General Description
The SY898530U is a 1:16 Fanout buffer which can accept
most standard differential logic levels and outputs the
signal as a differential 2.5V or 3.3V LVPECL signal. The
part can amplify input signals as small as 150mVpp to the
full LVPECL output swing. The SY898530U is well suited
for clock distribution applications which demand versatility
and low-skew performance. It is pin-to-pin compatible with
IDT’s ICS8530 fanout buffer.
The SY898530U operates from a 3.3V ±5% core power
supply and a 2.5V ±5% or a 3.3V ±5% output supply. The
SY898530U is guaranteed over the full commercial
temperature range (0°C to +70°C). It is available in a 48-
pin TQFP lead-free package.
