SNLS605C July 2018 – April 2024 DS90UB935-Q1
PRODUCTION DATA
The DS90UB935-Q1 serializes data from high-resolution image sensors or other sensors using the MIPI CSI-2 interface. The DS90UB935-Q1 serializer is optimized to interface with the DS90UB936-Q1 or DS90UB954-Q1 deserializer (dual hub), the DS90UB960-Q1 deserializer (quad hub), the DS90UB934-Q1 and DS90UB914A-Q1 deserializers, as well as other potential future deserializers. The interconnect between the serializer and the deserializer can be either a coaxial cable or shielded-twisted pair (STP) cable. The DS90UB935-Q1 was designed to support multi-sensor systems such as surround view, and as such has the ability to synchronize sensors through the DS90UB936-Q1, DS90UB954-Q1, and DS90UB960-Q1 hubs.
The DS90UB935-Q1 serializer and companion deserializer incorporate an I2C-compatible interface. The I2C-compatible interface allows programming of serializer or deserializer devices from a local host controller. In addition, the devices incorporate a bidirectional control channel (BCC) that allows communication between the serializer and deserializer, as well as between remote I2C target devices.
The bidirectional control channel (BCC) is implemented through embedded signaling in the high-speed forward channel (serializer to deserializer), combined with lower speed signaling in the reverse channel (deserializer to serializer). Through this interface, the BCC provides a mechanism to bridge I2C transactions across the serial link from one I2C bus to another.
