SY100EL14VZI

Clock Buffers, Drivers Overview

The SY100EL14VZI is a low-skew, 1:5 clock distribution chip designed for high-speed timing applications. It supports differential or single-ended ECL/PECL inputs and operates on 3.3V to 5.0V supplies. The device features a multiplexed clock input for scan/test clock integration and a synchronous enable/disable function to prevent runt pulses. Key electrical parameters include a typical output-to-output skew of 30ps (max 50ps), propagation delay of 680ps at +25°C, and 70fs RMS additive phase jitter. It is housed in a 20-pin narrow SOIC package.

Clock Buffers, Drivers Feature Summary

• Low-skew 1:5 clock distribution with typical 30ps output-to-output skew
• Multiplexed clock input supporting differential, single-ended, or scan clocks
• Synchronous enable/disable logic prevents runt clock pulse generation
• Operates on 3.3V or 5.0V power supplies with PECL/ECL compatibility

Clock Buffers, Drivers Applications

• Processor clock distribution
• SONET clock distribution
• Fibre Channel clock distribution
• Gigabit Ethernet clock distribution

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'ZI' against official documentation, as standard datasheets list 'ZG' variants. Confirm current availability status, as Micrel products may have transitioned through acquisition channels. Ensure compliance with humidity sensitivity levels and handling precautions required for ECL logic families.

Clock Buffers, Drivers Selection Notes

Select this component when low-jitter clock distribution is critical for system synchronization. The synchronous enable feature is essential for designs requiring glitch-free clock gating. Verify that the input signal swing meets the minimum 150mV requirement and that the supply voltage aligns with the 3.3V or 5V operating range specified in the DC characteristics.

Clock Buffers, Drivers Part Context

The SY100EL14V belongs to the EL series of high-speed ECL/PECL clock drivers originally manufactured by Micrel, Inc. This family is engineered for telecommunications and high-performance computing environments where precise timing and minimal skew are mandatory. The device serves as a fan-out buffer for distributing reference clocks to multiple downstream components.

Clock Buffers, Drivers Replacement Considerations

Direct replacements must match the 1:5 fan-out ratio, ECL/PECL interface, and 20-pin SOIC package. Verify that alternative devices offer comparable skew specifications (<50ps) and support the same supply voltage ranges. Check for pinout compatibility regarding the synchronous enable and multiplexed select pins.
