SI53102-A3-GM

Overview

The SI53102-A3-GM is a high-performance 1:2 PCIe fan-out clock buffer compliant with PCI-Express Gen 1, Gen 2, Gen 3, and Gen 4 specifications. Designed for consumer and embedded applications, it features an ultra-small 8-pin TDFN package measuring 1.4 x 1.6 mm. The device supports both 2.5 V and 3.3 V power supplies with a maximum operating supply current of 15 mA. It accepts differential clock inputs up to 175 MHz and provides two low-power differential outputs without requiring external termination resistors.

• Ultra-Small 8-Pin TDFN Package (1.4 x 1.6 mm)
• Dual Low-Power Differential Outputs
• No External Termination Resistors Required

Applications

• Network Attached Storage
• Multi-function Printer
• Wireless Access Point
• Server/Storage Systems

Procurement Notes

Verify the specific ordering suffix 'GM' indicates the standard tape-and-reel packaging configuration as listed in the manufacturer's ordering guide. Confirm that the component meets RoHS compliance standards and check for any end-of-life notices or obsolescence warnings directly from Skyworks Solutions documentation before finalizing procurement plans.

Selection Notes

Select the SI53102-A3 variant specifically for designs requiring support for PCIe Gen 3 and Gen 4 signaling speeds. Ensure the design accommodates the required 2.5 V or 3.3 V supply voltage ranges and strictly adheres to the recommended land pattern dimensions provided in the datasheet to maintain signal integrity within the compact 8-pin TDFN footprint.

Part Context

This component belongs to the Si53102-A1/A2/A3 family of low-additive-jitter clock buffers. The '-A3' designation identifies this specific part as optimized for PCIe Gen 3 and Gen 4 performance requirements, distinguishing it from the A1 (Gen 1) and A2 (Gen 2) variants within the same product line.

Replacement Considerations

Direct replacements within the same family include the SI53102-A1-GM and SI53102-A2-GM, though these are specified only for Gen 1 and Gen 2 respectively. Verify compatibility if upgrading from older generations, as the A3 variant offers lower jitter specifications necessary for higher-speed interfaces.
