Abstract
The 8x8 Time Division Multiplexing (TDM) Switch ICs are designed to implement a building module of the switch fabric based on mailbox switch architecture. The proposed load-balanced mailbox switch can achieve ultra high speed switch capability with 8x8 TDM switch via recursive construction. An 8x8 TDM switch could be constructed recursively from the proposed switch module to achieve switching capacity of hundred gigabits per second or higher. There was an 8x8 TDM switch with serial input/output ports and embedded 8/10B CODECs for Ethernet application. A novel testing circuit was also implemented to easily verify switching result. Our results showed a 20 Gbps switching capacity for the 8x8 TDM switch with parallel input and output ports. All implementation were based on the 0.18μm CMOS technology.
