SY10E111AEJY

Clock Buffers, Drivers Overview

The SY10E111AEJY is a low skew 1-to-9 differential clock driver manufactured by Microchip Technology, housed in a 28-pin PLCC package. It supports both 5V and 3.3V power supply options for ECL and PECL applications. The device accepts one signal input, which can be differential or single-ended using the VBB output, and fans it out to nine identical differential outputs. Key performance metrics include a maximum toggle frequency of 800 MHz, part-to-part skew of 200 ps, and within-device skew of 50 ps. An enable input allows the device to disable all outputs.

Clock Buffers, Drivers Feature Summary

• Low skew design with 200 ps part-to-part skew and 50 ps within-device skew
• Supports 5V (4.2V to 5.5V) and 3.3V (3.0V to 3.8V) power supplies
• Features an enable input that forces Q outputs LOW and Q outputs HIGH when logic HIGH
• Includes internal 75KΩ input pulldown resistors and voltage/temperature compensated outputs

Clock Buffers, Drivers Applications

• High-performance clock distribution across backplanes
• Board-level clock distribution in 5V and 3.3V systems
• PECL environment clock buffering and distribution

Clock Buffers, Drivers Procurement Notes

Verify component authenticity through authorized channels as the device originates from Micrel, now part of Microchip Technology. Confirm the J28-1 package type and Pb-free matte tin finish associated with the 'JY' suffix. Ensure compliance with RoHS standards if required for the specific application environment.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring precise timing alignment due to its guaranteed low skew specifications. Ensure proper termination of all differential output pairs into 50 Ω loads to maintain minimum skew; failure to terminate unused pairs on the same package side may degrade propagation delay by 10-20 ps. Verify compatibility with existing ECL or PECL logic levels.

Clock Buffers, Drivers Part Context

This component belongs to the Precision Edge SY10/100E111AE/LE series, designed specifically for low skew clock distribution. It serves as an upgrade to the standard SY10/100E111 with improved jitter performance and added low voltage operation capabilities. The device is fully compatible with industry-standard Motorola MC10/100E111 functions.

Clock Buffers, Drivers Replacement Considerations

The SY10E111AEJY is functionally compatible with the Motorola MC10E111 and MC100E111. Designers should verify pinout and electrical characteristics match their current design requirements when substituting these equivalent parts.
