Abstract :
An 8×8 and an expandable 16×16 crosspoint switch LSI utilizing a new circuit design and super self-aligned process technology (SST-1A) are discussed. The LSIs successfully switched with a bit error rate of less than 10-9 at 2.5 Gb/s using a 29-1 pseudorandom NRZ sequence. Pulse jitter was limited to less than 80 ps at 1.2 Gb/s by utilizing a small internal voltage swing (225 mV) employing a differential CML cell, including a selector. The LSIs have an ECL-compatible interface, -4-V and -2-V power supply voltages, and a power dissipation of less than 0.9 W for the 8×8 LSI and 2.8 W for the expandable 16×16 LSI
