Datasheet
1.MAX9321AEUA-T.pdf (9 pages)
The MAX9321/MAX9321A are low-skew differential
receiver/drivers designed for clock and data distribu-
tion. The differential input can be adapted to accept a
single-ended input by connecting the on-chip V
ply to an input as a reference voltage.
The MAX9321/MAX9321A feature ultra-low propagation
delay (172ps) and part-to-part skew (20ps) with 24mA
maximum supply current, making these devices ideal
for clock buffering or repeating. For interfacing to differ-
ential HSTL and LVPECL signals, these devices oper-
ate over a +2.25V to +3.8V supply range, allowing
high-performance clock and data distribution in sys-
tems with a nominal +2.5V or +3.3V supply. For differ-
ential LVECL operation, these devices operate from a
-2.25V to -3.8V supply. Multiple pinouts are provided to
simplify routing across a backplane to either side of a
double-sided board.
Both devices are offered in space-saving 8-pin SOT23,
SO, and µMAX packages.
19-2152; Rev 2; 11/02
