Product details
Overview
PI7C9X2G608GP from Diodes Incorporated is a PCI Express Gen 2 packet switch with 6 ports and 8 total lanes, supporting transparent bridging, hot-plug, AER, and ACS. It operates at 2.5 GT/s per lane, features integrated 8K-byte configuration space, and supports PCIe 2.0 root complex and endpoint topologies in embedded computing and industrial control systems.
For engineers reviewing the PI7C9X2G608GP datasheet, PI7C9X2G608GP pinout, PI7C9X2G608GP application, or PI7C9X2G608GP equivalent, key selection criteria include port-lane flexibility (e.g., x4+x1+x1+x1+x1), EEPROM-based configuration, SMBus/I²C system management, and compliance with PCIe Base Specification Rev 2.0.
Technical Context
The PI7C9X2G608GP implements a full PCIe 2.0 transaction layer with TLP decapsulation/encapsulation, credit-based flow control, and VC arbitration across six configurable downstream/upstream ports. Its physical layer includes receiver equalization, programmable de-emphasis (−3.5 dB, −6 dB), and transmitter swing control for robust signal integrity on FR-4 PCBs.
It supports transparent mode operation without host BIOS modification, uses an internal 8K-byte configuration space mapped to standard PCIe registers, and enables dynamic port reconfiguration via SMBus or I²C slave interface - critical for modular server backplanes and reconfigurable industrial I/O hubs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PCIe Generation | Gen 2 (2.5 GT/s per lane) - ensures backward compatibility with Gen 1 and sufficient bandwidth for mid-tier storage and I/O expansion. |
| Total Lanes | 8 lanes - allocatable across 6 ports (e.g., x4+x1+x1+x1+x1) to match host CPU and peripheral bandwidth requirements. |
| Port Count | 6 ports - supports flexible topology: one upstream + five downstream, or multi-root configurations with port bifurcation. |
| Configuration Space | 8 KB integrated - eliminates external configuration EEPROM dependency for basic operation; retains full PCIe-compliant register map. |
| Management Interface | SMBus/I²C slave - enables out-of-band firmware updates, runtime port enable/disable, and thermal/power telemetry without PCIe enumeration. |
| Power Supply | 1.05 V core / 3.3 V I/O - dual-rail operation aligns with standard PCIe slot power delivery and simplifies board-level regulation. |
| Operating Temperature | −40°C to +85°C - qualified for extended industrial environments including factory automation and transportation control systems. |
Pinout & Package
Package: 196-pin LBGA (12 mm × 12 mm, 0.8 mm pitch), RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK_IN | Reference clock input | Accepts 100 MHz differential LVDS clock; required for PCIe link training and timing synchronization across all ports. |
| PERST# | Global reset input | Active-low asynchronous reset that clears configuration registers and forces re-initialization of all PCIe links. |
| SCL / SDA | SMBus/I²C interface | Enables host-side register read/write without PCIe enumeration - used for debug, field updates, and thermal monitoring. |
| EEPROM_CLK / EEPROM_DATA | Serial EEPROM interface | Loads initial configuration (port mapping, vendor ID, device ID) at power-on before PCIe enumeration begins. |
| PRSNT#_A–F | Hot-plug presence detect | Individual port presence signals allow detection of card insertion/removal per downstream slot without system reboot. |
Key Features
| Feature | Design Value |
|---|---|
| Transparent bridging mode | Operates without BIOS or OS driver modification - preserves existing PCIe enumeration flow while adding port expansion. |
| Programmable lane allocation | Supports 13 predefined port-lane configurations (e.g., x4+x1+x1+x1+x1) via EEPROM or SMBus, enabling hardware-defined topology. |
| Advanced Error Reporting (AER) | Full PCIe AER capability with error injection and logging - essential for fault-tolerant industrial controllers and telecom base stations. |
| ACS (Access Control Services) | Enables IOMMU-aware virtualization by enforcing source validation and request filtering between downstream devices. |
| Hot-plug support per port | Dedicated PRSNT# pins and associated logic allow safe insertion/removal of PCIe cards on individual downstream ports. |
Applications
| Industrial PC Expansion | Modular Test Equipment |
|---|---|
Use Scenario: Adding multiple PCIe peripherals (DAQ, motion control, vision capture) to a compact IPC chassis with limited motherboard slots. IC Role / Device Role / Timing Role: PCIe Gen 2 packet switch acting as transparent bridge between CPU root port and five downstream add-in modules. Use Value: Enables single-slot expansion into six functional endpoints while maintaining native PCIe enumeration and driver compatibility. | Use Scenario: Reconfigurable automated test system where instrument modules (DMM, SMU, waveform generator) are hot-swapped during calibration cycles. IC Role / Device Role / Timing Role: Hot-plug-aware PCIe switch managing isolated downstream port power and presence detection per module slot. Use Value: Eliminates system downtime during module replacement and ensures PCIe link retraining completes within <500 ms per port. |
| Embedded Network Appliance | Medical Imaging Subsystem |
Use Scenario: Integrating dual 10GbE NICs, SATA controller, and FPGA co-processor onto a single PCIe x4 upstream interface in a firewall appliance. IC Role / Device Role / Timing Role: Lane-bifurcated PCIe switch allocating x2 to each NIC, x2 to SATA/FPGA, with ACS-enforced traffic isolation. Use Value: Provides hardware-level DMA protection between network and storage domains, satisfying IEC 62443-3-3 security requirements. | Use Scenario: Connecting high-speed image sensors (CMOS, CCD), real-time GPU accelerator, and DICOM storage controller in portable ultrasound equipment. IC Role / Device Role / Timing Role: Low-latency PCIe 2.0 switch routing sensor frame data directly to GPU memory with deterministic <1.2 µs packet forwarding delay. Use Value: Maintains sub-10 ms end-to-end imaging pipeline latency while supporting concurrent DICOM export over separate PCIe lane. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PCIe Gen 2 switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ASM1083 | 3-port, 4-lane, no SMBus/I²C management, no AER or ACS | Limited to simple x4 split; unsuitable for hot-plug or secure virtualized systems | Select when cost-sensitive, fixed-topology designs require only basic lane bifurcation. |
| PI7C9X2G304BP | 4-port, 4-lane, identical feature set but reduced port count and lower power (1.5 W vs. 2.3 W) | Better suited for space-constrained edge gateways with fewer expansion needs | Choose for footprint- and power-constrained deployments where 6-port scalability is unnecessary. |
Compared with ASM1083 and PI7C9X2G304BP, the PI7C9X2G608GP delivers higher port density, comprehensive PCIe 2.0 management features (AER, ACS, SMBus), and industrial temperature support - making it optimal for reconfigurable, safety-aware, and field-upgradable systems.

FAQ
Does the PI7C9X2G608GP support PCIe Gen 3?
No. The PI7C9X2G608GP is compliant only with PCIe Base Specification Revision 2.0, operating at 2.5 GT/s. It does not negotiate or function at 5.0 GT/s and will fall back to Gen 2 if connected to a Gen 3 root port. Gen 3 support requires different PHY architecture and is not implemented in this device.
Can port configuration be changed after power-up?
Yes. Port-lane mapping can be dynamically reconfigured via SMBus or I²C slave interface using the OPERATION MODE register (offset 98h), provided the target port is disabled first. This allows runtime topology adaptation without full device reset, subject to PCIe link retraining delays.
Is an external EEPROM required for operation?
No. The PI7C9X2G608GP includes 8 KB of internal configuration space and can operate in "no-EEPROM" mode using default settings. External EEPROM is optional and used only to override defaults (e.g., custom vendor ID, port mapping) at power-on reset.
What thermal management is recommended?
A 4-layer PCB with ≥2 oz copper, thermal vias under the package center, and a minimum 100 mm² exposed pad connected to internal ground plane is required. Junction temperature must remain ≤115°C; typical power dissipation is 2.3 W at full load with 1.05 V core and 3.3 V I/O supplies.
