The AK1553 is a 5.9GHz RF Transceiver with PA for ETC 2.0 System.
2016-05-13 | Return
Product Name AK1553, AK1553EProduct: Analog Front End & RF > Short Range RF IC
Title 5.9GHz RF Transceiver
Applications Automotive ETC (Electronic Toll Collection) Devices
Description
The ministry of Land, Transport and Tourism of Japan has announced that accidents and traffic jam information as well as the best time route assist service will be provided in the ETC 2.0* system. This system is expected to be expanding as a part of ADAS (Advanced Driver Assistance System) for a safe and ecological car society.
Asahi Kasei Microdevices Corporation (AKM) has developed the AK1553 series RF transceivers for ETC systems using AKM's integration technique and design knowledge of radio frequency analog circuits. The AK1553 and AK1553E have optimized characteristics for ETC products while needing less external parts because of its integrated RF amplifiers. The AK1553 for ETC 2.0 and the AK1553E for ETC 1.0 systems allow system designers to support either ECT system.
* ETC 2.0 is the world first driver supporting service via a vehicle infrastructure integration promoted by the ministry of Land, Transport and Tourism of Japan.
● Optimized for OBUs (On-Board-Unit) that are ARIB STD-T75 compliant
The AK1553/AK1553E has the sufficient performance for OBUs that satisfy ARIB STD-T75 standard characteristics.
● Integrated Power Amplifier (PA) and Low Noise Amplifier (LNA)
The AK1553/AK1553E integrates a +14dBm output amplifier and an amplifier with -70dBm receiving sensitivity therefore external PA and LNA are not required in the system. Both transmission output power and receiving sensitivity can be adjusted, realizing to support various devices.
● Connectable to A Base-band LSI via Digital Interface
The AK1553/AK1553E can be connected with a baseband LSI via digital interface. Integrated ASK/QPSK modem of the AK1553/AK1553E eliminates modulation and demodulation processes in the baseband LSI so that an easy evaluation for system performance is available.
