Low-Cost, Crystal-Based, Programmable,

ASK/FSK Transceiver with Fractional-N PLL

General Description

Features

The MAX7032 crystal-based, fractional-N transceiver is

designed to transmit and receive ASK/OOK or FSK

data in the 300MHz to 450MHz frequency range with

data rates up to 33kbps (Manchester encoded) or

66kbps (NRZ encoded). This device generates a typi-

cal output power of +10dBm into a 50Ω load, and

exhibits typical sensitivities of -114dBm for ASK data

and -110dBm for FSK data. The MAX7032 features sep-

arate 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

♦ User-Adjustable 300MHz to 450MHz Carrier

Frequency

♦ ASK/OOK and FSK Modulation

♦ User-Adjustable FSK Frequency Deviation

Through Fractional-N PLL Register

♦ Agile Transmitter Frequency Synthesizer with

/ 4096 Carrier-Frequency Spacing

XTAL

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 inte-

ger-N PLL. This hybrid architecture eliminates the need

for separate transmit and receive crystal reference

oscillators because the fractional-N PLL allows the

transmit frequency to be set within 2kHz of the receive

frequency. The 12-bit resolution of the fractional-N PLL

allows frequency multiplication of the crystal frequency

♦ +10dBm Output Power into 50Ω Load

♦ Integrated TX/RX Switch

♦ Integrated Transmit and Receive PLL, VCO, and

Loop Filter

♦ > 45dB Image Rejection

♦ Typical RF Sensitivity*

ASK: -114dBm

in steps of f

/ 4096. Retaining the fixed-N PLL for

XTAL

the receiver avoids the higher current drain require-

ments of a fractional-N PLL and keeps the receiver cur-

rent drain as low as possible.

FSK: -110dBm

♦ Selectable IF Bandwidth with External Filter

♦ RSSI Output with High Dynamic Range

♦ Autopolling Low-Power Management

♦ < 12.5mA Transmit-Mode Current

♦ < 6.7mA Receive-Mode Current

♦ < 23.5µA Polling-Mode Current

The fractional-N architecture of the MAX7032 transmit

PLL allows the transmit FSK signal to be programmed 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 imple-

ment a complete antenna/digital data solution.

♦ < 800nA Shutdown Current

The MAX7032 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.

♦ Fast-On Startup Feature, < 250µs

♦ Small 32-Pin, Thin QFN Package
