SI53152-A01AGMR

Overview

The SI53152-A01AGMR is a PCIe Gen 1, 2, 3, and 4 compliant fan-out clock buffer manufactured by Skyworks Solutions. It sources two differential PCIe clocks simultaneously from a single input within the 100–210 MHz frequency range. The device operates on a 3.3 V supply (3.135–3.465 V) and features low-power push-pull output buffers with internal termination. It supports spread spectrum tolerance and includes dedicated hardware output enable pins for each clock output.

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 internal 100 kΩ pull-ups

Applications

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

Procurement Notes

Verify the ordering suffix 'GMR' corresponds to the tape and reel packaging format as specified in the manufacturer's ordering guide. Confirm that the extended temperature rating of -40°C to +85°C meets the operational requirements of the target system environment.

Selection Notes

Select this component when a 1:2 fan-out ratio is required for high-speed serial interfaces. Ensure the design accommodates the 24-pin QFN package dimensions (4x4 mm). Verify that the I2C slave address (D6h) does not conflict with other devices on the bus.

Part Context

This part belongs to the Si53152 family of PCIe clock buffers. The specific model SI53152-A01AGMR denotes the tape and reel variant, whereas the 'GM' suffix indicates tray packaging. Both variants share identical electrical specifications and pinouts.

Replacement Considerations

The SI53152-A01AGM is a direct functional replacement offering identical performance in tray packaging. No other cross-model substitutes are confirmed in the provided documentation.
