1. General information

This Korean RF Receiver is used for RKE functions on vehicles.
The receiver principle is super heterodyne PLL frequency synthesizer and designed
for the reception of 1KHz Manchester codes with only FSK signal optimized.
The Center frequency are 433.92MHz(5WY8231, NA).
This receiver has oriented enhanced RF LNA characteristic to improve RF sensitivity
instead of internal LNA part of InfineonTDA 522x provided.(removed internal LNA)
The receiver module is best optimized SAW filter, External LNA and 1K data baud
filtering for data band spectrum noise characteristic.
This receiver has 9 leg’s(1.Antenna input, 2.GND- antenna, 3.LNA- power supply,

4.Vcc-power supply, 5.PWDN, 6.RSSI, 7.DATA-output, 8.GND, 9.MSL)

which will be united to SRX PCB by wave soldering.( stick into main PCB by hand).

4.1 Sensitivity Variation over temperature

Sensitivity Variation T=-40 to 85°C: normal sense @ RM ≤ ±3dB

4.2 FSK frequency-deviation

Max .FSK deviation F= ±120 kHz

Min. FSK deviation 1k variants F = ± 10 kHz

For the min. sensitivity, under the degraded Freq-deviation less than 30 KHz, could be allowed within 3dB.

5. Current Consumption; Vcc = 5 V (RT)

(no RF – signal applied to the receiver input)

 No RF signal applied at RF input

5.2 Active current (Switching High) with LNA

@ T=25ºC (RT):

FSK I

8.4 Homologation statement

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

interferencethat may cause undesired operation.

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 try to correct the
interference by one or more 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 that to which the

receiver is connected.

- Consult the dealer or an experienced radio/TV technician for help.

Do Not

Any changes or modifications to the equipment not expressly
approved by the party responsible for compliance could void

user’s authority to operate the equipment.
