SY100E111AJC

Clock Buffers, Drivers Overview

The SY100E111AJC is a low skew 1-to-9 differential clock driver manufactured by Microchip Technology under the Precision Edge series. It operates with 5V or 3.3V power supplies and accepts one signal input, which can be differential or single-ended using the VBB output. The device fans out the signal to nine identical differential outputs. Key electrical specifications include a typical part-to-part skew of 200ps and an output-to-output skew of 50ps. It features voltage and temperature compensated outputs, internal 75KΩ input pulldown resistors, and is housed in a 28-pin PLCC package.

Clock Buffers, Drivers Feature Summary

• Low skew design with 200ps part-to-part skew and 50ps output-to-output skew
• Supports both 5V and 3.3V power supply options for PECL operation
• Includes a VBB output reference voltage generator
• Features internal 75KΩ input pulldown resistors

Clock Buffers, Drivers Applications

• High-performance clock distribution across backplanes
• Board-level clock distribution systems
• Systems requiring low jitter differential clock signals

Clock Buffers, Drivers Procurement Notes

Verify component status as the datasheet indicates this product is not recommended for new designs. Confirm lead finish specifications, as the 'JC' suffix denotes commercial temperature range with Sn-Pb finish. Check current availability through authorized distributors as original manufacturing may have ceased.

Clock Buffers, Drivers Selection Notes

Select the SY100E111AJC when a 1:9 differential fanout buffer is required with tight skew constraints. Ensure termination requirements are met; all unused differential pairs on the same package side as active outputs must be terminated into 50Ω to maintain minimum skew specifications. Verify compatibility with existing Motorola MC100LVE111 designs if applicable.

Clock Buffers, Drivers Part Context

This component belongs to the Precision Edge SY10/100E111A/L family. The 'SY100' prefix typically denotes specific performance or packaging variations within the Micrel/Microchip ECL portfolio. The 'AJC' suffix specifies the Industrial/Commercial temperature range and 28-pin PLCC package configuration.

Clock Buffers, Drivers Replacement Considerations

The datasheet notes full compatibility with the Motorola MC100LVE111. Designers should verify pinout and electrical parameter equivalence before substitution.
