PI7C9X110BNB - 32-Bit 66MHz PCI Bridge | Diodes Inc
MPN: PI7C9X110BNB ✓ Hoạt độngPI7C9X110BNB Tóm tắt
A PCI-to-PCI bridge is an interface semiconductor used to connect otherwise incompatible expansion buses. Within the hierarchy of interface ICs, bus bridges convert protocol, signaling, and transaction formats so that legacy PCI equipment can operate through a PCIe host system. This makes the PI7C9X110BNB relevant to industrial computers, embedded systems, test equipment, and legacy peripheral adapters that require PCI compatibility.
The verified source information identifies the device as a 32-bit, 66 MHz PCI bridge with a reversible, non-transparent PCIe-to-PCI architecture. Its 160-LFBGA package provides a compact surface-mount implementation for multilayer PCB layouts. The 12 mm by 12 mm body and high pin count make controlled escape routing, uninterrupted power distribution, and careful thermal design essential during implementation.
Because this is a high-speed bus bridge, signal integrity strongly influences system performance. Differential PCIe routing and clock distribution require a continuous reference plane, controlled impedance, minimized stub lengths, and appropriately placed termination and decoupling networks. The supplied source material confirms the bridge's bus width, operating frequency, architecture, and package, but it does not provide verified voltage values, pin assignments, power ratings, or complete timing tables.
Typical use cases include PCI industrial controllers, embedded motherboard designs, data-acquisition systems, communications equipment, and legacy PCI expansion systems. The reversible bridge function can simplify system architecture when equipment must accommodate both PCIe hosts and PCI devices without maintaining separate processor interfaces. Its 66 MHz maximum PCI operating frequency supports legacy 32-bit PCI hardware in systems where higher-speed conversion is not required.
Designers should begin with the manufacturer datasheet and device pinout rather than inferring BGA connectivity from the distributor listings. The BGA footprint requires appropriate escape routing, via structures, solder-mask and paste patterns, and thermal verification. Power and ground distribution must be designed around the device's verified supply requirements once those values are obtained from the datasheet.
This page consolidates verified distributor and manufacturer information, distinguishes the PI7C9X110BNB from unverified functional equivalents, and adds package-aware replacement, comparison, and design guidance. It also identifies missing electrical and pin-level data explicitly so procurement and engineering decisions can proceed without fabricated specifications.

Ứng dụng tiêu biểu
PI7C9X110BNB phù hợp cho 6 Áp dụngs: Legacy PCI Expansion Systems, Industrial Data-Acquisition Equipment, Embedded Motherboards, Test and Measurement Instruments, Communications Equipment, Legacy Peripheral Test Platforms.
Legacy PCI Expansion Systems
The PI7C9X110BNB can provide the bridge path between a PCI Express host and a legacy 32-bit PCI expansion device. Its verified 66 MHz operating frequency and non-transparent reversible architecture are appropriate for systems that must preserve access to established PCI cards rather than redesign the equipment around a newer peripheral interface. In this arrangement, the host communicates through PCIe while the bridge translates transactions for the PCI-side device. Integration requires exact clock, reset, power, and signal-reference connections from the official datasheet. The 160-LFBGA footprint also requires multilayer escape routing and validation of the high-speed PCIe links before production release.
Được đề xuất
Industrial Data-Acquisition Equipment
Industrial data-acquisition equipment can use the PI7C9X110BNB when a modern PCIe controller must interoperate with a 32-bit PCI measurement card. The bridge's documented 66 MHz PCI capability supports legacy acquisition hardware while the reversible architecture can make cabling and bus-direction planning more flexible. The device is placed between the host's PCIe interface and the PCI peripheral, with power, clock, reset, and transaction-routing behavior configured according to the manufacturer reference design. Engineers must verify signal integrity, bus termination, isolation requirements, and the operating-temperature limits before using the bridge in factory-floor equipment.
Được đề xuất
Embedded Motherboards
Embedded motherboards can retain a legacy PCI connector by placing the PI7C9X110BNB between the processor's PCI Express interface and the conventional PCI bus. The verified 32-bit, 66 MHz bridge specification targets exactly this type of platform bridging, while the 12 mm by 12 mm LFBGA package supports compact board construction. A successful layout requires a solid reference plane, short BGA escape paths, controlled impedance, and power planes capable of meeting the final supply requirements. Because the supplied sources do not confirm operating-temperature range or power limits, these must be established from the datasheet before selecting the part for deployed industrial computers.
Được đề xuất
Test and Measurement Instruments
The PI7C9X110BNB is applicable to test and measurement instruments that retain PCI-based acquisition or modular instrumentation cards while exposing a PCIe host connection. Its 66 MHz, 32-bit PCI bridge capability allows supported legacy modules to operate behind a reversible PCIe-to-PCI conversion layer. In an instrument chassis, clock distribution and termination must be designed to prevent bus errors, while the BGA footprint should be reviewed for warpage, assembly yield, and service accessibility. The official datasheet and reference design should be checked for support of the exact PCI electrical load, reset behavior, and operating environment.
Được đề xuất
Communications Equipment
Communications equipment with retired PCI cards can use the PI7C9X110BNB to bridge those modules to a PCIe-based controller. The non-transparent bridge provides transaction conversion between the two bus domains, supporting equipment migration without immediately replacing every legacy module. The design remains sensitive to clock skew, trace impedance, return paths, and power-supply noise, especially across the many nets required by a 160-ball BGA. Use the manufacturer's recommended PCB layer stack and reference layout, and verify that the legacy card's bus-loading and timing requirements are supported by the specific PI7C9X110 configuration.
Được đề xuất
Legacy Peripheral Test Platforms
A PCI-to-PCIe test platform can place the PI7C9X110BNB at the boundary between modern automated test equipment and legacy PCI cards. The verified 66 MHz maximum frequency and reversible bridge behavior make the device relevant to controller development, compatibility testing, and factory test fixtures. Engineers should account for the bridge's undocumented-from-snippets electrical characteristics, including supply rails, I/O levels, input capacitance, and power consumption. The fixture also needs a continuous ground reference and carefully length-matched high-speed routes. No substitution should be approved unless its complete BGA pinout and bridge behavior have been compared against the manufacturer datasheet.

Ghi chú thiết kế
Implement the PI7C9X110BNB on a multilayer PCB using the manufacturer's reference stack-up and footprint. Maintain a continuous ground plane beneath the 160-LFBGA, route high-speed differential signals over controlled-impedance layers, and minimize BGA escape-routing length. The supplied Datasheet Archive summary specifically recommends minimizing signal-trace lengths and separating input and output signals to reduce noise.
Do not assign supply rails or capacitor values until they are confirmed from the manufacturer datasheet. Once known, provide separate low-impedance connections for each required voltage domain, place bulk capacitance near the device, and use multiple nearby decoupling connections to limit package and via inductance. Validate the PDN with the worst-case PCI traffic and bridge enable or reset transitions rather than relying only on quiescent-current calculations.
Treat the PCIe and PCI interfaces as controlled-impedance high-speed links. Use the datasheet's prescribed topology for clock distribution, serialization, termination, and reference connections; avoid adding stubs or test pads without accounting for their parasitics. Simulation should include connector and card loading, package parasitics, and board tolerances because these details are not available in the supplied search snippets.
Do not infer a 160-ball pinout from a generic BGA drawing or substitute PI7C9X110BNBE solely because both listings show the same package. Compare every ball name, supply rail, NC position, test point, and footprint dimension against the official documentation. Also verify lifecycle and temperature qualifications before using a substitute in a long-lifecycle industrial or medical system.
