This complete camera module is ready to connect to the camera enabled baseband processor. Video data is output from the VL5510 over a 12-bit parallel interface and a high speed serial link (8/10/12 bits raw data output format supported on the compact camera port (CCP) interface compatible with an SMIA (standard mobile imaging architecture) normative. Control interface is an SPI (serial peripheral interface) or UART (universal asynchronous receiver transmitter) interface or I2C (Inter Integrated Circuit) interface. Power supplies delivered to the sensor are: ● 3.3 V for the analog blocks, ● 3.3 V for the digital interface, ● 2.5 V for the high speed serial link interface, ● 1.2 V for the internal digital core (generated internally using a low drop output regulator). The VL5510 is designed to operate in conjunction with an electronic central unit (ECU) that manages the device in the car. An input clock is required in the range 6 MHz to 27.77 MHz. The device contains an embedded video processor and delivers monochrome processed images at up to 34 frames per second. The video processor integrates a wide range of image enhancement functions, designed to ensure high image quality. These include: ● Antidark sun correction ● Dark calibration ● Vertical fix pattern correction ● Frame crop ● Defect pixel correction ● Test patterns generation ● Statistics generation (histogram) ● Sensor status data embedding (SCL, trailer) S 4/8 VL5510 2 Functional description Functional description The block diagram of the VL5510 is shown in Figure 1. VL5510 includes the following main blocks: ● Internal host (eWARP microcontroller): This is the internal host which is responsible for system operation sequencing and image data processing. It has the following features: – Safe system startup from hardware standby to software standby – System boot to drive it from software standby to streaming mode – System streaming soft stop – Device reinitialization to default mode (software reset) – High Dynamic mode setting (take in charge the management of the hardware knee point setting). ● ICB: Imager control block which contains all communication interfaces, transaction routings and resets and clock management ● IDP: Imager data pipeline which is responsible for real-time data processing at pixel clock rate. It implements a set of correction algorithms and dedicated block-IPs for data coding. ● CAB: Custom analog macro which contains the pixel array and all analog components that allow it to be driven. ● Data transmitters: Video data coders and transmitters, including serial and parallel interface. 5/8 Functional description Figure 1.
