Continental Automotive I BS PG3 WL Page 2 of 6 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). 1.Operating temperature range -40 ºC < T < +85 ºC 2. Technical Data All data is specified at T= 25 °C (RT) and VCC = 5V 3. VCO – Frequency Frequency Variants VCO frequency Tolerance T=-40 ºC to +85 ºC 433.92MHz, 846.44MHz ± 90ppm 4. Input Sensitivity Input sensitivity at center frequency, BER 10 -2 (Vcc=5V)  FSK: fmod = 1 kHz square- wave +/-35KHz deviation. Variants Description Condition Typ min unit 5WY 8231 433.92MHz, FSK,1K FSK ,Fmod=1KHz -110 ≤ -107 dBm

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) 5.1 Current consumption  Vcc = 5 V,  No RF signal applied at RF input 5.2 Active current (Switching High) with LNA @ T=25ºC (RT): FSK Is < 9.1 mA @T=-40 to +85°C FSK Is < 9.3 mA 5.3 Standby current (switching Low) with LNA @ T=-40 to +85°C Is < 5 µA The power supply is not ESD protected. This protection must be done on the main board (ECU). Sensitivity Variation T=-40 to 85°C: normal sense @ RM ≤ ±3dB

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.
