Overview
The SI52112-B6-GTR is a dual-output PCIe clock generator from Skyworks Solutions, designed for PCI-Express Gen 1, Gen 2, and Gen 3 common clock applications. It supports Gen 3 SRNS specifications and features low-power HCSL differential output buffers. The device accepts a 25 MHz crystal or clock input and provides two outputs at frequencies up to 100 MHz. It operates on a 3.3 V supply with a maximum current of 17 mA and includes triangular spread spectrum modulation (-0.5% down) for EMI reduction. The component is housed in an 8-pin TSSOP package.
Feature Summary
- PCIe Gen 1, Gen 2, and Gen 3 common clock compliant
- Gen 3 SRNS compliant
- Low power HCSL differential output buffers
- Triangular spread spectrum profile for maximum EMI reduction
Applications
- Network attached storage
- Multi-function printer
- PCIe Add-on Cards
- Network Interface Cards
- Docking Stations
Procurement Notes
Verify the GTR suffix indicates tape and reel packaging for the 8-pin TSSOP variant. Confirm RoHS compliance and lead-free status as specified in the ordering guide. Ensure the extended temperature range (-40 to +85 °C) matches system requirements.
Selection Notes
Select this model over the B5 variant when spread spectrum functionality is required for EMI mitigation. Verify that the 8-pin TSSOP footprint fits the board layout constraints compared to the smaller 8-pin TDFN option.
Part Context
This part belongs to the Si52112-B5/B6 family of high-performance PCIe clock generators. The B6 designation specifically denotes support for -0.5% down spread outputs, distinguishing it from the non-spread B5 version.
Replacement Considerations

FAQ
Does the SI52112-B6 support Serial-ATA?
Yes, the device supports Serial-ATA (SATA) at 100 MHz.
What is the spread spectrum modulation frequency?
The modulation frequency is typically 31.5 kHz, ranging from 30 to 33 kHz.
Is termination resistor required for the outputs?
No, termination resistors are not required for the HCSL differential outputs.
