Single chip 433MHz RF Transceiver
FEATURES
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.

... Power up time The time from power is switched on until the synthesised frequency is stable is the power up time for nRF0433. Power up time can be reduced if a stable on on 4MHz reference signal (eg. from the driver pin of an active micro-controller) is available at the XC1 input when powering up the transceiver.

... A well-designed PCB is necessary to achieve good RF performance. A PCB with a minimum of two layers inclusive a ground plane is recommended for optimum performance. The nRF0433 +5V DC supply voltage should be decoupled as close as possible to the VDD pins with a high performance RF capacitor (e.g. 100 pF ceramic preferable to mount a large surface mount capacitor (e.g. 2.2 F ceramic) in parallel with the smaller value capacitors ...
