Mini video deserializer fits SMIA- and MIPI-based camera phones

STMicroelectronics has introduced a video deserializer interface for use with MIPI CSI-1 and SMIA CCP2 Class 0 serial interfaces. The CSI-1 interface is part of the MIPI (Mobile Industry Processor Interface) standard and CCP2 Class 0 is part of the SMIA (Standard Mobile Imaging Architecture), the open standard for miniature camera modules.

The interface IC, called the STCCP27A, connects a mobile handset's camera module with its multimedia or baseband processor. Specifically, the device allows multimedia processors that have a legacy parallel interface to take advantage of the range of new attractive SMIA-compliant camera modules, which provide an output via the CCP serial interface.

The STCCP27A converts the serial data stream from the camera into parallel data for its baseband processor. In addition, the device provides the necessary level shifting for the bidirectional I2 C control lines, allowing the connection of 1.8- and 2.8-V I2 C buses without the need for external components.

The CSI-1 and CCP2 have only four wires and can be engineered to minimize electro-magnetic interference (EMI), enabling camera and receiver placement even close to radio areas. Samples are available in in RoHS-compliant lead-free micro-TFBGA25 packages. 1000-piece pricing is set at $1.00.
