MAX9402EHJ+T

P1-P3P4-P6P7-P9P10-P12P13-P13
General Description
The MAX9400/MAX9402/MAX9403/MAX9405 are
extremely fast, low-skew quad LVECL/ECL or LVPECL/
PECL buffer/receivers designed for high-speed data
and clock driver applications. These devices feature an
ultra-low propagation delay of 335ps and channel-to-
channel skew of 16ps in asynchronous mode with
86mA supply current.
The four channels can be operated synchronously with
an external clock, or in asynchronous mode determined
by the state of the SEL input. An enable input provides
the ability to force all the outputs to a differential low
state.
A variety of input and output terminations are offered for
maximum design flexibility. The MAX9400 has open
inputs and open emitter outputs. The MAX9402 has
open inputs and 50Ω series outputs. The MAX9403 has
100Ω differential input impedance and open emitter
outputs. The MAX9405 has 100Ω differential input
impedance and 50Ω series outputs.
These devices operate with a supply voltage of (V
CC
-
V
EE
) = 2.375V to 5.5V, and are specified for operation
from -40°C to +85°C. These devices are offered in
space-saving 32-pin 5mm ✕ 5mm TQFP and 32-lead
5mm ✕ 5mm QFN packages.

Note 1: Measurements are made with the device in thermal equilibrium.
Note 2: Current into a pin is defined as positive. Current out of a pin is defined as negative.
Note 3: DC parameters are production tested at +25°C. DC limits are guaranteed by design and characterization over the full oper-
ating temperature range.
Note 4: Guaranteed by design and characterization. Limits are set to ±6 sigma.
Note 5: Measured between outputs of the same part at the signal crossing points for a same-edge transition.
Note 6: Device jitter added to the input signal.
