KGL4217/KGL4221/KGL4222
10-Gbps GaAs Optical Communications Family Products
INTRODUCTION
Oki Semiconductor’s 10-Gbps GaAs Optical Communications Family Products include the KGL4217
Limiting Amplifier, KGL4221 16:1 Multiplexer IC, andKGL4222 1:16 Demultiplexer IC. These 10-Gbps
optical devices are manufactured using Oki Semiconductor’s 0.2-µm gate length GaAs MESFET process.
The KGL4217 Limiting Amplifier provides high-speed operation, high-sensitivity, low power dissipa-
tion, and is mounted in a 24-pin ceramic package. The KGL4217 is used in high-speed optical communi-
cation environments operating with a maximum clock frequency of over 10 GHz.
The KGL4221 Mux and KGL4222 Demux feature high-speed operation and low power dissipation, and
they are mounted in a 48-pin package. These ICs that provide high-speed conversion of parallel-to-serial
(demux) or serial-to-parallel (mux) data streams operating with a maximum clock frequency of over 10
GHz.
