Package: LQFP 32 Type

Manufacturer: Integrated Device Technology


ICS83940-02 datasheet



The ICS83940-02 is a low skew, 1-to-18 Fanout Buffer . The 83940-02 has two selectable clock inputs. The CLK0, nCLK0 pair can accept most standard differential input levels. The single ended clock input accepts LVCMOS or LVTTL input levels. The low impedance LVCMOS/LVTTL outputs are designed to drive 50Ωseries or parallel terminated transmission lines. The effective fanout can be increased from 18 to 36 by utilizing the ability of the outputs to drive two series terminated lines.

The ICS8394002 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 ICS83940 ideal for those clock distribution applications demanding well defined performance and repeatability.
