The Lontium LT9721 is MIPI/HDMI to DP converter with internal Type-C Alternate Mode switch and PD controller.
For MIPI DSI® input, LT9721 features a single-port MIPI DSI receiver with 1 clock lane and 4 data lanes operating at maximum 1.5Gbps per data lane and a maximum input bandwidth of 6Gbps. The converter decodes the input 18/24-bit RGB packets and converts the formatted video data stream to a 4-lane DP1.2 compliant output, supporting RBR(1.62Gbps), HBR(2.7Gbps) and HBR2(5.4Gbps) link speeds. The build-in optional SSC function reduces EMI effect on EMI-concerned system application.
For HDMI input, LT9721 features a HDMI1.4 receiver with 1 clock lane and 3 data lanesoperating at maximum 3.4Gbps per data lane and a maximum input bandwidth of 10.2Gbps, allowing resolution up to 4Kx2K@30Hz for RGB format and 4Kx2K@60Hz for YUV420 format. The converter also integrates a DDC controller and supports HDCP1.4.
In order to be adaptable to the latest USB Type-C ecosystem, LT9721 integrates a high performance bi-directional passive differential switch controlled by CC logic and PD management unit to releive mobile system design complexity and BOM cost. The switch function is compliant with VESA DP Alternate Mode on USB Type-C Standard.
The LT9721 is fabricated in advanced CMOS process and implemented in a small outline 5mm x 5mm BGA81 (LT9721-B81) and 7.5mm x 7.5mm QFN64 (LT9721-Q64) package. This package is RoHS compliant and specified to operate from -40°C to +85°C.
