Lontium LT9721是MIPI / HDMI到DP轉(zhuǎn)換器，帶有內(nèi)部Type-C交替模式開(kāi)關(guān)和PD控制器。
對(duì)于MIPIDSI?輸入，LT9721具有單端口MIPI DSI接收器，具有1個(gè)時(shí)鐘通道和4個(gè)數(shù)據(jù)通道，每個(gè)數(shù)據(jù)通道最大1.5Gbps，最大輸入帶寬為6Gbps。轉(zhuǎn)換器對(duì)輸入的18/24位RGB數(shù)據(jù)包進(jìn)行解碼，并將格式化的視頻數(shù)據(jù)流轉(zhuǎn)換為4路DP1.2兼容輸出，支持RBR（1.62Gbps），HBR（2.7Gbps）和HBR2（5.4Gbps）鏈路速度。內(nèi)置可選的SSC功能可降低EMI對(duì)系統(tǒng)應(yīng)用的影響。
對(duì)于HDMI輸入，LT9721具有1個(gè)時(shí)鐘通道的HDMI1.4接收器和3個(gè)數(shù)據(jù)通道，每個(gè)數(shù)據(jù)通道最大3.4Gbps，最大輸入帶寬為10.2Gbps，RGB格式的分辨率高達(dá)4Kx2K @ 30Hz，60Hz為4Kx2K YUV420格式。該轉(zhuǎn)換器還集成了DDC控制器并支持HDCP1.4。
為了適應(yīng)最新的USB Type-C生態(tài)系統(tǒng)，LT9721集成了由CC邏輯和PD管理單元控制的高性能雙向無(wú)源差分開(kāi)關(guān)，以降低移動(dòng)系統(tǒng)設(shè)計(jì)復(fù)雜性和BOM成本。開(kāi)關(guān)功能符合USB Type-C標(biāo)準(zhǔn)的VESA DP備用模式。
LT9721采用先進(jìn)的CMOS工藝制造，采用小尺寸5mm x 5mm BGA81（LT9721-B81）和7.5mm x 7.5mm QFN64（LT9721-Q64）封裝。該封裝符合RoHS標(biāo)準(zhǔn)，額定工作溫度范圍為-40°C至+ 85°C。

1.Description
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.
