ESCRIPTION

FC3810 is a complete RF to baseband ASK

(amplitude shift keying) transceiver IC of FCI’s netRF™

family for worldwide ETCS (electronic toll collection

system) applications. FC3810 is a true single chip for

5.8GHz band ETC application since it integrates all the

required receiver, transmitter, VCO, and PLL enabling

tiny low power ETC RF solution.

The receiver part receives 5.8GHz band ASK

modulated RF signal from the antenna and gives

demodulated baseband ASK DATA to the ASK modem

chip. The receiver part is comprised of LNA, down-

converter, channel select filter, and ASK demodulator.

The transmitter part receives digital data from the ASK

modem chip and transmit 5.8GHz band ASK modulated

RF signal to the antenna. The transmit part contains

data up-converter and drive amplifier. FC3810

integrates the entire required PLL block such as VCO,

fractional-N synthesizer, crystal oscillator for LO signal

generation for receiving and transmitting. Two wired

serial programmable interface protocol enables

FC3810 to operate in various modes.

For ASK 5.8GHz band ETC system, external

components such as IF SAW filter, and IF ASK

demodulator are no longer required because of

FC3810 fully integrated ASK transceiver IC. FC3810 is

available in a 6mm x 6mm 40-pin MLF package.
