670MHz, LVDS-to-LVDS and Anything-to-LVDS, 2:1 Multiplexers

Active: In Production.

The MAX9176/MAX9177 are 670MHz, low-jitter, low-skew, 2:1 multiplexers ideal for protection switching, loopback, and clock distribution. The devices feature ultra-low 68ps peak-to-peak deterministic jitter that ensures reliable operation in high-speed links that are highly sensitive to timing errors.

The MAX9176 has fail-safe LVDS inputs and an LVDS output. The MAX9177 has "anything" differential inputs (CML/LVDS/LVPECL) and an LVDS output. The output can be put into high impedance using the power-down input. The MAX9176 features fail-safe circuits that drive the output high when a selected input is open, undriven and shorted, or undriven and terminated. The MAX9177 has bias circuits that force the output high when a selected input is open. The mux select and power-down inputs are compatible with standard LVTTL/LVCMOS logic.

The select and power-down inputs tolerate -1V undershoot and V_CC + 1V overshoot. The MAX9176/MAX9177 are available in 10-pin µMAX and 10-pin thin QFN packages, and operate from a single 3.3V supply over the -40°C to +85°C temperature range.
