KGL4222
10-Gbps GaAs 1:16 Demultiplexer Integrated Circuit
INTRODUCTION
Oki Semiconductor’s KGL4222 is an 10-Gbps GaAs 1:16 demultiplexer IC that converts a single, serial
data stream into 16-bit parallel data operating with a maximum clock frequency of over 10 GHz. The
high-speed KGL4222 is manufactured using Oki’s 0.2-µm gate length GaAs MESFET process, and is
mounted in a 48-pin package. By using Oki’s unique MCFF (Memory Cell Flip Flop) and CBFF (Com-
mon-gate Bias Flip Flop) technology, the KGL4222 provides high-speed operation and low power dissi-
pation. External capacitive coupling is required for clock input and data output connections. Low speed
signal interfaces are compatible with ECL.
