1. General Description
LT8668SXK8-D can be configured to work under HDMI2.1 standard with maximum 8Gbps data rate.
LT8668SXK8-D also can be configured to work under DP1.4a with up to 8.1Gbps data rate.
For LVDS output, LT8668SXK8-D 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. LT8668SXK8-D supports flexible video data mapping path for 2D and side by side 3D applications.
For MIPI output, LT8668SXK8-D 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.
For video process, LPDDR controller is built-in and bandwidth up to 3733Mbps, support 2Gb x16 SDRAM organization.
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.
LT8668SXK8-D is fabricated in advanced CMOS process and implemented in 12mmx12mm BGA288 package.2
