Four-Channel Stand-Alone MIPI Bridge Controller
for High Definition Multi-Camera Applications
OV680
lead free
available in
a lead-free
package
OmniVision's OV680 companion chip is a multi-sensor
bridge solution that combines images from four sensors
into a single data stream. Ideally suited for high
definition (HD) multi-camera applications, the OV680
has four 1-lane MIPI receivers for four video inputs or
two 2-lane MIPI for two video inputs, a 2-lane MIPI
transmitter for video output, and a built-in 8-bit
microcontroller.
The OV680 features integrated image signal processors
(ISPs), allowing it to process one, two, or four video
streams simultaneously. The companion chip can output
2x 720p video at 60 frames per second (fps), or 4x VGA
video at 120 fps.

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
