SI53102-A3-GMR

Product Overview

The SI53102-A3-GMR is a Skyworks Solutions Inc. clock buffer intended for PCI Express (PCIe) timing distribution. The device accepts a differential clock input and provides a 1:2 differential clock output ratio, with a maximum specified frequency of 100MHz. It is supplied in an 8-WFDFN exposed-pad package, identified by the supplier device package as 8-TDFN (1.4x1.6), and uses surface-mount mounting. The specified supply voltage range is 2.25V to 3.63V, and the operating temperature range is -40°C to 85°C. The listed product status is Last Time Buy.

Key Features

• PCI Express (PCIe) clock buffer with a 1:2 input-to-output ratio.
• Differential clock input and differential clock output.
• Maximum specified frequency of 100MHz.
• Supply voltage range of 2.25V to 3.63V.
• Operating temperature range of -40°C to 85°C.
• Surface-mount 8-WFDFN exposed-pad package, supplier device package 8-TDFN (1.4x1.6).
• The supplied product data lists PLL as No.

Applications

• PCIe endpoint modules that need differential reference-clock fan-out from a single clock source.
• PCIe switch or expansion subsystems distributing a 100MHz clock to downstream interface circuitry.
• Embedded PCIe add-in cards or backplane modules using surface-mount timing distribution in an 8-TDFN (1.4x1.6) package.

Design & Procurement Notes

Designers should verify that the PCIe timing architecture uses differential clock signaling and that the required output count matches the 1:2 ratio. The 2.25V to 3.63V supply range and -40°C to 85°C operating range should be checked against the system power rails and ambient conditions. Board layout should accommodate the 8-TDFN (1.4x1.6) surface-mount package and exposed pad. Because the supplied status is Last Time Buy, procurement planning should consider long-term availability for designs that require continued production.
