The transmitter and receiver blocks are not enabled in this state. The chip temperature is measured using the ADC, which can be read from Register adc_rbk, Field adc_out, and is continuously updated with the chip temperature reading. This state is enabled by issuing the RC_MEAS command from...
If transmitter and receiver are in different branches of the circuit, separated for example by a service panel, there is an additional attenuation of 10-20 dB. In some worst-case conditions (socket with very low impedance) the attenuation of the transmitted signal can reach a value of 50-60...
transmitter and receiver • Separate signal polarity control for transmission and reception • Swappable Tx/Rx pin configuration • Hardware flow control for modem and RS-485 transceiver • Communication control/error detection flags • Parity control: – Transmits parity bit – Checks parity ...
Figure 14. Recommended Crystal Connection to the IC The crystal initial tolerance, temperature coefficient, and aging must be specified so that the cumulative error between the transmitter and companion receiver frequencies allows proper operation. The transmitted signal must be downconverted by the ...

Transmitter simulations The goal of this simulation is to determine the Binary FSK arctangent-differentiated demodulator Low power, direct-conversion architecture and the frequency hopping features of our receiver architecture constrain the choice of the FSK detector. Simple flip–flop detectors or zero-...
Multichannel ISM Band FSK/GFSK/OOK/GOOK/ASK Transmitter ADF7012 FEATURES GENERAL DESCRIPTION Single-chip, low power UHF transmitter The ADF7012 is a low power FSK/GFSK/OOK/GOOK/ASK 75 MHz to 1 GHz frequency operation UHF transmitter designed for short-range devices (SRDs). The Multichannel ...
FIGS. 5(a) and 5(b) are block diagrams illustrating a conventional transmitter/receiver for two-value-to-four-value conversion; and FIG. 5(c) is a waveform diagram showing a code signal on a four-valued frequency/amplitude plane. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A multivalued...
provides a common reference between the transmitter and receiver. With the present invention, therefore, expensive precision components are not required since all critical frequencies are derived from the power line carrier frequency in both the receiver and transmitter. In addition, synchronous detection...
