DIMENSIONS / PIN ASSIGNMENTS

N.B.:

- The signals SLE, SCK and SDATA correspond to the 3-wire serial interface for

programming the transceiver registers.

- The radio module is supplied by an external power source between VDC and GND. The

supply voltage should be chosen in the 3-5V range.

The transmitter and receiver have to be configured (frequency registers, control registers...) to

establish the radio link. This register configuration is performed by means of the SLE, SCK

and SDATA 3-wire serial bus.

The number of registers to be programmed depends on the operating mode: transmission,

receipt... Each word is programmed starting with the most significant bit (MSB) and each bit

is loaded on the rising front of SCK.

N.B:

- In transmission mode (Tx) and receipt mode (Rx), the programming is different for any one

channel.

- The transmitter and receiver have to work on the same channel to "understand" each other.

- For this programming, it is understood that low level corresponds to GND and high level to

VDC.
