A low power UHF ASK/FSK transparent receiver device in a small QFN24 package. The transmitting frequency range is 433MHz to 435MHz band. The device combines the functions of remote keyless entry (RKE), a low bit rate ASK and tire pressure monitoring (TPM), a high bit rate FSK, into one receiver controled by an external microcontroller, such as an AVR® ATmega48. Works with PLL ATA5756 and ATA5757 transmitters. It supports Manchester bit rates of 1-10Kbits/s in ASK and 1-20Kbits/s in FSK mode with four selectable, discrete bit rate passbands. The receiver contains an RSSI output to indicate received signal strength and a SENSE input to select thresholds below which the DATA signal is gated off.
