SI53152-A01AGM

Overview

The SI53152-A01AGM is a PCIe Gen 1, 2, 3, and 4 compliant fan-out buffer manufactured by Skyworks Solutions. It sources two differential PCIe clocks simultaneously from a single differential input (100–210 MHz). The device operates on a 3.3 V supply with a typical dynamic current of 20 mA at 100 MHz. It features low-power push-pull output buffers with internal termination, supporting LVDS outputs. Key electrical parameters include an additive peak jitter of 10 ps and a clock skew of 50 ps.

Feature Summary

• PCIe Gen 1/2/3/4 common clock compliance
• Spread spectrum tolerant operation
• I2C programmability for skew, edge rate, and amplitude control
• Dedicated hardware OE pins with I2C readback capabilities

Applications

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

Procurement Notes

Verify the ordering suffix 'GM' corresponds to the 24-pin QFN package in the official Skyworks Ordering Guide. Confirm that the specific revision code matches the required design specifications before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring simultaneous distribution of two buffered PCIe clocks. Ensure the input frequency falls within the 100–210 MHz range. Verify that the 3.3 V power supply voltage remains within the specified 3.135 V to 3.465 V limits for proper operation.

Part Context

This part belongs to the Si53152 family of spread spectrum tolerant PCIe clock buffers. It is designed to replace multiple discrete components by integrating internal termination and providing flexible output control via I2C or hardware pins.

Replacement Considerations

The SI53152-A01AGMR is the tape-and-reel version of this component. Both share identical electrical characteristics and pinouts but differ only in packaging format.
