The ASMedia ASM1187E is a PCIe Gen2 to PCI bridge. This chip is commonly used to expand the number of PCI Express slots available on a motherboard or other device. It takes one PCIe upstream port and splits it into multiple downstream PCI Express ports.

Applications

• Motherboards
• Industrial PCs
• Embedded Systems
• Any system requiring additional PCIe slots

Features

• PCI Express Base Specification Revision 2.0 compliant
• Supports 1 upstream port and up to 7 downstream ports
• Integrated SerDes with internal PLL
• Supports packet traffic control
• Supports spread spectrum clocking (SSC)
• Automatic Lane Reversal
• I2C master interface for flexible configuration
• Supports EEPROM or SMBus for configuration
• Low power consumption
• Lead-free and RoHS compliant

Benefits

• Increases the number of available PCIe slots, enhancing system expandability.
• Provides a cost-effective solution for adding PCIe functionality.
• Offers flexible configuration options through I2C or EEPROM.
• Reduces system cost and complexity compared to using multiple PCIe controllers.
• Ensures reliable operation with features like SSC and automatic lane reversal.

Additional Details

The ASM1187E is a low-power PCIe packet switch which provides high performance and flexible configurations. It allows for the efficient utilization of PCIe lanes, making it ideal for applications where multiple PCIe devices need to be connected to a single host. Its integrated SerDes and PLL contribute to its low power consumption and compact size.
