Tiny Image Sensor Integrates MDDI Interface

Debuting as the first 0.25", 3-Mpixel with a mobile display digital interface (MDDI), the OV3647 employs proprietary, 1.75-micron OmniPixel3 technology and also provides a standard parallel interface, which has the ability to act as an input for a secondary camera so it can share the MDDI interface while also functioning as an MDDI hub. This reduces the number of interconnects to the baseband processor, which increases reliability, reduces power consumption, and enables rapid two-way data transfers. Reportedly, sharing the MDDI also eliminates high-frequency EMI issues. The OV3647 is capable of operating at rates up to 15 fps at QXGA resolution. According to the company, it is small enough to enable 7 mm x 7 mm x 5 mm camera modules with a very short optical track and is versatile enough to work well with fixed focus and auto-focus modules. Available for sampling now, volume production begins in the third quarter. OMNIVISION TECHNOLOGIES INC., Sunnyvale, CA. (408) 542-3000.
