1. Description

The LT86104SXE is Lontium’s 4rd generation 4-port HDMI/DVI splitter which can repeat one HDMI/DVI signal to 4 HDMI/DVI signal sets, support up to 4 different HDMI/DVI receiving/display terminals. Based on ClearEdge technology, it supports up to 3.4Gbps data rate per channel, compliant with the HDMI 1.4&DVI 1.0 specifications.
The device incorporates a pair of ODTs, an adaptive equalizer and a CDR circuit on each data channel of receiver side, and a de-emphasis driver with optional back terminations on each data channel of transmitter side. The clock channel feeds a high-performance PLL that regenerates a low jitter output clock for data recovery. The LT86104SXE process HDCP decryption/encryption and transmits the data to 4 HDMI/DVI ports.
The HDCP repeater engine in LT86104SXE handles all the processing required by authentication, decryption and encryption in hardware. This greatly reduces the external MCU overhead and firmware complexity. However, for more flexibility, the LT86104SXE also provides an option of software-controlled mode in which HDCP operations are entirely controlled by external MCU.
The LT86104SXE integrates EDID shadow RAM for better compatibility and reduced system complexity. Embedded EDID is accessible to the upstream port before the real EDID is loaded by the external MCU.
