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.

The MAX9420MAX9423 are extremely fast, low-skew quad LVECL-to-LVPECL translators designed for highspeed signal and clock driver applications. The devices feature ultra-low propagation delay of 336ps and channel-to-channel skew of 17ps.

The four channels of MAX9420 can be operated synchronously with an external clock, or in asynchronous mode, determined by the state of the SEL input. An enable input provides the ability to force all the outputs to a differential low state.

These MAX9420 operate with a negative supply voltage of -2.0V to -3.6V, compatible with LVECL input signals.

The positive supply range of MAX9420 is 2.375V to 3.6V for differential LVPECL output signals.

A variety of input and output terminations are offered for maximum design flexibility. The MAX9420 has open inputs and open-emitter outputs. The MAX9421 has open inputs and 50 series outputs. The MAX9422 has 100 differential input impedance and open-emitter outputs. The MAX9423 has 100 differential input impedance and 50 series outputs.

The MAX9420MAX9423 are specified for operation from -40 to +85, and are offered in space-saving 32-pin 5mm * 5mm TQFP and 32-lead 5mm * 5mm QFN packages.
