SI53341-B-GMR

Clock Buffers, Drivers Overview

The SI53341-B-GMR is a low-jitter LVDS fanout clock buffer from the Si5334x family, manufactured by Skyworks Solutions. It features four LVDS outputs and accepts single-ended LVCMOS inputs via a 2:1 input multiplexer. The device operates over a frequency range of dc to 200 MHz with supply voltages of 1.8 V, 2.5 V, or 3.3 V. Key electrical specifications include an additive jitter of 150 fs rms (typical) at 156.25 MHz and output-to-output skew of 50 ps. It is housed in a 16-QFN package.

Clock Buffers, Drivers Feature Summary

• Four LVDS outputs with selectable input via 2:1 mux
• Ultra-low additive jitter: 150 fs rms typical at 156.25 MHz
• Wide frequency range: dc to 200 MHz
• Built-in LDOs for high PSRR performance

Clock Buffers, Drivers Applications

• Clock distribution in noisy environments
• Redundant clocking applications
• Low-jitter clock tree design

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix '-GMR' against the manufacturer's current documentation to confirm tape-and-reel packaging details. Confirm RoHS compliance status directly with the supplier. Check for any recent Product Change Notifications (PCN) that may affect pinout or material composition before finalizing procurement.

Clock Buffers, Drivers Selection Notes

Select this component when LVCMOS input compatibility is required alongside LVDS output distribution. Ensure the application frequency does not exceed 200 MHz. Verify that the power supply voltage matches the device's supported range of 1.8 V, 2.5 V, or 3.3 V. Consider the 16-QFN package size for PCB layout constraints.

Clock Buffers, Drivers Part Context

The SI53341-B-GMR belongs to the Si53340-45 family of low-jitter LVDS fanout buffers. This family includes variants with different input formats (universal vs. LVCMOS only) and output counts (4, 3, or 10). The SI53341 specifically targets LVCMOS inputs, distinguishing it from the universal input SI53340.

Clock Buffers, Drivers Replacement Considerations

SI53340-B-GM offers similar functionality but supports any-format inputs instead of LVCMOS only.
