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).
