A7202A is a very easy-to-use CMOS RF Receiver for sub 1GHz license free ISM band (315/434MHz). It is an OOK/ASK single chip RF receiver with high sensitivity receiver (-110dBm @ 2.4Kbps, 315/433.92MHz). This device integrates a double balanced image reject mixer, low IF frequency (424KHz) architecture, IF filter, I/Q limiter with RSSI generation, as well as a fully VCO and PLL synthesizer. A7202A's carrier frequency FRF is determined by the frequency of the reference crystal FXTAL. The integer-N PLL synthesizer ensures that each RF value, ranging from 310 MHz to 315.5 MHz and 430 MHz to 438 MHz with PLL steps of 848KHz, can be achieved. This is done by using a crystal as a reference frequency according to: FRF = FXTAL x N / 32, where N is the PLL feedback divider ratio (N=743 for 315MHz band and N=1023 for 434MHz band, i.e. crystal = 13.5732MHz for 433.92MHz). Dut to AIF (Auto IF) function, user has no need to consider IF offset between TX and RX, but, just use this formula ( FRF = FXTAL x N / 32 ) directly to calculate RX radio frequency.\n\n\n\nFor easy-to-use, A7202A has a special mode called HW control mode. In HW control mode, user just needs to apply pin setting for radio control, i.e. Band =1 for 434MHz and Band = 0 for 315MHz. DF1, DF2, DF3 (data filter pins) and DS (data slicer pin) applying proper capacitors for different data rate application (1K to 10Kbps) to get the best RX sensitivity. Hence, A7202A is very easy to use with a low cost MCU or decoder. Those features are all integrated in a small SSOP 20 pins package.\n\n\n\nFor packet receiving, there is no RX FIFO inside A7202A. MCU (or Decoder) just needs to decode the coming packet (preamble + sync word + payload) from DATA_OUT pin. To get the best RX sensitivity, refer to section 9.6 for recommended preamble format to be 70% high and 30% low for this device.\n\n

A7205 is a high performance and low cost 2.4GHz ISM band wireless receiver. This device integrates high sensitivity receiver (- 95dBm @ 500Kbps). In low data rate application, A7205 has special strength for long LOS (line-of-sight) distance because of its ultra high sensitivity (-107 dBm @ 2Kbps, - 104 dBm @ 25Kbps) with no requirement of external LNA. Based on Data Rate Register (0x0E), user can configure on-air data rates from 2Kbps to 500Kbps.\n\n\n\nA7205 supports fast settling time (130 us) for frequency hopping system. For packet handling, A7205 has a built-in 64-bytes RX FIFO (could be extended to 256 bytes) for data buffering and burst transmission, CRC for error detection, RSSI for clear channel assessment, data whitening for data decryption. Those functions are very easy to use while developing a wireless system. All features are integrated in a small QFN 4X4 20 pins package.\n\n\n\nA7205’s control registers can be easily accessed via 3-wire or 4-wire SPI. For power saving, A7205 supports sleep mode, idle mode, standby mode. For easy-to-use, A7205 has an unique SPI command set called Strobe command that are used to control internal state machine. Based on Strobe commands, MCU can control everything from power saving, RX receiving,channel monitoring, frequency hopping to auto calibrations. In addition, A7205 supports two general purpose I/O pins, GIO1 and GIO2, to inform MCU its status so that MCU could use either polling or interrupt scheme to do radio control. Hence, it is very easy to monitor radio transmission between MCU and A7205 because of its digital interface.
