Silicon Line unveils the world’s first MIPI M-PHY optical media converter ICs for mobile phones
The ICs are used to optically connect cameras, displays and application processors and enable the replacement of traditional electrical connectors with optical connectors.
Strong consumer demand for full HD video cameras, 3D cameras, high resolution and 3D displays is driving the data rates inside a phone ever higher. The high data rates not only generate EMI when traditional electrical cables are used to transport the data but also are reaching the limits of the capabilities of electrical cables. Recognizing these challenges, the standard creating organization within the mobile phone industry, the MIPI Alliance, has defined a high speed physical layer called M-PHY and has created a standard for how to transport M-PHY signals optically.
Silicon Line already has a broad portfolio of ultra-low power high speed optical link interface ICs including products for MIPI D-PHY based mobile phones. The SL82027 and SL82017 are the latest additions to the portfolio and are the first products compliant with the M-PHY specification.
“The latest generation of Full HD / 3D camera modules demand the extremely high data rates which M-PHY provides”, said Ian Jackson, Senior Manager Sales and Marketing at Silicon Line. “Optical transport of these signals solves the EMI challenges which these data rates create as well as enabling small and thin form factor designs”, he added. An SL82027 and SL82017 based OMC can be used to connect an application processor to a camera module in order to transmit high speed image data to the application processor using the future MIPI Alliance CSI-3 (Camera Serial Interface) standard. Such an OMC can also be used to transmit image data from the application processor to the display using the future MIPI next generation display interface standard.
The SL82027 vertical cavity surface emitting laser (VCSEL) driver and the SL82017 transimpedance amplifier (TIA) together with appropriate photonics are used to implement a MIPI compliant Basic OMC for transporting M-PHY signals. Both devices include special circuits which handle the M-PHY specific protocol and process both the high speed and low speed signals. Data transmission is done optically over a fiber in the case of high speed data and low speed data is transmitted over an auxiliary galvanic interconnect.
The devices support both the MIPI M-PHY defined low speed PWM-BURST mode up to PWM Gear 7 and also the high speed HS-BURST mode up to Gear 2. The ultra-low power consumption of the SL82027 and the SL82017 make them ideally suited for use within mobile phones and smart phones.
The SL82027 and SL82017 are available as bare die and are sampling now.
