1:5 Differential LVPECL/LVECL/HSTL
Clock and Data Driver
General Description
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
by connecting the on-chip VBB supply to one input as a
reference voltage.
The MAX9315 features low output-to-output skew
(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.
The MAX9315 is offered in a space-saving 20-pin
TSSOP package.
