DisplayPort to HDMI 2.0a converter ICs with on-chip jitter cleaning

Parade Technologies has added two new ICs PS175 and PS176 to convert the video output data format from DisplayPort 1.2a or DisplayPort 1.3 to HDMI 2.0a interface standard. The PS175 converter chip is for use in mother board applications in portable and desktop systems, where as PS176 is designed for protocol adapters or “dongles”, including DisplayPort Alt Mode over USB Type-C to HDMI 2.0a adapters. 4K UHD performance at 60fps and 24 bits-per-pixel color with 4:4:4 color sampling video quality is supported by both PS175 and PS176 with the ability to handle HDMI 2.0a data rate of 6Gbit/sec. These chips can take DP 1.2a or DP 1.3 input of 4 lanes at the HBR2 (5.4Gbit/sec) link rate. HDCP 1.4 and HDCP 2.2 content protection is provided for both the DisplayPort input and HDMI output, along with the necessary HDCP repeater functionality. Internal conversion to 4:2:0 HDMI output format is provided, as is the ability to handle 8 channels of 24-bit audio at a 192kHz sample rate. Both these chips clean up the jitter, which includes jitter ingress and ISI generated jitter from the DisplayPort transmission line during the protocol conversion process. Parade assure to get a low-jitter HDMI 2.0a output with generous compliance margin even at the 6Gbit/sec HDMI 2.0a data rate. This jitter cleaning feature enables use of longer cable also a less quality cable. “Many semiconductor v...
