SI53154-A01AGM

Overview

The SI53154-A01AGM is a quad fanout buffer compliant with PCI-Express Gen 1, Gen 2, Gen 3, and Gen 4 common clock standards. It operates within a frequency range of 100 MHz to 210 MHz and supports Serial ATA at 100 MHz. The device features four differential outputs with internal termination, powered by a 3.3 V supply (3.135 V to 3.465 V). It includes dedicated hardware output enable pins for each channel and I2C programmability for dynamic control of skew, edge rate, and amplitude. The component is housed in a 24-pin QFN package and functions across an extended temperature range of –40 °C to 85 °C.

Feature Summary

• PCIe Gen 1 through Gen 4 compliant quad fanout buffer
• Four differential outputs with individual hardware OE controls
• I2C interface for dynamic adjustment of skew, edge rate, and amplitude
• Spread spectrum tolerant input operation

Applications

• Network attached storage systems
• Multi-function printers
• Wireless access points
• Routers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type. The 'GM' suffix indicates a tray package, while the 'GR' suffix denotes tape and reel packaging. Ensure the required operating temperature range matches the extended specification (-40 °C to 85 °C) before procurement.

Selection Notes

Select this component when designing systems requiring low additive jitter for PCIe or SATA interfaces. Verify that the input frequency falls between 100 MHz and 210 MHz. Confirm that the system power supply remains within the 3.135 V to 3.465 V range. Consider the I2C interface requirements if dynamic signal integrity adjustments are necessary.

Part Context

The SI53154-A01AGM belongs to the Skyworks SI53154 series of precision clock buffers. This series is designed to distribute high-speed reference clocks to multiple endpoints while maintaining signal integrity. The A01AGM variant specifically provides the standard tray packaging configuration for the extended industrial temperature grade.

Replacement Considerations

The SI53154-A01AGMR serves as the direct functional equivalent packaged in tape and reel format instead of trays. Other members of the SI5315x family may offer different output counts but require verification of pin compatibility and electrical specifications.
