SY100EP14UK4I

Clock Buffers, Drivers Overview

The SY100EP14UK4I is a high-speed, 2 GHz differential PECL/ECL 1:5 fanout buffer optimized for ultra-low skew applications. It features a 2:1 input multiplexer for redundant clock switchover and a synchronous enable pin to prevent runt clock pulses. The device operates with flexible supply voltages of 2.5V, 3.3V, or 5V and includes an internal VBB reference for single-ended or AC-coupled inputs. It supports LVPECL, PECL, ECL, LVECL, and HSTL logic levels within a 20-pin TSSOP package.

Clock Buffers, Drivers Feature Summary

• Guaranteed maximum frequency (fMAX) exceeding 2 GHz
• Within-device skew guaranteed to be less than 25 ps over temperature and voltage
• Integrated 2:1 differential input multiplexer for clock redundancy
• Synchronous enable pin (/EN) prevents runt clock pulse generation

Clock Buffers, Drivers Applications

• Redundant clock switchover systems
• Ultra-low skew clock distribution networks
• High-performance ECL system synchronization

Clock Buffers, Drivers Procurement Notes

Verify the industrial operating temperature range (-40°C to +85°C) required by the 'I' suffix against the application environment. Confirm that the 20-TSSOP package dimensions align with the PCB layout constraints. Ensure power supply decoupling capacitors are placed close to the VCC pins as specified in the datasheet recommendations.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:5 fanout ratio with integrated MUX functionality is required. It is suitable for systems needing direct interface with PECL, LVPECL, ECL, or HSTL signals without external resistor networks due to the built-in VBB reference. Consider part-to-part skew specifications if multiple buffers are used in parallel.

Clock Buffers, Drivers Part Context

This device belongs to Micrel's Precision Edge® and ECL Pro™ families of high-speed clock synchronization components. It is functionally compatible with industry-standard 100K ECL levels. The 'I' designation specifically denotes the industrial temperature grade variant within the SY100EP14U product line.

Clock Buffers, Drivers Replacement Considerations

The SY100EP14UK4C serves as the commercial temperature equivalent. For tape and reel packaging options, the SY100EP14UK4ITR is available. Verify lead-free status requirements; the SY100EP14UK4G series indicates Pb-Free compliance.
