SY100EL15LZC

Clock Buffers, Drivers Overview

The SY100EL15LZC is a low skew 1:4 clock distribution IC designed for Precision Edge applications. It operates on a 3.3V power supply and features multiplexed differential or single-ended ECL/PECL inputs. The device provides four differential clock outputs with an output-to-output skew of 50ps maximum. Key control signals include a synchronous enable (EN) and a clock select (SEL) input to switch between high-speed system clocks and lower speed scan/test clocks. Propagation delay ranges from 460ps to 700ps depending on the transition edge and input type.

Clock Buffers, Drivers Feature Summary

• Low skew 1:4 clock distribution with 50ps max output-to-output skew
• Multiplexed clock input supporting differential or single-ended ECL/PECL sources
• Synchronous enable/disable to prevent runt clock pulses
• Internal 75KΩ input pull-down resistors

Clock Buffers, Drivers Applications

• Low skew clock distribution networks
• High-speed system clock routing
• Scan or test clock distribution

Clock Buffers, Drivers Procurement Notes

Verify component authenticity through authorized channels as this is a specialized logic IC. Confirm RoHS compliance status, noting that Pb-Free variants exist under different suffixes. Check humidity sensitivity handling requirements during storage and assembly. Ensure the specific ZC suffix matches the commercial temperature range requirement for the target application.

Clock Buffers, Drivers Selection Notes

Select this component when a 3.3V ECL/PECL clock tree requires minimal skew across four branches. The synchronous enable feature is critical for systems needing glitch-free clock gating. Verify that the input signal swing meets the minimum 250mV requirement. Consider the 16-pin SOIC package constraints for PCB layout if space is limited.

Clock Buffers, Drivers Part Context

This part belongs to the SY100EL series of Precision Edge clock drivers. The 'Z' indicates a 16-pin SOIC package, while 'C' denotes the commercial temperature range (-40°C to +85°C). It is distinct from industrial variants like the SY100EL15LZI which share similar electrical characteristics but differ in temperature qualification.

Clock Buffers, Drivers Replacement Considerations

Direct replacements within the same family include SY100EL15LZI for industrial temperature ranges. For Pb-Free requirements, consider SY100EL15LZG. Ensure any substitute maintains the 1:4 fanout and low skew specifications required by the original design.
