SY898533LKZ

Clock Buffers, Drivers Overview

The SY898533LKZ is a Precision Differential 3.3V Low-Skew LVPECL 1:4 Fanout Buffer manufactured by Microchip Technology. It provides four differential 3.3V LVPECL copies and features two selectable clock input pairs (CLK, /CLK and PCLK, /PCLK). The device operates from a 3.3V ±5% supply voltage within a 0°C to +70°C temperature range. Key electrical specifications include a maximum output frequency of 650 MHz, propagation delay under 1.4 ns, output skew under 30 ps, and typical additive phase jitter of 145 fs RMS.

Clock Buffers, Drivers Feature Summary

• Provides four differential 3.3V LVPECL outputs with low skew characteristics
• Features two selectable differential input pairs for flexible signal compatibility
• Guaranteed AC performance up to 650 MHz with <30 ps output skew
• Includes synchronous clock enable functionality to prevent runt pulses

Clock Buffers, Drivers Applications

• SONET Clock Distribution
• Backplane Distribution
• LAN/WAN Systems
• Enterprise Servers
• ATE and Test and Measurement Equipment

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'KZ' corresponds to the 20-Lead TSSOP package and 0°C to +70°C industrial temperature range as defined in the Product Identification System. Confirm whether the required quantity necessitates the tube packaging or if the tape and reel variant (SY898533LKZ-TR) is preferred for automated assembly processes.

Clock Buffers, Drivers Selection Notes

Select this component when a low-skew LVPECL fanout buffer is required for high-speed clock distribution. Ensure the design accommodates the 3.3V ±5% supply requirement and that the operating environment remains within the specified 0°C to +70°C range. Verify that the input signal levels match the supported standards for either the CLK or PCLK input pairs.

Clock Buffers, Drivers Part Context

The SY898533LKZ belongs to Microchip’s Precision Edge product line, designed for high-speed digital applications. It serves as a 1:4 fanout buffer, converting a single differential input into four buffered LVPECL outputs. This specific part number denotes the standard commercial/industrial temperature version packaged in a 20-lead TSSOP housing.
