Ultra-Low On-Capacitance and Return Loss to Support Data Rates Greater Than 2.7Gbps


Please check latest availability status for a specific part variant.

Description

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.
