The CS5262 is a high-performance DP1.4 to HDMI2.0b and VGA converter, designed to connect a DP1.4 source to an HDMI2.0b sink. The CS5262 integrates a DP1.4 compliant receiver, an HDMI2.0b compliant transmitter and a VGA output interface. The DP interface comprises 4 main lanes, AUX channel, and HPD signal. The receiver supports maximum 5.4Gbps (HBR2) data rate per lane. The DP receiver incorporates both HDCP1.4 and HDCP2.3 content protection scheme with embedded key for secure transmission of digital audio-video content. The HDMI interface includes 4 TMDS clock/data pairs, DDC, and HPD signal. The HDMI transmitter is capable of supporting up to 6Gpbs data rate, quite adequate for handling video resolutions up to FHD 1080p 120Hz and UHD 4k 60Hz formats. The HDMI transmitter incorporates HDCP engines which support both HDCP1.4 and HDCP2.3. With the inclusion of HDCP, the CS5262 allows secure transmission of protected content. Embedded key is available that provides the highest level of HDCP key security. The CS5262 is a highly integrated single chip suitable for multiple market segments and display applications, such as the dongle, docking station etc. DisplayPort 4 lanes DP RX HDMI TX MCU DMA SPI Billboard I2C Master I2C Slave HDCP1.4/2.3 RX PATTERN_G EN VGA TX HDCP1.4/2.3 TX HDMI VGA Figure 1-1 CS5262 Block Diagram Confidential
