ating frequency ranges, which has been specifically developed for the demands of RF
low-cost data transmission systems with data rates up to 32kBit/s using ASK or FSK modula-
tion. Its primary applications are in the application of Remote Keyless-Entry (RKE), Passive
Entry Go (PEG) System and Remote Start. The ATA5771 is designed for 868MHz application,
whereas ATA5773 for 315MHZ application and ATA5774 for 434MHz application.
