Overview
The DS90C241QVS/NOPB is a high-speed serializer component manufactured by Texas Instruments. It is part of the FPD-Link II family, designed to translate a 24-bit parallel bus into a fully transparent data and control LVDS serial stream with embedded clock information. This serialization simplifies the transfer of a 24-bit bus over PCB traces or cables, eliminating skew problems between parallel data and clock paths. The device is optimized for low-power and low-noise environments, making it reliable for serial data transmission. It is particularly suited for automotive applications due to its compliance with AEC-Q100 standards and its ability to operate over a wide temperature range of –40°C to 105°C.
