MAX9316
The MAX9316 is a low-skew, 1-to-5 differential driver
designed for clock and data distribution. This device
allows selection between two inputs: one differential
and one single ended. The selected input is repro-
duced at five differential outputs. The differential input
can be adapted to accept a single-ended input by con-
necting the on-chip V
BB
supply to one input as a refer-
ence voltage.
The MAX9316 features low output-to-output skew
(20ps), making it ideal for clock and data distribution
across a backplane or board. For interfacing to differ-
ential HSTL and LVPECL signals, this device operates
over a +3.0V to +3.8V supply range, allowing high-per-
formance clock or data distribution in systems with a
nominal +3.3V supply. For differential LVECL operation,
this device operates with a -3.0V to -3.8V supply.
The MAX9316 is offered in a space-saving 20-pin
TSSOP and wide-body SO package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Measurements are made with the device in thermal equilibrium.
Current into a pin is defined as positive. Current out of a pin is defined as negative.
DC parameters are production tested at T
A
= +25°C and guaranteed by design over the full operating temperature range.
Use V
BB
only for inputs that are on the same device as the V
BB
reference.
All pins are open except V
CC
and V
EE
.
Guaranteed by design and characterization. Limits are set at ±6 sigma.
Measured between outputs of the same part at the signal crossing points for a same-edge transition.
Measured between outputs of different parts at the signal crossing points under identical conditions for a same-edge transition.
Device jitter added to a jitter-free input signal.
