Oki Electric Industry KGL4205
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.FEATURES
