Description
Signal output from CMOS inverter-3 amplifier; this pin is connected to the
internal FSK signal digital demodulator.
Signal input to CMOS inverter-3 amplifier; if an external circuit is used to
amplify FSK signals, the amplified signals are input through this pin.
Signal output from CMOS inverter-2 amplifier.
Signal input to CMOS inverter-2 amplifier.
Signal output from CMOS inverter-1 amplifier.
I 16. Signal input to CMOS inverter-1 amplifier.
Negative level output of transmission signals; this output drives the
n-channel MOSFET used as antenna driver.
Positive level output of transmission signals; this output drives the
p-channel MOSFET used as antenna driver.
Signal input to 17.1776 MHz master clock oscillator.
Signal output from 17.1776 MHz master clock oscillator.
Negative power supply.
Positive power supply.
Input of transmission power selection signals (High-Low). A Low level
signal input through this pin substantially lowers the power during
transmission.
Input of transmission output control signals (Transmit-Receive Mode
Selector). A Low level signal input through this pin outputs a transmission
signal to either “TXLO/TXHI” pin while a High level signal input turns the
mode to Receive and activates the internal FSK signal digital demodulator.
Serial output of demodulated FSK signal bit data. Negative level output
when the bit data received from the remote transponder is “1”, and positive
level output when it is “0”.
Note:
The RI-RFM-006A has a reverse polarity in relation to
TIRIS
standard RF-modules.
Synchronous clock output of demodulated FSK signal data; a clock signal
synchronized with the “RXDT-“ signal is output.
