Overview
The DS90UB940-Q1, produced by Texas Instruments, is a 1080p FPD-Link III to CSI-2 deserializer. This device is designed to convert 1-lane or 2-lane FPD-Link III serial streams into a MIPI CSI-2 format, supporting video resolutions up to WUXGA and 1080p60 with 24-bit color depth. It is AEC-Q100 qualified, ensuring robust performance in automotive and other demanding environments, with an ambient operating temperature range of –40°C to +105°C. The deserializer integrates video and audio data transmission along with full duplex control, including I2C and SPI communication, over the same differential link, thereby reducing interconnect size and weight and simplifying system design.
