SY10E111AEJI

Clock Buffers, Drivers Overview

The SY10E111AEJI is a low skew 1-to-9 differential clock driver manufactured by Microchip Technology. It operates with 5V and 3.3V power supply options, featuring an enable input that disables the device when logic HIGH. The component 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 electrical specifications include a maximum toggle frequency of 800 MHz, part-to-part skew of 200 ps, and within-device skew of 50 ps. It utilizes a 28-pin PLCC package.

Clock Buffers, Drivers Feature Summary

• Low skew design with 200 ps part-to-part skew and 50 ps within-device skew
• Supports 5V and 3.3V power supply options for ECL and PECL applications
• Includes an enable input to disable all Q outputs (LOW) and Q outputs (HIGH)
• Features internal 75KΩ input pulldown resistors and voltage/temperature compensated outputs

Clock Buffers, Drivers Applications

• Clock distribution in high-performance systems
• Backplane clock distribution
• Board-level clock distribution

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'JI' corresponds to the J28-1 industrial package with Sn-Pb lead finish as specified in the datasheet. Confirm the specific series (SY10 vs SY100) matches the required voltage range: -4.75V to -5.5V for SY10E111AEJI and -4.2V to -5.5V for SY100E111AEJI. Ensure compatibility with existing inventory regarding lead-free requirements if applicable.

Clock Buffers, Drivers Selection Notes

Select this component when low skew is critical for clock distribution across multiple loads. The device supports both differential and single-ended inputs via the VBB pin. Designers must terminate both sides of the differential outputs into 50 Ω to maintain minimum skew specifications, even if only one side is utilized. The enable input provides control over the output state.

Clock Buffers, Drivers Part Context

The SY10E111AEJI belongs to the Precision Edge SY10/100E111AE/LE family. It is functionally similar to the popular SY10/100E111 but offers improved performance with lower jitter and support for low voltage operation. The device is fully compatible with Motorola MC10/100E111 standards.

Clock Buffers, Drivers Replacement Considerations

The datasheet states full compatibility with Motorola MC10/100E111. No other specific replacement part numbers are listed in the provided documentation.
