GENERAL DESCRIPTION
nRF0433 is a true single chip UHF transceiver designed to operate in the 433MHz
ISM (Industrial, Scientific and Medical) frequency band. It features Frequency Shift
Keying (FSK) modulation and demodulation capability. nRF0433 operates at bit rates
up to 9600 bit/s. Transmit power can be adjusted to a maximum of 10dBm. It features
a differential antenna interface and an internal transmit/receive switch. nRF0433
operates from a single +5V DC supply.
As a primary application, nRF0433 is intended for design of UHF transceivers in
compliance with the European Telecommunication Standard Institute (ETSI)
specification EN 300 220-1 V1.2.1.

IMPORTANT TIMING DATA
Power up time
The time from power is switched on until the synthesised frequency is stable is the
power up time, ton. ton is 75 ms for nRF0433. Power up time can be reduced if a stable
4MHz reference signal (eg. from the driver pin of an active micro-controller) is
available at the XC1 input when powering up the transceiver. In this case ton is 7.5 ms.
Figure 4 shows a circuit diagram of a typical application. Note that these times may
vary depending on the crystal used.

Power up in transmit-mode
To avoid spurious emission outside the ISM-band during power-up of nRF0433, the
TXEN-input must be kept low until the synthesised frequency is stable (ton),
see figure 5.
When enabling transmit-mode, no data should be transmitted before the TXEN-input
has been high for at least 3ms (tdata-ton).
