SI5351A-B-GMR

Product Overview

Skyworks Solutions Inc. SI5351A-B-GMR is a MultiSynth™ clock generator IC for surface-mount timing designs. The device accepts a crystal input and uses an LVCMOS output format, with a maximum frequency of 200MHz and a 1:8 input-to-output ratio. It contains two circuits and includes PLL functionality. The operating supply voltage range is 1.71V ~ 3.6V, and the temperature range is -40°C ~ 85°C. The part is housed in a 20-VFQFN Exposed Pad package, with a 20-QFN (4x4) package designation.

Design & Procurement Notes

Design and procurement considerations begin with matching the 1.71V ~ 3.6V supply range to the board power rail and confirming that the -40°C ~ 85°C temperature range suits the intended environment. The crystal input should be evaluated with the selected board reference, while the LVCMOS output should be checked against the receiving logic family and clock load conditions. The 20-VFQFN Exposed Pad package and 20-QFN (4x4) footprint require suitable surface-mount pad layout and thermal relief planning. Use the exact manufacturer part number SI5351A-B-GMR for design traceability and ordering.
