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. FEATURES High-speed operation: 10-Gbps data rate (typ) Low-power dissipation: 340 mW (typ.) using 2-V power-supply 0.2-µm gate length GaAs MESFET process MCFF ( Memory Cell type Flip Flop ) technology 24-pin ceramic package APPLICATION High-speed optical communication systems: 10 Gbps High-speed test equipment Oki Semiconductor 1 s KGL4205 s ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– BLOCK DIAGRAM VDD VDD DA 50 Ω DR D D-Flip Flop (MCFF) Q D C VDD CK 50 Ω CR QN C VDD Q VDD Q DA CK DR, CR Q, QN VDD Data Input Terminals Clock Input Terminals Output Reference Voltage Terminals Complimentary Data Outputs Power Supply of Internal Circuit ELECTRICAL CHARACTERISTICS Absolute Maximum Ratings Parameter ...
