SY100EL14VZC

Clock Buffers, Drivers Overview

The SY100EL14V is a low-skew, 1:5 clock distribution chip designed for high-performance timing applications. It supports differential or single-ended ECL/PECL inputs and operates with 3.3V to 5.0V supplies. The device features multiplexed clock input capability and synchronous enable/disable control to prevent runt pulses. Key electrical parameters include a typical output-to-output skew of 30ps (max 50ps) and 70fs RMS additive phase jitter at 622MHz. Propagation delay ranges from 520ps to 830ps depending on temperature. It is housed in a 20-pin narrow SOIC package.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix when sourcing this component. The base model SY100EL14V requires a suffix such as ZG for industrial temperature range availability. Confirm lead times and stock levels with authorized distributors, as availability may vary based on production status and regional restrictions.

Clock Buffers, Drivers Selection Notes

Select the SY100EL14V for designs requiring precise clock synchronization across multiple loads. Ensure the system voltage matches the 3.3V or 5V operating range. For single-ended inputs, connect VBB to /CLK and bypass to ground. Verify that the required propagation delay and jitter specifications align with the target application's timing budget.

Clock Buffers, Drivers Part Context

This component belongs to the SY100E series of high-speed logic devices originally manufactured by Micrel, which was acquired by Microchip Technology. The part is designed for telecommunications and high-speed computing environments where signal integrity and low jitter are critical requirements.

Clock Buffers, Drivers Replacement Considerations

Check for direct pin-compatible replacements within the same family, such as the SY100EL14ZG. Verify that any substitute maintains the same 1:5 distribution ratio, ECL/PECL compatibility, and 20-pin SOIC package form factor.
