PCI2050BZHK

PCI2050BZHK Description

The PCI2050BZHK from Texas Instruments is a specialized interface IC designed for PCI (Peripheral Component Interconnect) bus applications, packaged in a 257-ball BGA (Ball Grid Array). Operating within a 3V to 3.6V supply voltage range, this surface-mount device is optimized for high-performance backplane connectivity. Though marked as obsolete, it remains relevant for legacy systems requiring ROHS3-compliant and REACH-unaffected components. With a Moisture Sensitivity Level (MSL) of 3 (168 hours), it ensures reliability in controlled environments. Its EAR99 classification indicates minimal export restrictions, facilitating global deployment.

PCI2050BZHK Features

• PCI Interface: Supports high-speed data transfer for backplane and embedded systems.
• Low-Voltage Operation: 3V–3.6V range enhances power efficiency in compact designs.
• Robust Packaging: 257-BGA ensures mechanical stability and thermal performance.
• Compliance: ROHS3 and REACH compliant, meeting environmental standards.
• Extended MSL Rating: MSL 3 (168 hours) allows for prolonged exposure during assembly.
• Legacy Support: Ideal for maintaining or upgrading older PCI-based systems.

PCI2050BZHK Applications

• Embedded Systems: Used in industrial PCs and control systems requiring PCI connectivity.
• Telecommunications: Backplane interconnects in legacy networking equipment.
• Medical Devices: Integration into diagnostic systems with PCI-based architecture.
• Military/Aerospace: Suitable for ruggedized applications due to its BGA reliability.
• Test & Measurement: Interface solutions for PCI-dependent instrumentation.

Conclusion of PCI2050BZHK

The PCI2050BZHK is a high-reliability, low-voltage PCI interface IC tailored for specialized backplane applications. While obsolete, its BGA packaging, compliance certifications, and legacy PCI support make it a pragmatic choice for maintaining older systems or niche designs. Engineers in industrial, telecom, and aerospace sectors will find it valuable for its balance of performance and durability. For modern designs, consider TI’s active alternatives, but for legacy compatibility, this IC remains a robust solution.
