¬ Stand Alone 3D Bridge Chip for HD Sensors

Applications

¬

¬

¬

interfaces:

- four one-lane MIPI receiver for video

input

- can combine to dual 2-lane video input

- one channel two-lane MIPI transmitter

for video output

- up to 400 kHz SCCB with

13 MHz ~ 26 MHz input clock

- three general purpose IO (GPIO)

- one open drain output CMD_RDY

on-chip PLLs:

- system PLL - input clock frequency

ranges from 13 MHz to 26 MHz

- MIPI speed - 5x or 10x of system

clock for raw, 4x or 8x of system

clock for YUV

image signal processor (ISP)

- AEC/AGC/AWB

- two ISPs, one for each input video

stream

- max resolution: 1280 x 800

- max frame rate: 60 fps at 720p,

120 fps at VGA, 240 fps at QVGA

- defect pixel correction (DPC)

- lens shading correction (LENC)

SCCB:

- one SCCB master to control sensors

- one SCCB slave to take the

commands from host controller

- 7-bit SCCB slave device ID is fixed to

0x35 (0x6A for write, and 0x6B for

read)

- supports SCCB clock 100 kHz and

400 kHz

data format:

- input: raw

- output: raw 8/10-bit, YUV422

microcontroller:

- 8-bit microcontroller running at the

system clock

- 16 KByte program memory

power supply:

- 1.8V for DOVDD, 2.8V for MIPI and

PLL analog

- internal regulator generates 1.2V

DVDD from DOVDD for the digital

core circuit

- hardware standby mode: initiated by

pulling PWDN high, whole system

halts and input clock is gated

- software standby mode: initiated by

register, whole system except the

SCCB slave block halt
