» More than +20dBm Class C RF spectrum mask compliant with margins at MMCX antenna port.
» Superior fading sensitivity in the typical ETSI defined C2C multipath scenarios increases wireless
coverage.
» Internal 40MHz BW filter provides immunity to out-of-band radio interferences in multi-channel
operation.
» Dual DSRC PHY supports concurrent dual channel operation.
» Dedicated oscillator provides high frequency accuracy at ± 6.0ppm in –40ºC ~ +85ºC temperature
range.
» Dynamic and accurate power control in a wide 4.5dBm ~ 25dBm output range provides superior
performance stability.
» Integrated RF ESD protectors on antenna ports provide robust surge protection.
» High ESD protection design ensures immunity and robustness of all ports in ESD events. (IEC 61000-
4-2 Level 4, Contact ±8kV, Air ±15kV)
» 4-corner UV cured resin for BGA chips ensures vibrational and environmental reliability.
Performance:
» System on module design of Autotalks® Craton 3-CPU core communication processor, Pluton RF
transceiver, 128MB DDR3, and 32MB NOR enables V2X software applications on internal system, no
external CPU required.
» Automotive-grade -40ºC ~ +85ºC components and 50-pin header design secure environmental
reliability.
» Wide DC power input range from 6V ~ 40Vprovides application flexibility.
» Power management support of Idle, ON, and OFF state.
Subsystem:
» 50-pin header design provides feature rich I/O to meet connectivity requirement of V2X system
integration.
» Two on-board MMCX DIP antenna connectors provide robust RF performance up to 6GHz.
» Optional off-the-shelf hardware and software modules enable V2X OBU, V2X RSU, V2X Sensor
Fusion ECU applications.
