GENERAL DESCRIPTION
The ICS8525 is a low skew, high performance 1-to-4 LVCMOS-to-LVHSTL fanout buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS8525 has two selectable clock inputs that accept LVCMOS or LVTTL input levels and translate them to 1.8V LVHSTL levels. The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin.

FEATURES
• 4 differential 1.8V LVHSTL outputs
• Selectable LVCMOS / LVTTL clock inputs for redundant and multiple frequency fanout applications
• Maximum output frequency up to 266MHz
• Translates LVCMOS and LVTTL levels to 1.8V LVHSTL levels
• Output skew: 35ps (maximum)
• Part-to-part skew: 150ps (maximum)
• Propagation delay: 1.9ns (maximum)
• 3.3V core, 1.8V operating supply
• 0°C to 70°C ambient operating temperature
• Industrial temperature information available upon request
