SY100EP14UK4C

Clock Buffers, Drivers Overview

The SY100EP14UK4C 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 accepts PECL, LVPECL, ECL, LVECL, and HSTL logic inputs 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-speed data acquisition synchronization

Clock Buffers, Drivers Procurement Notes

Verify the commercial operating temperature range (-40 °C to +85 °C) matches system requirements. Confirm that the K4-20-1 20-pin TSSOP package footprint aligns with the PCB layout. Ensure power supply decoupling capacitors are placed close to the VCC pins as specified in the datasheet termination recommendations.

Clock Buffers, Drivers Selection Notes

Select this component when low propagation delay and minimal skew are critical. The integrated VBB reference simplifies biasing for single-ended inputs. Verify compatibility with the source logic family, as the device supports PECL, LVPECL, ECL, LVECL, and HSTL inputs directly.

Clock Buffers, Drivers Part Context

The SY100EP14U belongs to Micrel’s Precision Edge® and ECL Pro™ families of high-speed clock synchronization devices. The 'K4' suffix indicates the 20-pin TSSOP package type, while 'C' denotes the commercial temperature grade. This part is functionally equivalent to other variants in the SY100EP14 series differing only in packaging or temperature rating.
