PI7C8148BNJE - 32-Bit PCI-to-PCI Bridge | Diodes Incorporated
部品番号: PI7C8148BNJE ✓ 生産中PI7C8148BNJE 概要
A PCI bridge is a type of interface controller that connects two PCI bus domains while preserving the electrical and protocol behavior expected by PCI peripherals. The PI7C8148BNJE is intended for embedded systems, industrial equipment, communications platforms, and test systems that require a dedicated bridge rather than a direct connection between PCI devices. Its 32-bit bus width and 66 MHz operating frequency match the PCI bus-generation requirements identified in the verified product data.
The principal electrical characteristics available from the verified sources are a 3.3 V operating supply, a 3 V to 3.6 V supply-voltage range, and a 0 °C to 85 °C commercial operating-temperature range. The 160-LFBGA package provides a compact surface-mount implementation for space-constrained board designs. The verified distributor descriptions identify the part as a two-port PCI-to-PCI bridge interface, while the available technical listing identifies it as a 32-bit, 66 MHz PCI bridge chip.
Because the product data does not include a complete manufacturer electrical table, detailed specifications such as absolute maximum ratings, quiescent current, propagation delay, PCI signal-level thresholds, and package thermal resistance are recorded as data-needed rather than estimated. The available data also identifies the part as active in one distributor listing and confirms distribution through multiple channels, including DigiKey, Mouser, LCSC, and Octopart. Price and lead-time information should therefore be checked against the current distributor offer for the exact MPN.
Typical application considerations include host-adapter boards, embedded PCI expansion systems, industrial control equipment, and PCI-compatible communication or test platforms. The key design issue is ensuring that the bridge, power supply, clocking, and downstream PCI devices comply with the system’s PCI timing, impedance, and power-budget requirements. A compact 160-LFBGA footprint also demands careful PCB layout, thermal analysis, and assembly-process control.
This page combines the verified supplier specifications, package and pricing references, cross-reference candidates, and practical engineering considerations to provide a concise purchasing and design reference for the PI7C8148BNJE.

主な用途
PI7C8148BNJE の用途: 6 件s: PCI Expansion Adapter, Industrial PCI Control System, Communications Equipment, Embedded Test Platform, Data Acquisition Controller, Legacy PCI Storage Bridge.
PCI Expansion Adapter
PI7C8148BNJE is suitable for a PCI expansion adapter that must connect a host bus segment to downstream 32-bit PCI peripherals. Its verified 32-bit width, 66 MHz operating frequency, and two-port bridge function match the key topology of a dedicated PCI-to-PCI interface. The 160-LFBGA (15x15 mm) package also supports compact adapter boards. Before layout release, engineers should verify the complete ball assignment, PCI reference-clock requirements, and local decoupling values against the manufacturer datasheet. Board routing must preserve controlled impedance and provide a continuous ground reference for high-speed bus signals.
おすすめ
Industrial PCI Control System
PI7C8148BNJE can support a commercial-temperature industrial PCI control system requiring a bridged bus topology. Its stated 0 °C to 85 °C operating range covers many indoor industrial environments, while the 3.3 V supply operation supports integration with conventional embedded PCI hardware. The bridge should be placed where its 160-LFBGA lands can connect to short, impedance-controlled traces without excessive vias. System qualification should account for enclosure temperature, power-supply tolerance, PCI timing margins, and long-term availability.
おすすめ
Communications Equipment
PI7C8148BNJE is applicable to communications equipment that uses a PCI bus as an internal expansion interface. The two-port PCI-to-PCI arrangement allows a system architect to isolate a downstream device segment from the primary bus while retaining 32-bit, 66 MHz signaling. This can simplify topology in supervisory, protocol-conversion, or data-acquisition equipment. Because the verified data does not expose latency, arbitration, or clocking details, those parameters must be confirmed from the manufacturer datasheet. Signal-integrity simulation and PCI compliance testing are recommended before deployment.
おすすめ
Embedded Test Platform
PI7C8148BNJE can be incorporated into an embedded test platform that needs to connect two PCI domains for legacy peripheral testing. The verified 32-bit and 66 MHz characteristics align with a conventional PCI test fixture, while the compact surface-mount package leaves board area for instrumentation and interface circuitry. Engineers should verify reset, interrupt, clock, and power-state behavior in the manufacturer documentation. Test-platform layouts should include accessible probe points, careful termination, and a defined isolation strategy so faults in the downstream segment do not disrupt the host bus.
おすすめ
Data Acquisition Controller
PI7C8148BNJE is a candidate for data-acquisition controllers that combine a host interface with PCI-based analog or digital modules. Bridging the acquisition segment can reduce contention on the primary PCI bus and create a clearer separation between controller logic and measurement peripherals. The verified 3.3 V operating supply and commercial temperature range are useful baseline constraints for conventional laboratory equipment. Confirm timing margin, bus-master or subordinate behavior, and power requirements from the complete datasheet. Layout review should focus on return paths, clock distribution, and avoiding long stubs between the bridge and acquisition modules.
おすすめ
Legacy PCI Storage Bridge
PI7C8148BNJE may be used in legacy PCI storage systems where a secondary PCI segment connects storage or cache modules. Its two-port bridge arrangement permits the downstream storage segment to operate behind the bridge, while the verified 32-bit, 66 MHz PCI operation targets conventional parallel PCI infrastructure. The compact 160-LFBGA footprint helps maintain a small bridge section within a larger adapter. Design validation should include signal-integrity analysis, power-budget calculation, hot-plug or reset assumptions, and compatibility testing with every downstream PCI device and cable.

設計ノート
Route the PCI signals as controlled-impedance, point-to-point connections on a multilayer PCB and keep the 160-LFBGA escape paths as short as practical. Maintain a continuous ground reference beneath the device and the PCI routing region to limit return-path discontinuities. Verify every ball assignment, including power, ground, reference-clock, and configuration signals, against the manufacturer pinout before releasing fabrication files.
Design the 3.3 V rail for the bridge and all PCI-connected circuitry with the voltage tolerance required by the verified 3 V to 3.6 V operating range. Place local decoupling close to the supply and ground balls, and follow the manufacturer guidance for capacitor type, voltage rating, and quantity. Confirm the actual rail current, ripple, sequencing, and startup behavior with the complete electrical specification rather than relying on the nominal 3.3 V label.
Do not treat a cross-reference listing as proof that a replacement is pin-to-pin compatible. PI7C8148BNJ, PCI2060GHK, and TSI350-66CQY are identified as alternatives, but the supplied results do not provide complete ball maps or timing tables. Compare package drawings, power pins, clock inputs, reset behavior, interrupt routing, arbitration signals, and operating-temperature limits before approving any substitution for production.
Evaluate the 160-LFBGA footprint as part of the complete board thermal design, including copper area, adjacent component heat sources, airflow, and enclosure temperature. The verified operating range extends to 85 °C, where reduced thermal margin can affect system reliability. Use the manufacturer package data and a board-level thermal estimate during design review, especially when the bridge is positioned near switching regulators or dense I/O devices.
コンプライアンス情報
The verified data identifies a GREEN package and an active lifecycle status but does not explicitly state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 status. Compliance fields remain unknown rather than inferred.
