8305I-02

Low Skew,1-to-4 Multiplexed Differential/LVCMOS-to-LVCMOS Fanout Buffer

Alternative Products
NOTICE - The following device(s) are recommended alternatives:
The 8305I-02 is a low skew, 1-to-4, Differential/LVCMOS-to-LVCMOS/LVTTL Fanout Buffer. The 8305I-02 has selectable clock inputs that accept either differential or single-ended input levels. The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/ deassertion of the clock enable pin. Outputs are forced LOW when the clock is disabled. A separate output enable pin controls whether the outputs are in the active or high impedance state.  Guaranteed output and part-to-part skew characteristics make the 8305I-02 ideal for those applications demanding well defined performance and repeatability

Features

  • Four LVCMOS/LVTTL outputs, (two banks of two LVCMOS outputs)
  • Selectable differential CLK, nCLK pair or LVCMOS_CLK input
  • CLK, nCLK pair can accept the following differential input levels: LVPECL, LVDS, LVHSTL, HCSL
  • LVCMOS_CLK supports the following input types: LVCMOS, LVTTL
  • Maximum output frequency: 250MHz
  • Output skew: 100ps (maximum)
  • Power supply modes:
    Core/Output
    3.3V/3.3V
    3.3V/2.5V
    3.3V/1.8V
    3.3V/1.5V
  • -40°C to 85°C ambient operating temperature
  • Lead-free (RoHS 6) packaging
