19-3707; Rev 0; 5/05

Low-Cost, 308MHz, 315MHz, and 433.92MHz

FSK Transceiver with Fractional-N PLL

General Description

Features

The MAX7031 crystal-based, fractional-N transceiver is

designed to transmit and receive FSK data at factory-

preset carrier frequencies of 308MHz^†, 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 50Ω

load, and exhibits typical sensitivity of -110dBm. The

MAX7031 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.

♦ +2.1V to +3.6V or +4.5V to +5.5V Single-Supply

Operation

♦ Single-Crystal Transceiver

♦ Factory-Preset Frequency (No Serial Interface

Required)

♦ FSK Modulation

♦ Factory-Preset FSK Frequency Deviation

♦ +10dBm Output Power into 50Ω Load

♦ Integrated TX/RX Switch

The MAX7031 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.

♦ Integrated Transmit and Receive PLL, VCO, and

Loop Filter

♦ > 45dB Image Rejection

♦ Typical RF Sensitivity*: -110dBm

♦ Selectable IF Bandwidth with External Filter

♦ RSSI Output with High Dynamic Range

♦ < 12.5mA Transmit-Mode Current

♦ < 6.7mA Receive-Mode Current

♦ < 800nA Shutdown Current

The fractional-N architecture of the MAX7031 transmit

PLL allows the transmit FSK signal to be preset for

exact frequency deviations, and completely eliminates

the problems associated with oscillator-pulling FSK sig-

nal generation. 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.

♦ Fast-On Startup Feature, < 250µs

♦ Small, 32-Pin, Thin QFN Package

*0.2% BER, 4kbps Manchester-encoded data, 280kHz IF BW

The MAX7031 is available in a small, 5mm x 5mm, 32-

pin, thin QFN package, and is specified to operate in

the automotive -40°C to +125°C temperature range.
