The 8344I-01 is a low voltage, low skew fanout buffer. The 8344I-01 has two selectable clock inputs. The CLKx, nCLKx pairs can accept most standard differential input levels. The 8344I-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. The effective fanout can be increased to 48 by utilizing the ability of the outputs to drive two series terminated lines. Redundant clock applications can make use of the dual clock inputs which also facilitate board level testing. The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertio
n of the clock enable pin. The outputs are driven low when disabled. The 8344I-01 is characterized at full 3.3V, full 2.5V and mixed 3.3V input and 2.5V output operating supply modes. Guaranteed output and part-to-part skew characteristics make the 8344I-01 ideal for those clock distribution applications demanding well defined performance and repeatability.
