MAX7032 ASK/FSK Transceiver

Low-cost, crystal-based, programmable ASK/FSK transceiver with fractional-N PLL

Image of Maxim Integrated's MAX7032 ASK/FSK TransceiverMaxim's MAX7032 crystal-based, fractional-N transceiver is designed to transmit and receive ASK/OOK or FSK data in the 300 MHz to 450 MHz frequency range, with data rates up to 33 kbps (Manchester encoded) or 66 kbps (NRZ encoded). This device generates a typical output power of +10 dBm into a 50 Ω load, and exhibits typical sensitivities of -114 dBm for ASK data and -110 dBm for FSK data. The MAX7032 features separate transmit and receive pins (PAOUT and LNAIN) and provides an internal RF switch that can be used to connect the transmit and receive pins to a common antenna. The MAX7032 transmit frequency is generated by a 16-bit, fractional-N, phase-locked loop (PLL), while the receiver's local oscillator (LO) is generated by an integer-N PLL.
