Overview
The DS90C241QVSX is a 24-bit FPD-Link II serializer produced by Texas Instruments (formerly National Semiconductor). This device is designed to translate a 24-bit parallel bus into a fully transparent data and control LVDS (Low-Voltage Differential Signaling) 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, and reduces system costs by minimizing the number of data paths, PCB layers, cable width, and connector size and pins.
The device operates within a temperature range of -40°C to 105°C and is compliant with the AEC-Q100 standard, making it suitable for automotive applications. It features LVDS signaling, which provides a low-power and low-noise environment for reliable data transfer over serial transmission paths.
