Ps176 is a display port (DP) to HDMI 2.0 video interface converter, which is suitable for cable adapters, TV receivers, monitors and other applications requiring video protocol conversion. It will accept any display port input format, including DP 1.1a, dp1.2a, dp1.3, or dp1.4. It can output traditional HDMI and DVI video modes and HDMI 2.0 format. HDMI 2 is supported to the maximum allowable TMDs date rate of 6GB / s, so that 4K ultra-high image quality video can be played at the speed of 60 frames per second in the 4:4:4 video mode of 24 bits per second.

The ps176 can provide an integrated microprocessor for automatic configuration and microcode using an internal SPI ROM. SPI ROM can be updated in real time through display port auxiliary channel or I2C input device. System control can be input from I2C slave, and I2C master interface can be used for external EDID and extended functions. Both support hdco 1.4 and HDCP 2.2 content protection protocols and necessary HDCP regeneration functions, including HDCP repeater function and integrated HDCP receiving or transmitting function.

Cs5263 is a dp1.4 to HDMI 2.0, that is, dp1.4 to HDMI 4k60hz audio and video conversion chip. Cs5263 can be compatible with various parameters and functional characteristics of ps176. It is mainly used to design DP to hdmi2.0 audio and video converter or DP to HDMI 4k60hz audio and video adapter. It can also be used in the following products:

DisplayPort to HDMI active protocol converter

DisplayPort alt mode to HDMI protocol converter on USB type-C

Thunderbolt to HDMI protocol converter

HDMI output driver on docking station

Display port input on TV receiver

DisplayPort input on display

Cs5263 replaces ps176 parameter characteristics:


Integrated DisplayPort receiver and HDMI 2.0 transmitter for video format conversion

Support display resolution up to 4096 x 2160 at 60Hz frame rate, 24 bit color and 4:4:4 color sampling, and use 4-channel DP 1.2A, DP 1.3 or DP 1.4 input at HBr2 (5.4gbps) data rate

Jitter cleaning PLL provides stable HDMI output signal and wide compliance margin
