Low Skew, 1-to-9 LVCMOS Fanout Buffer 83947 Data Sheet GENERAL DESCRIPTION The 83947I is a low skew, 1-to-9 LVCMOS Fanout Buffer. The low impedance LVCMOS/LVTTL outputs are designed to drive 50Ω series or parallel terminated transmission lines. The effective fanout can be increased from 9 to 18 byutilizing the ability of the outputs to drive two series terminated lines. Guaranteed output and part-to-part skew characteristics make the 83947I ideal for high performance, single ended applications.

LVCMOS Fanout Buffer

Low Skew, 1-to-9 LVCMOS Fanout Buffer 83947 Data Sheet GENERAL DESCRIPTION The 83947I is a low skew, 1-to-9 LVCMOS Fanout Buffer. The low impedance LVCMOS/LVTTL outputs are designed to drive 50Ω series or parallel terminated transmission lines. The effective fanout can be increased from 9 to 18 byutilizing the ability of the outputs to drive two series terminated lines. Guaranteed output and part-to-part skew characteristics make the 83947I ideal for high performance, single ended applications that also require a limited output voltage. FEATURES • 9 LVCMOS/LVTTL outputs • Selectable CLK0 and CLK1 can accept the following input levels: LVCMOS and LVTTL • Maximum output frequency: 110MHz • Output skew: 500ps (maximum) • Part-to-part skew: 2ns (maximum) • 3.3V operating supply • -40°C to 85°C ambient operating temperature • Lead-Free package available BLOCK DIAGRAM ©2016 Integrated Device Technology, Inc PIN ASSIGNMENT GND Q2 VDDO Q1 GND Q0 VDDO GND 32 31 30 29 .
