SY89854UMY TR

Clock Buffers, Drivers Overview

The SY89854UMY TR is a precision, high-speed, fully differential 1:4 LVPECL fanout buffer and translator manufactured by Microchip Technology. It operates from a 2.5V ±5% or 3.3V ±10% supply within the industrial temperature range of –40°C to +85°C. The device processes clock signals up to 2GHz (fMAX) with less than 20ps skew and under 10ps total jitter. It features internal termination for AC- or DC-coupled inputs as small as 100mV and provides four identical 800mV LVPECL outputs.

Clock Buffers, Drivers Feature Summary

• Unique patent-pending input termination architecture accepts CML, PECL, and LVDS signals without external resistors
• Available in an ultra-small 3mm x 3mm 16-pin QFN package

Clock Buffers, Drivers Applications

• SONET and All GigE clock distribution
• Fibre Channel clock and data distribution
• Backplane distribution

Clock Buffers, Drivers Procurement Notes

Verify the specific 'MY' suffix against official documentation, as standard listings typically use 'MG'. Confirm the tape and reel packaging status directly with the manufacturer or authorized distributors. Ensure the component meets RoHS compliance requirements for the intended assembly process.

Clock Buffers, Drivers Selection Notes

Select this component when low skew (<20ps) and ultra-low jitter are critical for clock distribution networks. It supports both 2.5V and 3.3V supplies, making it versatile for mixed-voltage systems. The internal termination simplifies interface designs for various differential signaling standards like LVDS and CML.
