KGL4216
10-Gbps GaAs T-Flip Flop IC
INTRODUCTION
Oki Semiconductor's KGL4216 is a 10-Gbps T-Flip Flop IC designed for ultra high-speed digital
communications systems. The KGL4216 uses 0.2-m gate length GaAs MESFETs and Oki's unique MCFF
( Memory Cell type Flip Flop ) technology to achieve operations of over 11-GHz. The KGL4216 is
available as a 24-pin ceramic packaged device. Due to the KGL4216's high sensitivity, capacitive
coupling is recommended for the KGL4216's I/O connections.
FEATURES
