SI53102-A3-GMR

Overview

The SI53102-A3-GMR is a high-performance 1:2 fan-out clock buffer compliant with PCIe Gen 1, Gen 2, Gen 3, and Gen 4 specifications. Designed for low-additive-jitter applications, it operates on a single 2.5 V or 3.3 V supply with a maximum operating current of 15 mA. The device accepts differential inputs up to 175 MHz and provides two differential outputs. It features spread spectrum tolerance and requires no external termination resistors for differential clocks. Packaged in an ultra-small 8-pin TDFN (1.4 x 1.6 mm) footprint, it supports an extended operating temperature range from –40 °C to +85 °C.

Feature Summary

PCIe Gen 1 through Gen 4 common clock compliance
Low additive jitter: 0.22 ps RMS for PCIe Gen 3/4 at 3.3 V
Supports Serial-ATA (SATA) at 100 MHz
No external termination resistors required for differential clocks

Applications

Network Attached Storage
Multi-function Printer
Wireless Access Point
Server/Storage

Procurement Notes

Verify the 'GMR' suffix indicates tape and reel packaging as specified in the ordering guide. Confirm the 'A3' designation matches requirements for PCIe Gen 3 and Gen 4 compatibility. Check datasheet revision history for updates to AC electrical specifications before finalizing design integration.

Selection Notes

Select the SI53102-A3 variant specifically for PCIe Gen 3 and Gen 4 designs; A1 and A2 variants are intended for lower generation standards. Ensure power supply voltage aligns with the specific jitter performance targets, as Gen 3/4 jitter specs differ between 2.5 V and 3.3 V operation. Verify input frequency does not exceed the 175 MHz maximum limit.

Part Context

This component belongs to the Si53102-A1/A2/A3 family of 1:2 fan-out buffers. The 'A3' suffix distinguishes it from the A1 (Gen 1) and A2 (Gen 2) variants by supporting higher-speed PCIe generations. The 'GM' suffix denotes tube packaging, while 'GMR' specifies tape and reel packaging for automated assembly.
