1.2 General Description
The UHF ASK/FSK Fractional-N Transmitter IC (FraNTIC)
is intended for future integration with the NXP MRKII micro-
controller. For this purpose, FRANTIC is implemented in
sophisticated SI CMOS technology. The device provides a
fully integrated fractional-N phase locked loop (PLL)
frequency synthesizer and a power amplifier to drive an
external antenna.
FRANTIC is especially designed for use in the ISM
frequency bands (315/434/868/915 MHz). Fine-tuning of
the reference oscillator by means of fractional-N synthesis
allows the compensation of manufacturing tolerances of the
crystal. The device also includes an adjustable output
power capability.
FRANTIC can be used for both ASK and FSK modulation
with data rates up to 40 kBit/s. Due to the high level of
integration, only few external components are needed to
build up a complete transmitter.
