PEX8712-CA80BC - 12-Lane PCIe Gen 3 Switch | Broadcom
MPN: PEX8712-CA80BC ✗ जीवन की समाप्तिPEX8712-CA80BC अवलोकन
A PCIe switch is an interface IC that sits between a host or root complex and multiple PCIe endpoints. It provides fan-out, non-blocking interconnection, and centralized switching for systems such as servers, storage equipment, communications platforms, and graphics systems. The PEX8712-CA80BC is intended for designs that require a wider PCIe lane count and multiple downstream connections while maintaining Gen 3 PCIe operation.
The verified product information identifies the device as a 12-lane, 3-port PCI Express Gen 3 switch. The Broadcom product page also specifies a typical power of 3.5 W and identifies the integrated package as a 19 x 19 mm, 324-pin FCBGA. These characteristics make the device suitable for board-level infrastructure where a compact, high-density switch implementation is required.
The target orderable designation PEX8712-CA80BC is associated with the Broadcom PEX 8712 family. The listings use the related notation PEX8712-CA80BC-G, while the requested product identifier is PEX8712-CA80BC. Package details, electrical limits, thermal resistance, reference clock requirements, lane-specific performance, and the complete pin assignment require confirmation from the manufacturer datasheet before schematic release.
Typical implementation involves routing the host-facing PCIe lanes, endpoint-facing lanes, auxiliary power, reference clock, control signals, and configuration interfaces through a dense multilayer PCB. Because the device is supplied in an FCBGA package, careful escape routing, via-in-pad or microvia strategy, reference-plane continuity, power delivery, and thermal management are essential. The 3.5 W typical power figure also makes power budget and junction-temperature calculations a central part of system validation.
For new designs, verify the exact ordering code, package ball map, electrical characteristics, firmware requirements, reference design, and supported platform configuration with Broadcom. For replacement evaluation, use the manufacturer cross-reference process or the Request a Quote form on this page to confirm availability and technical suitability rather than assuming that a different PCIe switch is pin-compatible.

सामान्य अनुप्रयोग
PEX8712-CA80BC के लिए उपयुक्त है 6 अनुप्रयोगs: Server PCIe Fan-Out, Storage Controller Expansion, Communications Infrastructure, Graphics and Acceleration Platform, Industrial PCIe Adapter, Multi-Host Test Platform.
Server PCIe Fan-Out
The PEX8712-CA80BC is appropriate for a server platform that needs to fan a PCIe Gen 3 host connection out to multiple endpoint devices. Its confirmed 12-lane, 3-port configuration provides a defined multi-host switching resource, while Broadcom identifies servers as a target application. The board must still validate lane bifurcation, endpoint mapping, clock distribution, and platform firmware. With typical power of 3.5 W, power delivery and package thermal paths should be planned during schematic and stack-up design rather than added after layout.
अनुशंसित
Storage Controller Expansion
A storage chassis or controller card can use PEX8712-CA80BC to consolidate multiple PCIe Gen 3 endpoints behind a 12-lane, 3-port switching fabric. The part is intended to provide scalable, non-blocking interconnection for storage systems, allowing the design to route controllers or expansion adapters without treating each endpoint as an isolated host link. Engineering validation should cover advertised versus negotiated link width, power states, reset behavior, reference clock quality, and the complete ball-map connectivity of the 324-pin FCBGA package.
अनुशंसित
Communications Infrastructure
PEX8712-CA80BC can support communications equipment that needs multiple PCIe Gen 3 endpoint connections arranged behind a high-bandwidth switch. Broadcom identifies communications platforms as an intended use for the PEX 8712 family, and the 12-lane, 3-port architecture is suited to scalable equipment with multiple cards, fabric interfaces, or accelerator relationships. The implementation should use the manufacturer reference design to preserve lane reach, signal-integrity margin, clocking, and controlled-impedance routing in the multilayer PCB.
अनुशंसित
Graphics and Acceleration Platform
The PEX8712-CA80BC is suitable for graphics platforms requiring PCIe Gen 3 fan-out to multiple display, capture, or processing endpoints. Broadcom explicitly includes graphics platforms among the PEX 8712 target applications, and its non-blocking switch capability can support a multi-device topology. Design teams should confirm supported operating-system and firmware configurations, link-training behavior, lane assignment, and the thermal budget for a dense accelerator board operating near the 3.5 W typical-power figure.
अनुशंसित
Industrial PCIe Adapter
An industrial adapter can use PEX8712-CA80BC when it must present several PCIe Gen 3 endpoint connections through a common switching fabric. The 3-port device provides a defined lane-fan-out resource for accelerator, storage, or acquisition cards, while the 40 nm Broadcom implementation is identified for high-bandwidth, non-blocking interconnection. Industrial enclosure temperatures and airflow conditions should be evaluated against the manufacturer thermal data, while the 324-pin FCBGA layout requires careful escape routing and power-plane distribution.
अनुशंसित
Multi-Host Test Platform
PEX8712-CA80BC can serve as the central PCIe switching element in a test platform that connects multiple hosts or endpoint boards for validation. The 12-lane, 3-port configuration gives the system designer a defined Gen 3 routing structure, and the non-blocking multi-host feature supports equipment that needs concurrent endpoint relationships. Lab use should account for the device's typical power, provide adequate cooling around the FCBGA, and use controlled launch and test procedures to validate each supported lane and configuration.

डिज़ाइन नोट्स
Use the Broadcom PEX 8712 reference design and package documentation as the authority for the 324-FCBGA layout. Plan high-speed lane escape routes with the final stack-up, via geometry, return-path continuity, and impedance targets selected before component placement. A 19 x 19 mm package with 324 balls leaves limited routing freedom, so escape strategy, decoupling placement, and power delivery should be evaluated together rather than as separate PCB tasks.
Estimated: begin the thermal budget with the manufacturer's 3.5 W typical-power figure and the actual ambient temperature, package thermal resistance, airflow, and board copper area. The junction-temperature estimate requires the thermal resistance value from the manufacturer datasheet, so no numerical junction temperature can be calculated here. Provide the FCBGA with uninterrupted thermal-via and copper pathways and verify the assembled board under the expected maximum lane and environmental conditions.
Do not treat the PEX8712-CA80BC and PEX8712-CA80BC-G strings as interchangeable without checking the manufacturer's ordering table. Also avoid treating a general PCIe switch as a drop-in replacement: confirm all 324 ball assignments, supply rails, reference-clock requirements, port configuration, firmware support, lane direction, reset behavior, and the platform reference design before making a substitution.
