MAX14998, MAX4998双通道和四通道Displa
max14998, max4998双通道和四通道displayport无源开关，具有独立的aux/hpd控制
概述
the max4998/max14998 high-speed passive switches route displayport™ between two possible destinations or vice versa in laptop or desktop pcs. the max4998/max14998 are intended to be used where ultra-high-speed performance and minimal input capacitance is required.
the max4998 has three double-pole/double-throw (dpdt) switches and one single-pole/double-throw (spdt) switch. two dpdt switches are for high-frequency switching, one dpdt switch is for aux, and one spdt switch is for hpd. the two high-frequency switches are selected by sel1, and the aux/hpd are selected by sel2. this part is suitable for two-lane displayport switching.
the max14998 has six double-pole/double-throw (dpdt) switches. four dpdt switches are for high-frequency switching, and two dpdt switches are for aux and hpd. the four high-frequency switches are selected by sel1, and the aux/hpd are selected by sel2. this part is suitable for four-lane displayport switching.
the max4998/max14998 are fully specified to operate from a single +3.3v (typ) power supply. the max4998 is available in a 3.5mm x 5.5mm, 28-pin tqfn package with exposed pad, and the max14998 is available in a 3.5mm x 9mm, 42-pin tqfn package with exposed pad. both devices operate over the -40°c to +85°c extended temperature range.
关键特性
