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.
