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 dissipation, and is mounted in a 24-pin ceramic package. The KGL4217 is used in high-speed optical communication 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.

KGL4217
10-Gbps GaAs Limiting Amplifier
Introduction
Oki Semiconductor’s KGL4217 Limiting Amplifier IC is designed for 10-Gbps digital communications
systems. This high speed, low-power Limiting Amplifier IC uses 0.2-µm gate length GaAs MESFET and
DCFL (Direct Coupled FET Logic) technologies. The KGL4217 is available as a 24-pin ceramic packaged
device. The high sensitivity of the KGL4217 requires capacitive coupling for input and output signal
interfaces.
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: 250 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
