Description
The MLX90109 is a single chip inductive RFID
transmitter-receiver for the 125kHz range. It has
been conceived for minimum system cost, and
minimum power consumption, whilst offering all
required flexibility for a state of the art AM Read-
Write base station.
An external L and C are connected as a parallel
resonant circuit, which will determine the carrier
frequency and the oscillator frequency of the
reader. This eliminates zero modulation effects,
and avoids the need for an external oscillator.
The antenna amplitude can be adjusted
externally on the fly. This allows straightforward
modulation of the antenna amplitude to write to
the transponder.
The reader IC can easily be switched to power
down by switching the antenna amplitude to
zero.
The MLX90109 can be configured to decode the
transponder signal on-chip. In this case the
decoded signal is available through a 2-wire
interface of clock and data. For minimum
interface wiring, the undecoded transponder
signal can also be made available on a single
wire interface.
