KGL4203
10-Gbps GaAs EXOR/NOR IC
INTRODUCTION
Oki Semiconductor’s KGL4203 is a 10-Gbps GaAs EXOR/NOR IC designed for ultra high-speed digital
communications systems. The KGL4203 uses 0.2-µm gate length GaAs MESFETs and Oki’s unique DCFL
( Direct Coupled FET Logic ) technology to achieve operations of 10-GHz or more. The KGL4203 is
available as a 24-pin ceramic packaged device. Due to the KGL4203’s high sensitivity, capacitive
coupling is recommended for the interface.
FEATURES
• High-speed operation: 10-Gbps data rate (min)
• High sensitivity: 50 to 600 mVPP (at 10 Gbps 223 -1 PRPS, capacitive coupling)
• Low-power dissipation: 540 mW (typ.) using 2-V power-supply
• 0.2-µm gate length GaAs MESFET process
• DCFL (Direct Coupled FET Logic) technology
• 24-pin ceramic package
APPLICATION
• High-speed optical communication systems: 10 Gbps
• High-speed test equipment
