Features
Description
The STV0974 sensor interface is dedicated to the VS6552 image sensor that uses the VisionLink
data transfer protocol over vLVDS. This includes:
●
●
●
●
●
●
●
●
Low electromagnetic interference (EMI) interface with CMOS image sensors
High speed serial receiver, with data and clock inputs
Up to 120 Mbit/s operation using very low voltage differential signaling (vLVDS)
VisionLink transfer protocol
I²C compliant master controller, 1.8 V interface, up to 400 kHz operation
An I²C master controller supporting 1.8 V interface and 400 kHz operation. The I²C master port
signals are MSDA and MSCL that require external pull-up resistors. Internally, the I²C master is
a peripheral of the microprocessor control unit.
Two vLVDS receivers for sensor data and clock signals, PDATA and PCLK differential pairs
respectively. Each receiver accepts 1.8 V LVDS signals
A VisionLink data synchronization and extraction unit, which extracts image timing references,
active video and sensor status information. The extracted video stream in raw Bayer format
along with active video strobes are connected to the video processing unit. The sensor status
information is presented to the microprocessor control unit.
