ICS83905AGT

Clock Buffers, Drivers Overview

The ICS83905AGT is a low skew, 1-to-6 LVCMOS/LVTTL fanout buffer from the HiPerClockS family. It features a crystal oscillator interface with an input frequency range of 10MHz to 40MHz and a maximum output skew of 80ps. The device supports full 3.3V, 2.5V, and 1.8V supply modes, as well as mixed core/output configurations (e.g., 3.3V core/1.8V output). It includes synchronous output enables, 5V tolerant enable inputs, and outputs capable of driving 50Ω series or parallel terminated transmission lines. The component operates within a 0°C to 70°C ambient temperature range.

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix 'T' corresponds to the specific tape-and-reel packaging configuration for this part number. Confirm the RoHS compliance status associated with the 'LF' designation if lead-free material is required for the assembly process. Ensure the selected package type matches the design constraints.

Clock Buffers, Drivers Selection Notes

Select based on the required output voltage level, choosing between full 3.3V, 2.5V, or 1.8V modes, or mixed core/output supplies. Verify that the crystal input frequency falls within the 10MHz to 40MHz range. Check thermal requirements against the junction-to-ambient thermal impedance values for the specific package and PCB layer count.
