The MAX7060 frequency and power-programmable
ASK/FSK transmitter operates at 280MHz to 450MHz
frequencies. This device incorporates a fully integrated
fractional-N synthesizer, which allows the user to set the
RF operating frequency to a large fraction of the 280MHz
to 450MHz frequency range with a single crystal. For
example, the MAX7060 can be tuned from 285MHz to
420MHz with a 15MHz crystal. The RF output power is
user-controlled between +14dBm and -14dBm, with a
5V supply or with battery voltages as low as 3.2V. At the
minimum specified battery voltage of 2.1V, the RF output
power-control range is between +10dBm and -14dBm.
To maintain a good output power match across a broad
range of frequencies, the MAX7060 also contains a pro-
grammable matching capacitor connected in parallel
with the power amplifier (PA) output.
ASK modulation is accomplished by switching the PA
on and off, so excellent modulation (on/off) ratios are
achieved. ASK amplitude shaping is available to reduce
the width of the transmission spectrum. FSK modula-
tion is accomplished by changing the coefficients of
the high-resolution fractional-N synthesizer, so FSK
deviation is extremely accurate. Data rates up to 50kbps
Manchester coded for ASK and 70kbps Manchester
coded for FSK can be maintained while still satisfying
regulatory emission-bandwidth standards. The full set of
configuration functions are handled by an on-chip serial
peripheral interface (SPIK). There is also a manual mode
where a limited number of settings can be made directly
through selected pins.
The startup time is very short, and data can be transmit-
ted 250Fs after the enable command. The MAX7060
operates from a 2.1V to 3.6V supply, or internal regula-
tors can be used for supply voltages between 4.5V and
5.5V. The standby current in the 3V mode is 400nA at
room temperature, and can be reduced to 5nA using the
low-power shutdown (LSHDN) pin.
The MAX7060 is available in a 24-pin (4mm x 4mm) thin
QFN package and is specified for the automotive tem-
perature range from -40NC to +125NC.
