The OpenLDI transmitter (OLDITX) supports serialized RGB pixel data transmission between host and flat panel display over LVDS (Low Voltage Differential Sampling) interface. The LVDS interface complies with ANSI/TIA/EIA644-A standard (Electrical Characteristics of Low Voltage Differential Signaling (LVDS) Interface Circuits). The OLDITX consists of 7-to-1 data serializers, and 4-data and 1-clock LVDS outputs. The OLDITX translates 21 or 28-bit wide video/sync data into LVDS data, 3 or 4 bits wide and 7 bits deep. At a maximum pixel rate of 170 MHz, the speed of a single LVDS data lane is 1.19 Gbps providing a total throughput of 4.76 Gbps over a single OLDI link.
Figure 12-521 shows the high level overview of the OLDITX module.
