MAX9150
The MAX9150 low-jitter, 10-port, low-voltage differential
signaling (LVDS) repeater is designed for applications
that require high-speed data or clock distribution while
minimizing power, space, and noise. The device
accepts a single LVDS input and repeats the signal at
10 LVDS outputs. Each differential output drives a total
of 50Ω, allowing point-to-point distribution of signals on
transmission lines with 100Ω terminations on each end.
Ultra-low 120ps (max) peak-to-peak jitter (deterministic
and random) ensures reliable communication in high-
speed links that are highly sensitive to timing error,
especially those incorporating clock-and-data recovery,
or serializers and deserializers. The high-speed switch-
ing performance guarantees 400Mbps data rate and
less than 100ps skew between channels while operat-
ing from a single +3.3V supply.
Supply current at 400Mbps is 160mA (max) and is
reduced to 60µA (max) in low-power shutdown mode.
Inputs and outputs conform to the EIA/TIA-644 LVDS
standard. A fail-safe feature sets the outputs high when
the input is undriven and open, terminated, or shorted.
The MAX9150 is available in a 28-pin TSSOP package.
Refer to the MAX9110/MAX9112 and MAX9111/MAX9113
data sheets for LVDS line drivers and receivers.

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.
