The MAX9315 low-skew, 1-to-5 differential driver is
designed for clock and data distribution. This device
allows selection between two inputs. The selected input
is reproduced at five differential outputs. The differential
inputs can be adapted to accept a single-ended input
♦ +2.375V to +3.8V Supply for Differential
HSTL/LVPECL Operation
♦ -2.375V to -3.8V Supply for Differential LVECL
Operation
by connecting the on-chip V supply to one input as a
reference voltage.

♦ Two Selectable Differential Inputs
♦ Synchronous Output Enable/Disable
♦ 20ps Output-to-Output Skew
The MAX9315 fe a ture s low outp ut-to-outp ut s ke w
(20ps), making it ideal for clock and data distribution
across a backplane or a board. For interfacing to differ-
ential HSTL and LVPECL signals, this device operates
over a +2.375V to +3.8V supply range, allowing high-
performance clock or data distribution in systems with a
nominal +2.5V or +3.3V supply. For differential LVECL
operation, this device operates with a -2.375V to -3.8V
supply.
♦ 360ps Propagation Delay
♦ Guaranteed 400mV Differential Output at 1.5GHz
♦ On-Chip Reference for Single-Ended Inputs
♦ Input Biased Low when Left Open
♦ Pin Compatible with MC100LVEP14
The MAX9315 is offe re d in a s p a c e -s a ving 20-p in
TSSOP package.
