LT8668SX 龙迅发布 4K 高清显示控制器,内部没有集成LPDDR4 芯片

LT8668SX can be configured to work under HD-DVI2.1 receiver with maximum 10Gbps data rate and HD-DVI2.1 transmitter with maximum 12Gbps data rate.LT8668SX also can be configured to work under DP1.4a with up to 8.1Gbps data rate.For LVDS output, LT8668SX can be configured as single, dual or quad-port LVDS with 1 high-speed clock lane, and 3~5 high-speed data lanes, operating at maximum 1.2Gbps per lane, which can support a total bandwidth of up to 24Gbps. LT8668SX supports flexible video data mapping path for 2D and side by side 3D applications.For MIPI output, LT8668SX features configurable single-port or dual-port or quad-port MIPI®DSI/CSI with 1 high-speed clock lane and 1~4 high-speed data lanes operating at maximum 2.5Gbps per lane with D-PHY, which can support a total bandwidth of up to 40Gbps for four port. Also support 5.7Gbps per lane with C-PHY, which can support a total bandwidth of up to 68.4Gbps for four port.For eDP1.4 output, it consists of 8 data lanes, 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 eDPx output, it consists of 8 data lanes, with operating at maximum 3Gbps per lane, can support 4K@60Hz.Two digital audio output interfaces are available I2S and SPDIF. The I2S interface supports 8-ch LPCM and the SPDIF interface supports 2-ch LPCM or compressed audio, both at maximum 192 KHz sample rate.

The device is capable of automatic operation which is enabled by an integrated microprocessor that uses an embedded SPI flash for firmware storage. System control is also available through the configuration I2C slave interface.

LT8668SX is fabricated in advanced CMOS process and implemented in 12mmx12mm BGA288 package.

LT8668SX可以配置为在HD-DVI2.1下工作,最大数据速率为10Gbps, HD-DVI2.1发送器最大数据速率为12Gbps。




eDP1.4输出由8个数据通道组成,支持RBR (1.62Gbps)、HBR (2.7Gbps)和HBR2 (5.4Gbps)链路速度。内置可选的SSC功能,降低了对EMI相关系统应用的EMI影响。

对于eDPx输出,它由8个数据通道组成,每条通道最大运行速度为3Gbps,可以支持4K@60Hz。数字音频输出接口有I2S和SPDIF两种。I2S接口支持8-ch LPCM, SPDIF接口支持2-ch LPCM或压缩音频,最大采样率均为192 KHz。
