SY100EL11VZG

Clock Buffers, Drivers Overview

The SY100EL11V is a 5V/3.3V ECL 1:2 differential fanout buffer manufactured by Microchip Technology. It operates with VCC ranging from 3.0V to 5.5V and VEE from -5.5V to 0V, supporting PECL and NECL logic families. The device features a typical propagation delay of 265 ps and within-device skew of 5 ps. Power supply current is typically 26 mA at +25°C. It includes internal 75 kΩ input pull-down resistors and clamping circuitry for open-input stability. The component is housed in an 8-pin SOIC package and functions as a non-inverting differential gate.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix when purchasing. The 'ZG' suffix indicates an 8-lead SOIC package with lead-free NiPdAu plating and a tube packaging quantity of 95 units. The '-TR' suffix denotes a tape and reel configuration containing 1,000 units per reel. Confirm package availability directly with Microchip sales offices if the tape and reel option is required.

Clock Buffers, Drivers Selection Notes

Select the SY100EL11V for designs requiring a single differential input split into two outputs with minimal timing variation. Ensure the power supply voltage aligns with the 3.0V to 5.5V range for PECL or -5.5V to 0V for NECL operation. Consider the 8-pin SOIC footprint for PCB layout. Verify that the thermal resistance and operating temperature range (-40°C to +85°C) meet system requirements.

Clock Buffers, Drivers Part Context
