ICS83947AYILN

Clock Buffers, Drivers Overview

The ICS83947AYILN is a low skew, 1-to-9 LVCMOS fanout buffer from the HiPerClockS family. It operates on a 3.3V supply and features nine LVCMOS/LVTTL outputs designed to drive 50 Ω series or parallel terminated transmission lines. The device supports selectable CLK0 and CLK1 inputs accepting LVCMOS or LVTTL levels, with a maximum output frequency of 110MHz. Key electrical parameters include a maximum output skew of 500ps and part-to-part skew of 2ns. It functions within an ambient temperature range of -40°C to 85°C.

Clock Buffers, Drivers Feature Summary

• Nine LVCMOS/LVTTL outputs for high-performance single-ended applications
• Selectable CLK0 and CLK1 inputs compatible with LVCMOS and LVTTL levels
• Maximum output frequency of 110MHz with guaranteed output skew of 500ps (max)
• Part-to-part skew limited to 2ns (max) for consistent timing across devices

Clock Buffers, Drivers Applications

• High-performance clock distribution in networking equipment
• Fanout buffering for LVCMOS/LVTTL logic systems
• Driving multiple loads via series or parallel terminated transmission lines

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm package type and lead-free status. The datasheet lists variants such as ICS83947IY, ICS83947IYL, ICS83947INLI, and ICS83947INLITR. Ensure the selected variant matches the required thermal management and packaging specifications for the target application environment.

Clock Buffers, Drivers Selection Notes

Select this component when driving up to nine LVCMOS or LVTTL loads with strict skew requirements. The effective fanout can be increased to 18 by utilizing the outputs' ability to drive two series terminated lines each. Ensure the design accommodates the 3.3V operating voltage and the specified -40°C to 85°C temperature range.
