General Description

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 high­speed links that are highly sensitive to timing error,
especially those incorporating clock-and-data recovery,
or serializers and deserializers. The high-speed switch­ing performance guarantees 400Mbps data rate and
less than 100ps skew between channels while operat­ing 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.
