Low-Jitter, 10-Port LVDS Repeater

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 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.
