Integrated Device Technology Low Skew,1-to-18 LVPECL-to-LVCMOS / LVTTL Fanout Buffer 83940DY-01LFT

The 83940-01 is a low skew, 1-to-18 LVPECL -to- LVCMOS / LVTTL Fanout Buffer. The 83940-01 has two selectable clock inputs. The PCLK , nPCLK pair can accept LVPECL , CML or SSTL input levels. The single ended clock input accepts LVCMOS or LVTTL input levels. The low impedance LVCMOS / LVTTL outputs are designed to drive 50ω series 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 83940-01 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 83940-01 ideal for those clock distribution applications demanding well defined performance and repeatability.
