SY100EL33ZG

Overview

The SY100EL33ZG is a 3.3V ECL ÷4 divider integrated circuit manufactured by Microchip Technology. It operates within a power supply voltage range of 3.0V to 3.8V and supports toggle frequencies up to 4.2 GHz. The device features a typical propagation delay of 640ps from clock input to data output and 460ps from reset to output. It utilizes an asynchronous reset pin for synchronization and includes internal 75 kΩ input pull-down resistors. The component is housed in an 8-pin SOIC package and functions across an industrial temperature range of -40°C to +85°C.
