MAX4998 Datasheet | Maxim Integrated

19-5033; Rev 0; 10/09 .. Two-Lane and Four-Lane Display Port Passive Switches with Separate AUX/HPD Control General Description The MAX4998/MAX14998 high-speed passive switches route Display Port™ between two possible destinations or vice versa in laptops or desktop PCs. The MAX4998/ MAX14998 are intended to be used where ultra-highspeed 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 the one SPDT switch is for HPD. The two high-frequency switches are selected by SEL1, and the AUX and HPD are selected by SEL2. This part is suitable for two-lane Display Port 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 and HPD are selected by SEL2. This part is suitable for four-lane Display Port 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 -40NC to +85NC extended temperature range.
