Decoder extends mobile multimedia processor capability.
Press Release Summary:
Designed for use with MIPI CSI-1 and SMIA CCP2 class 0 serial interfaces, Model STCCP27A converts serial data stream from mobile phone's camera into parallel data for baseband processor. Device provides level shifting for bidirectional I2C control lines, allowing connection of 2.8 and 1.8 V I2C busses without external components. Housed in 3 x 3 mm micro-TFBGA25 package, RoHS-complaint video deserializer is capable of streaming full-resolution image data up to 416 Mbps.
Original Press Release:
STMicroelectronics' SMIA-Compatible Video De-Serializer for Camera Phones Extends Mobile Multimedia Processor Capability
ST Launches a CSI-1 / CCP2 Decoder Optimized for Mobile Phones, with I2C Level Shifting and a Miniature Package
GENEVA, June 13 -- STMicroelectronics (NYSE:STM), a world leader in CMOS image-sensor technology, has introduced the first video de-serializer 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 new interface IC, called the STCCP27A, connects a mobile phone'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 a mobile phone's camera into parallel data for its baseband processor. In addition, the device provides the necessary level shifting for the bidirectional I2C control lines, allowing the connection of 2.8V and 1.8V I2C busses without the need for external components.
The STCCP27A low-voltage high-speed serial interface decoder is capable of streaming full-resolution image data up to 416-Mbit/s. It consists of Sub-LVDS (Sub-Low Voltage Differential Signaling) receivers accepting serial data from the camera sensor, coupled with a shift-register-based internal decoder, which converts the pixel information to parallel data for the standard bus.
The CSI-1 and CCP2 class 0 high-speed serial video interface have only four wires and can be engineered to minimize electro-magnetic interference (EMI), enabling camera and receiver placement even close to radio areas; in clamshell mobile phone designs in particular, the new chip provides an ideal means of linking the camera to the processor with the minimum number of wires across the hinge, while minimizing noise generation caused by data moving through the parallel bus.
The STCCP27A facilitates the straightforward integration of these serial interfaces into a mobile application and can lead to system cost savings as EMI safeguards and flex circuit designs are simplified. Low pin count and the very small 3 x 3mm micro-TFBGA25 package comply with mobile-phone design constraints; power consumption in standby mode is only 10 microamps, maximum, leading to improved phone battery life.
ST plans to introduce a higher-frequency SMIA CCP2 Class 2 de-serializer interface covering up to a 650-Mbit/s data rate. Using configurable clock/strobe de-codification, it will cover all published SMIA classes, including 208-Mbit/s (CSI-1 / CCP2 Class 0) supported by the STCCP27A, the 416-Mbit/s (CCP2 Class 1) and 650-Mbit/s (CCP2 Class 2). Both devices are manufactured using ST's advanced sub-micron technology, which minimizes static and dynamic power consumption and is ideal for portable applications such as high-end mobile phones, PDAs, tablet PC, and other portable terminals.
Product is now available in final sample form in RoHS (Restriction of Hazardous Substances) compliant lead-free micro-TFBGA25 package needing just 9 square millimeters of printed wiring board area. Available now in volume production, the STCCP27A has US pricing of $1 in quantities of 1000 pieces.

Further information on MIPI and SMIA
The MIPI Alliance is a non-profit corporation that operates as an open membership organization. The common objective of MIPI members is to simplify the design and implementation of hardware and software by driving consistency in application processor interfaces, promoting reuse and compatibility in mobile devices. The CSI-1 is a serial interface adopted by the MIPI alliance as one of its legacy interfaces.
The SMIA standard is an open standard intended for use by all companies making, buying, or specifying miniature integrated camera modules for use in mobile applications, and is defined to allow designers to connect any SMIA- compliant sensor to any SMIA-compliant host system with matching capabilities to achieve a working system with good performance. SMIA was inaugurated in 2004 by STMicroelectronics and Nokia Corporation in response to the rapid growth of mobile camera phones and other mobile imaging devices, and has since been joined by other organizations.
