GENERAL DESCRIPTION

The ICS8344I-01 is a low voltage, low skew fanout buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from IDT. The ICS8344I-01 has two selectable clock inputs. The CLKx, nCLKx pairs can accept most standard differential input levels. The ICS8344I-01 is designed to translate any differential signal level to LVCMOS/LVTTL levels. The low impedance LVCMOS/LVTTL outputs are designed to drive 50Ω series or parallel terminated transmission lines.
