ICS83905AKT

PRELIMINARY Integrated Circuit Systems, Inc. ICS83905 LOW SKEW, 1:6 CRYSTAL INTERFACE-TOLVCMOS / LVTTL FANOUT BUFFER FEATURES 6 LVCMOS / LVTTL outputs Crystal oscillator interface Output frequency range: 10MHz to 50MHz Crystal input frequency range: 10MHz to 50MHz Output skew: 10ps (typical) 5V tolerant enable inputs Synchronous output enables Operating supply modes: Full 3.3V, 2.5V and 1.8V, mixed 3.3Vcore/2.5V or1.8V operating supply, and mixed 2.5V core/1.8V operating supply 0°C to 70°C ambient operating temperature Lead-Free package fully RoHS compliant Pin compatible to MPC905 Industrial version available upon request GENERAL DESCRIPTION The ICS83905 is a low skew, 1-to-6 LVCMOS / LVTTL Fanout Buffer and a member of the HiPerClockS™ HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS83905 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 6 to 12 by utilizing the ability of the outputs to drive two series terminated lines. ICS The ICS83905 is characterized at full 3.3V, 2.5V, and 1.8V, mixed 3.3V/2.5V, 3.3V/1.8V and 2.5V/1.8V output operating supply mode. Guaranteed output and part-to-part skew characteristics along with the 1.8V output capabilities makes the ICS83905 ideal for high performance, single ended applications that also require a limited outpu...
