Single/Dual/Triple/Quad DS3/E3/STS-1 LIUs

GENERAL DESCRIPTION The DS3251 (single), DS3252 (dual), DS3253 (triple), and DS3254 (quad) line interface units (LIUs) perform the functions necessary for interfacing at the physical layer to DS3, E3, or STS-1 lines. Each LIU has independent receive and transmit paths and a built-in jitter attenu
