PS176 — DisplayPort to HDMI 2.0

The PS176 is a DisplayPort™ (DP) to HDMI™ 2.0 video interface converter ideal for cable adapters, television receivers, monitors, and other applications requiring video protocol conversion. It will accept any DisplayPort input format including DP 1.1a, DP 1.2a, DP 1.3, or DP 1.4.   It can output legacy HDMI and DVI video modes as well as the HDMI 2.0 format. HDMI 2.0 is supported 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 PS176 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 PS176 fully supports both HDCP 1.4 and HDCP 2.2 content protection, including the HDCP repeater function, with integrated HDCP Rx & Tx keys.
