Contributing to ADAS low-power consumption and EMC achievement
Rohm announced on the 1st the development of the SerDes IC 'BU18xMxx-C' and PMIC 'BD86852MUF-C' for advanced driver assistance system (ADAS) camera modules. Both products address the challenges of miniaturization and low-power consumption in modules, and with low electromagnetic emissions, they facilitate EMI management.

The BU18xMxx-C SerDes IC can optimize transmission speed according to resolution, enabling 27% lower power consumption compared to general products in applications using four camera modules. Additionally, by applying transmission speed optimization and spectrum spreading function, the maximum EMI was reduced by 20dB. It also provides a sticking detection function that detects video freezing.
The BD86852MUF-C camera PMIC can manage the power systems of CMOS image sensors from major manufacturers. As a single IC, voltage setting and sequence control are possible, reducing mounting area by 41%. Additionally, by externally configuring the LDO for power supply and dispersing heat concentration on the camera PMIC, heat generation has been suppressed, achieving 78.6% conversion efficiency.
Both products conform to AEC-Q100. The BU18xMxx-C SerDes IC began sample shipments from February of this year at 1,000 yen per unit (excluding tax), and mass production of 200,000 units per month commenced this month. The BD86852MUF-C PMIC has been in mass production at 500,000 units per month since January of this year. The sample price is 500 yen (excluding tax). Rohm is currently developing a camera PMIC that supports ISO 26262 certification, and plans to ship samples of products conforming to ASIL-B safety level with the same specifications as the BD86852MUF-C PMIC within this year.

Will C-V2X surpass DSRC and become the cornerstone of autonomous driving infrastructure?
The United States has adopted C-V2X as the single standard for next-generation V2X technology and will implement it from July onwards. The DSRC method, which has occupied the 5.9GHz band frequency for over 20 years, will be gradually phased out. With the confirmation of C-V2X as a single standard, there are calls for South Korea to promptly select the C-V2X standard and establish the industry ecosystem at an early stage in order to respond to the U.S. market, the country's largest automotive export market.
