Low-Cost, 315MHz and 433.92MHz
ASK Transceiver with Fractional-N PLL
General Description
The MAX7030 crystal-based, fractional-N transceiver is
designed to transmit and receive ASK/OOK data at fac-
tory-preset carrier frequencies of 315MHz or
433.92MHz with data rates up to 33kbps (Manchester
encoded) or 66kbps (NRZ encoded). This device gen-
erates a typical output power of +10dBm into a 50 Ω
load and exhibits typical sensitivity of -114dBm. The
MAX7030 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 MAX7030 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 inte-
ger-N PLL. This hybrid architecture eliminates the need
for separate transmit and receive crystal reference
oscillators because the fractional-N PLL is preset to be
10.7MHz above the receive LO. Retaining the fixed-N
PLL for the receiver avoids the higher current-drain
requirements of a fractional-N PLL and keeps the
receiver current drain as low as possible. All frequency-
generation components are integrated on-chip, and
only a crystal, a 10.7MHz IF filter, and a few discrete
components are required to implement a complete
antenna/digital data solution.
The MAX7030 is available in a small, 5mm x 5mm, 32-
pin thin QFN package, and is specified to operate over
the automotive -40°C to +125°C temperature range.
