PS175 — DisplayPort™ to HDMI™ 2.0a
The PS175 is a DisplayPort™ (DP) to HDMI™ 2.0a video interface converter optimized for motherboard applications. It is designed to be used with a DP 1.2 or DP 1.3 input allowing it to output HDMI 2.0a up to the allowable maximum TMDS date rate of 6Gbit/sec, enabling 4K UHD video at 60 frames per second in 4:4:4 video mode at 24 bits-per-pixel.
The PS175 provides anonymous, automatic operation enabled by an integrated microprocessor that uses an internal SPI ROM for configuration and microcode. The SPI ROM can be field-updated through the DisplayPort AUX channel or device I2C slave input. System control is available through the I2C slave input, and an I2C master interface is available for external EDID and expansion functions. The PS175 fully supports both HDCP 1.4 and HDCP 2.3 content protection, including the HDCP repeater function, with integrated HDCP Rx & Tx keys.
