0.18μm CMOS, Monolithic MSTP ASIC

I. Introduction Motivated by adopting both telecom and data-com traffic into Synchronous Digital Hierarchy (SDH)[1] transport payloads, we develop the mono-lithic Multi-Service Transport Platform (MSTP)[2] Application Specified Integrated Circuit (ASIC) MSEOSX8-6, which is a highly integrated device capable of mapping 10/100/1000Mbit/s Ethernet[3], 155Mbit/s Resilient Packet Ring (RPR)[4], as well as 2.048Mbit/s E1 traffic into SDH STM-1 payloads. On the line side, the chip s…
