SY10E111LEJY

Clock Buffers, Drivers Overview

The SY10E111LEJY is a low skew 1-to-9 differential clock driver manufactured by Microchip Technology. It supports both 5V and 3.3V power supply options, making it suitable for ECL and PECL applications. The device features an enable input that disables outputs when asserted high. Key performance metrics include a maximum toggle frequency of 800 MHz, part-to-part skew of 200 ps, and output-to-output skew of 50 ps. It operates within a temperature range of -40°C to +85°C and is housed in a 28-pin PLCC package.

Clock Buffers, Drivers Feature Summary

• Low skew design with 200 ps part-to-part skew and 50 ps output-to-output skew
• Supports 5V and 3.3V power supplies for ECL and PECL compatibility
• Includes an enable input to force outputs LOW/HIGH when disabled
• Features voltage and temperature compensated outputs with 75KΩ input pulldown resistors

Clock Buffers, Drivers Applications

• High-performance clock distribution across backplanes
• Board-level clock distribution systems
• Systems requiring low jitter and precise timing alignment

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'JY' indicates a Pb-Free package with a Matte-Sn finish and a bar-line indicator as per the datasheet. Confirm the lead finish matches project requirements, as other suffixes like 'JI' or 'JC' indicate Sn-Pb finishes. Check current availability status directly with the manufacturer or authorized distributors.

Clock Buffers, Drivers Selection Notes

Select this component when low skew is critical for clock distribution. Ensure termination resistors are used on all differential output pairs to maintain specified skew margins. Verify that the system operates within the -4.2V to -5.5V (ECL) or +3.0V to +3.8V/+4.2V to +5.5V (PECL) supply ranges. Consider the 800 MHz maximum toggle frequency limit for signal integrity.

Clock Buffers, Drivers Part Context

This device belongs to the Precision Edge SY10/100E111AE/LE family. It is functionally similar to the standard SY10/100E111 but offers improved low jitter and low voltage operation capabilities. It is fully compatible with industry standards such as Motorola MC10/100E111.

Clock Buffers, Drivers FAQ

How does the Enable input affect the outputs?

A logic HIGH on the Enable input disables the device, forcing all Q outputs LOW and all Q-bar outputs HIGH.

What is the impact of unterminated outputs on skew?

Failure to terminate unused output pairs on the same package side as active pairs can degrade propagation delay by 10-20 ps, resulting in a loss of skew margin.

Can the device accept single-ended inputs?

Yes, the device accepts either differential or single-ended signals if the VBB output is utilized.
