MAX9400

The MAX9400/MAX9402/MAX9403/MAX9405 are extremely fast, low-skew quad LVECL/ECL or LVPECL/PECL buffer/receivers designed for high-speed data and clock driver applications. These devices feature an ultra-low propagation delay of 335ps and channel-to-channel skew of 16ps in asynchronous mode with 86mA supply current.

The four channels 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.

A variety of input and output terminations are offered for maximum design flexibility. The MAX9400 has open inputs and open emitter outputs. The MAX9402 has open inputs and 50Ω series outputs. The MAX9403 has 100Ω differential input impedance and open emitter outputs. The MAX9405 has 100Ω differential input impedance and 50Ω series outputs.

These devices operate with a supply voltage of (V_CC - V_EE) = +2.375V to +5.5V, and are specified for operation from -40°C to +85°C. These devices are offered in space-saving 32-pin 5mm x 5mm TQFP and 32-lead 5mm x 5mm QFN packages.
