Overview
The DS90C387AVJD/NOPB is a Dual Pixel LVDS Display Interface / FPD-Link Transmitter produced by Texas Instruments. This component is designed to support dual pixel data transmission between a host and a flat panel display, supporting resolutions up to QXGA. It converts 48 bits of CMOS/TTL data (dual pixel 24-bit color) and 3 control bits into 8 LVDS (Low Voltage Differential Signalling) data streams, achieving a total throughput of 5.7 Gbps. This chipset is optimized for high-resolution flat panel applications, addressing EMI and cable size issues through its use of LVDS technology.
