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 Oki Semiconductor 1 s KGL4203 s ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– BLOCK DIAGRAM VDD D1 50 Ω D1R QN VDD VDD VDD D2 50 Ω D2R Q D1, D2 D1R, D2R Q, QN VDD Data Input Terminals Reference Voltage Terminals.
