SY100EL15LZI-TR

Clock Buffers, Drivers Overview

The SY100EL15LZI-TR is a low skew 1:4 clock distribution IC from the Precision Edge series, manufactured by Microchip Technology. It operates on a 3.3V power supply and features a multiplexed clock input allowing selection between differential/PECL (CLK) and single-ended ECL (SCLK) sources via the SEL pin. The device includes a synchronous enable (EN) to prevent runt pulses and provides four differential outputs with an output-to-output skew of 50ps typical. Propagation delay ranges from 420ps to 750ps depending on the input source and temperature. It is housed in a 16-pin SOIC package.

Clock Buffers, Drivers Feature Summary

• Multiplexed clock input supporting differential, PECL, or single-ended ECL signals
• Synchronous enable/disable control to eliminate runt clock pulses
• Low output-to-output skew of 50ps typical
• Internal 75KΩ input pull-down resistors

Clock Buffers, Drivers Applications

• Low skew clock distribution networks
• System clock distribution for high-speed digital circuits
• Multiplexing scan/test clocks with system clocks

Clock Buffers, Drivers Procurement Notes

Verify the component status as the datasheet indicates Micrel was acquired by Microchip. Confirm availability through official Microchip channels as older Micrel-branded parts may have specific lifecycle statuses. Ensure the ordering suffix matches the required industrial temperature range (-40°C to +85°C) and tape-and-reel packaging.

Clock Buffers, Drivers Selection Notes

Select this part when a 1:4 split with minimal skew is required for 3.3V systems. Ensure the input signal type matches the selected pin configuration (CLK vs SCLK). Verify that the synchronous enable timing requirements (setup time 150ps, hold time 400ps) fit within the system design constraints.

Clock Buffers, Drivers Part Context

This component belongs to the SY100EL15L family of clock drivers originally developed by Micrel, Inc., which is now part of Microchip Technology. The 'Z' denotes the 16-pin SOIC package, 'I' indicates the industrial temperature range, and 'TR' specifies the tape and reel packaging format.

Clock Buffers, Drivers Replacement Considerations

Check for SY100EL15LZG-TR for lead-free versions within the same package and temperature range. Other SY100EL series devices may offer similar functionality but require verification of pinout compatibility and electrical specifications.
