CCD TOF Signal Processor with Programmable Timing and V-Driver

The ADDI9036 is a complete, 45 MHz, front-end solution for charge coupled device (CCD) time of flight (TOF) imaging applications. The ADDI9036 includes an analog front end (AFE), a programmable instruction set architecture (ISA) timing generator (ISATG), a 7-channel laser diode (LD) driver, a 7-channel H-driver, and a 16-channel vertical driver (V-driver). The Precision Timing® core allows adjustment of the CCD horizontal clocks and LD outputs with approximately 174 ps resolution at 45 MHz operation.

The AFE includes black level clamping, a correlated double sampler (CDS), a variable gain amplifier (VGA), and a 12-bit analog-to-digital converter (ADC). The AFE data is output through the MIPI® CSI-2 transmit interface.

The internal registers can be programmed by an I2C serial interface.

The ADDI9036 is packaged in a 6 mm × 6 mm, 117-ball WLCSP and is specified over an operating temperature range of −20°C to +85°C.
