General Description
The 83021I is a 1-to-1 Differential-to-LVCMOS/ LVTTL Translator
and a member of the family of High Performance Clock Solutions
from IDT. The differential input is highly flexible and can accept the
following input types: LVPECL, LVDS, LVHSTL, SSTL, and HCSL.
The small 8-lead SOIC footprint makes this device ideal for use in
applications with limited board space.
Features
