

Electrical & Mechanical Equivalence: Complete parameter equivalence across all specified electrical characteristics (data rate, channel configuration, delay time, input capacitance, supply voltage, operating temperature) and mechanical specifications (package type, pin count, form factor) ensures direct functional interchangeability without circuit redesign or board layout modification.

Moisture Handling: Both parts carry MSL 2 classification with 1-year floor life, requiring identical moisture control procedures during storage, handling, and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can DS320PR822NJXR be used as a direct replacement for DS320PR822NJXT in existing PCB designs?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. No circuit modifications, board layout changes, or firmware updates are required for substitution. The 64-WQFN (5.5x10) package footprint, pin assignment, and functional behavior are identical.

Q: What are the key parameters that determine substitution eligibility for this buffer reddriver?

A: Substitution eligibility is determined by equivalence in: data rate (32 Gbps), channel configuration (4 x 2:2), signal conditioning method (input equalization), delay time (0.1 ns), input capacitance (1.6 pF), supply voltage range (3V ~ 3.6V), operating temperature range (-40°C ~ 85°C), package type (64-WQFN with exposed pad), and compliance classifications (EAR99, HTSUS 8542.39.0001).

Q: Are there any differences in PCB assembly or soldering procedures between these two parts?

A: No. Both parts use identical Surface Mount technology with the same 64-WQFN (5.5x10) package specification, exposed pad configuration, and Tape & Reel (TR) packaging format. Assembly procedures, reflow profiles, and handling requirements are identical.

Q: What is the significance of the MSL 2 (1 Year) moisture sensitivity rating?

A: MSL 2 classification indicates the component requires moisture control during storage and handling. The 1-year floor life means the part can remain exposed to ambient conditions for up to one year before requiring baking. Both substitute parts carry identical MSL specifications, requiring equivalent moisture management protocols.

Q: How do the inventory levels affect component selection?

A: DS320PR822NJXR maintains significantly higher inventory (3901 units versus 902 units for DS320PR822NJXT). For applications with extended production schedules or high-volume requirements, DS320PR822NJXR may offer improved supply chain reliability and shorter procurement lead times.

Q: Are there any application-specific limitations for either substitute part?

A: No application-specific limitations exist between these parts. Both are qualified for PCIe 5.0 interface applications requiring differential input/output buffer redrive functionality with integrated input equalization across the full -40°C to 85°C operating temperature range.

Q: What compliance documentation is available for these parts?

A: Both parts carry EAR99 export control classification and HTSUS 8542.39.0001 tariff code designation. RoHS status is listed as Not applicable for both parts. Identical compliance profiles ensure no regulatory barriers to substitution.
