DATA SHEET O K I G a A s P R O D U C T S KGL4205 10-Gbps D-Flip Flop IC 0.2µm Gate Length GaAs MESFET Technology February 2000 ■ ■ ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– Oki Semiconductor KGL4205 10-Gbps GaAs D-Flip Flop IC INTRODUCTION Oki Semiconductor’s KGL4205 is a 10-Gbps D-Flip Flop IC designed for ultra high-speed digital communications systems. The KGL4205 uses 0.2-µm gate length GaAs MESFETs and Oki’s unique MCFF ( Memory Cell type Flip Flop ) technology to achieve operations of 10-GHz or more. The KGL4205 is available as a 24-pin ceramic packaged device. Due to the KGL4205’s high sensitivity, capacitive coupling is recommended for IC’s DA and CK connections.
