1. General Description

LT8668SX can be configured to work under HDMI2.1 standard with maximum 8Gb/s data rate to allow for the highest resolutions of 8Kx4K 60Hz with DSC or 8Kx4K 30Hz.

LT8668SX also can be configured to work under DP1.4 with up to 8.1Gb/s data rate to allow for the highest resolutions of 8Kx4K 60Hz with DSC or 8Kx4K 30Hz.

For LVDS output, LT8668SX can be configured as single-port , dual-port or four-port LVDS with 1 high- speed clock lane, and 3~5 high-speed data lanes, which can support a total bandwidth up to 24Gbps.

For MIPI output, LT8668SX can be configured as single-port , dual-port or four-port MIPI with high-speed data lanes operating at maximum 2.5Gb/s/lane with D-PHY, which can support a total bandwidth of up to 40Gbps, Or support 5.7Gb/s/lane with C-PHY, which can support a total bandwidth of up to 68.4Gbps.

For eDP 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 3Gb/s per lane, which can support 4K@60Hz.

LT8668SX internally integrates an 8-bit OCM and SPI flash memory (stacked die) to run program. Online software upgrade is also supported for LT8668SX.

LT8668SX is fabricated in advanced CMOS process and implemented in 12mmx12mm BGA288 package. This package is RoHS compliant and specified to operate from -40°C to +85°C.
