SI53112-A00AGM

Overview

The Si53112-A00AGM is a low-power, 12-output differential clock buffer designed to meet Intel DB1200ZL specifications. It supports 100 MHz and 133 MHz operation for PCIe Gen 1/2/3/4, SAS, SATA, QPI, and SMI applications. The device features individual hardware output enable pins for each of the twelve 0.7 V push-pull outputs. It operates on a 3.3 V core supply and a 1.05 V to 3.3 V I/O supply. Key electrical parameters include 50 ps output-to-output skew and 50 ps cyc-cyc jitter in PLL mode.

Feature Summary

• Twelve 0.7 V low-power, push-pull, HCSL-compatible PCIe Gen 3 outputs
• Individual OE HW pins for each output clock
• 100 MHz / 133 MHz PLL operation, supports PCIe and QPI
• SMBus address configurable to allow multiple buffers in a single control network

Applications

• Server
• Storage
• Datacenter
• Enterprise Switches and Routers

Procurement Notes

Verify the ordering suffix A00AGM against the manufacturer's current ordering guide to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements as stated in the datasheet. Confirm that the 64-pin QFN package dimensions match the target PCB land pattern design.

Selection Notes

Select this component when distributing reference clocks for Intel Quick-Path Interconnect or PCIe Gen 1 through Gen 4 interfaces. The device requires a 3.3 V core supply and supports an I/O voltage range from 1.05 V to 3.3 V. Consider the 50 ps output-to-output skew and low phase jitter characteristics for high-speed signal integrity requirements.

Part Context

The Si53112 is part of Skyworks Solutions' DB1200ZL compliant buffer family. It is optimized for distributing reference clocks in server and storage environments. The device supports both PLL and bypass modes, with programmable bandwidth via SMBus or hardware pins.
