Maxim MAX9390/MAX9391 Crosspoint Switches Datasheet
The MAX9390/MAX9391 are dual 2 x 2 crosspoint switches designed to perform high-speed, low-power, and low-noise signal distribution. These devices multiplex one of two differential input pairs to either or both low-voltage differential signaling (LVDS) outputs for each channel, supporting configurations such as a 2x2 crosspoint switch, 2:1 mux, 1:2 splitter, or dual repeater.
The MAX9390 provides high-level input fail-safe detection suitable for LVDS and HSTL inputs, while the MAX9391 offers low-level input fail-safe detection for LVPECL and CML inputs. Both devices operate up to 1.5GHz with ultra-low jitter, ensuring reliable communications in high-speed links sensitive to timing errors.

How can the LVDS outputs be enabled or disabled?
Each output pair is controlled by an EN pin; driving EN high enables the outputs, driving it low disables them.
