Overview
The STLVDS385BTR, produced by STMicroelectronics, is a +3.3 V programmable LVDS (Low Voltage Differential Signaling) transmitter designed for 24-bit flat panel display (FPD) links. This integrated circuit converts 28 bits of LVCMOS/LVTTL data into four LVDS data streams and a phase-locked transmit clock, transmitted over a fifth LVDS link. It supports a wide range of display resolutions including VGA, SVGA, XGA, and single/dual pixel SXGA. The device is optimized for low power consumption and reduced electromagnetic interference (EMI), making it suitable for various display applications.
