Overview
The DS90C387VJDX/NOPB, produced by Texas Instruments, is a +3.3V Dual Pixel LVDS Display Interface (LDI) transmitter designed to support dual pixel data transmission between a host and a flat panel display. This component is part of the DS90C387/DS90CF388 transmitter/receiver pair, which complies with the OpenLDI Specification for digital display interfaces up to QXGA resolutions.
It converts 48 bits of CMOS/TTL data (24-bit color for dual pixels) into 8 LVDS data streams, along with control signals such as VSYNC, HSYNC, DE, and two user-defined signals sent during blanking intervals. This chipset is ideal for solving EMI and cable size problems in high-resolution flat panel display applications.
