Overview
The DS90C363BMT/NOPB is a +3.3V programmable LVDS (Low Voltage Differential Signaling) transmitter designed by Texas Instruments. This device is specifically tailored for Flat Panel Display (FPD) links, converting 21 bits of CMOS/TTL data into three LVDS data streams along with a phase-locked transmit clock. It operates within a wide temperature range of -10°C to +70°C, making it suitable for various environmental conditions. The DS90C363BMT/NOPB is packaged in a 48-pin TSSOP (Thin Shrink Small Outline Package) and is RoHS compliant, ensuring it meets environmental sustainability standards.
