Introduction
The NB3L208K is a differential 1:8 Clock fanout buffer
with High-speed Current Steering Logic (HCSL) outputs.
Inputs can directly accept differential LVPECL, LVDS and
HCSL signals. Single-ended LVPECL, HCSL, LVCMOS,
or LVTTL levels are accepted with a proper external V
reference supply. These signals will be translated to HCSL
and eight identical copies of Clock will be distributed,
operating up to 350 MHz.
This manual should be used in conjunction with the device
datasheet, which contains full technical details on the device
specifications and operation.
