ATA8202 is used in the 433 MHz to 435 MHz band of operation, and ATA8201 in 313 MHz to 317 MHz. For improved image rejection and selectivity, the IF frequency is fixed to 440 kHz. The IF block uses an 8th-order band pass yielding a receive bandwidth of 420 kHz. This enables the use of the receiver in both SAW- and PLL-based transmitter systems utilizing various types of data-bit encoding such as pulse width modulation, Manchester modulation, variable pulse modulation, pulse position modulation, and NRZ. Prevailing encryption protocols such as are easily supported due to the receiver’s ability to hold the current data slicer threshold for up to 52 ms when incoming RF telegrams contain a blanking interval. This feature eliminates erroneous noise from appearing on the demodulated data output pin, and simplifies software decoding algorithms. The decoding of the data stream must be carried out by a connected microcontroller device. Because of the highly integrated design, the only required RF components are for the purpose of receiver antenna matching. ATA8201 and ATA8202 support Manchester bit rates of 1 Kbit/s to 10 Kbits/s in ASK and 1 Kbit/s to 20 Kbits/s in FSK mode. The four discrete bit rate passbands are selectable and cover Kbit/s to Kbits/s, Kbits/s to Kbits/s, Kbits/s to Kbits/s, and Kbits/s to Kbits/s or Kbits/s for ASK or FSK, respectively . The receiver contains an RSSI output to provide an indication of received signal strength and a SENSE input to allow the customer to select a threshold below which the DATA signal is gated off. ASK/FSK and bit rate ranges are selected by the connected microcontroller device via pins ASK_NFSK, BR0, and BR1.
