RKE TRANSCEIVER
MANUAL
FCC : 2AS9T-ASRKET01
ISED : 27298-ASRKET01
KC : R-C-Amo-ASRKET01
Description
Features
The RKE RF Transceiver acts as a control unit that transmits and receives RF signals sent
from a vehicle key or smart key. After demodulating the received RF signal and
performing digital signal processing, it interfaces with in-vehicle controllers to perform
vehicle access control functions such as remote door lock/unlock, trunk opening/closing,
and remote start

How to install
Recommaned mounting location is headliner.
And position can be determined by evaluation result or sensitivity level(reception rate)
- Set RKE and vehicle direction to 16 directions
(22.5-degree intervals), numbering from 1 to 16.
-Measure maximum reception distance (m) per
direction
-> A reception distance of at least 30 (m) must
be obtained.

Functional Description
The RKE Transceiver receives RF signals transmitted from the vehicle key FOB through an
antenna. The received signal passes through a SAW filter and is then delivered to the
RFIC (ATA5833). The RFIC demodulates the received RF signal using its internal Low-IF
and digital DSP architecture, and transfers the demodulated data to the MCU (S32K312).
The MCU verifies the received data and transmits it to the vehicle CAN network through
the CAN Transceiver (TCAN1463), enabling communication with the BDC.
During transmission, under MCU control, the RFIC outputs an RF transmission signal to
the antenna, enabling two-way communication with the FOB or transmission of response
signals. The RF transmit and receive paths are selectively switched through a switch.
Power is supplied from the vehicle power source and converted to 5 V through an LDO
(TPS7B8650). The 5 V power is then supplied to the RFIC, MCU, CAN Transceiver, and
peripheral circuits. The unit is connected to the vehicle Local-CAN network through the
CANH/CANL lines and transmits the received RKE-related RF data.
FCC Compliance Statement
This device complies with part 15 of the FCC rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.
FCC Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to correct the interference by one of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
FCC Caution
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment. This transmitter
must not be co-located or operating in conjunction with any other antenna or
transmitter.
FCC Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance
20 cm between the radiator and your body. This transmitter must not be co-located or
operating in conjunction with any other antenna or transmitter.
Industry Canada Statement
This device complies with RSS-210 of the Industry Canada Rules. Operation is subject to
the following two conditions: (1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may cause
undesired operation. Ce dispositif est conforme à la norme CNR-210 d’Industrie Canada
applicable aux appareils radio exempts de licence. Son fonctionnement est sujet aux
deux conditions suivantes: (1) le dispositif ne doit pas produire de brouillage
préjudiciable, et (2) ce dispositif doit accepter tout brouillage reçu, y compris un
brouillage susceptible de provoquer un fonctionnement indésirable.
Industry Canada Radiation Exposure Statement
This equipment complies with IC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance
20 cm between the radiator & your body.
Déclaration d’exposition aux radiations
