ICS8312

Integrated Circuit Systems, Inc. ICS8312 LOW SKEW, 1-TO-12 LVCMOS / LVTTL FANOUT BUFFER FEATURES 12 LVCMOS / LVTTL outputs LVCMOS / LVTTL clock input Maximum output frequency: 250MHz Output skew: 150ps (maximum) Operating supply modes: Core/Output 3.3V/3.3V, 2.5V/2.5V, 1.8V/1.8V, 3.3V/2.5V, 3.3V/1.8V, 2.5V/1.8V 0°C to 85°C ambient operating temperature Lead-Free package available Industrial temperature information available upon request GENERAL DESCRIPTION The ICS8312 is a low skew, 1-to-12 LVCMOS / LVTTL Fanout Buffer and a member of the HiPerClockS™ HiPerClockS™family of High Performance Clock Solutions from ICS. The ICS8312 single ended clock input accepts LVCMOS or LVTTL input levels. The low impedance LVCMOS outputs are designed to drive 50Ω series or parallel terminated transmission lines. The effective fanout can be increased from 12 to 24 by utilizing the ability of the outputs to drive two series terminated lines. www.DataSheet4U.com ICS The ICS8312 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 modes. Guaranteed output and part-to-part skew characteristics along with the 1.8V output capabilities makes the ICS8312 ideal for high performance, single ended applications that also require a limited output voltage.
