Power Management
When the battery voltage falls below the shutdown voltage threshold (V SDWN ) the entire circuit switches off. After this
shutdown, the circuit is latched until a low level is applied on pin ENABLE (see State 4 of the state machine).

Data Clock
At start-up, data clock timing is valid after the data clock settling time. Because the clock is switched off asynchronously, the
last period duration cannot be guaranteed.

Electrical Characteristics
Unless otherwise specified, voltage range V cc =[V shutdown ;3.6 V], temperature range TA=[–40 °C;+ 125 °C], R ext =12 k Ω ± 5%,
RF output frequency f carrier = 433.92 MHz, reference frequency f reference = 13.560 MHz, output load RL = 50 Ω ± 1%
( Figure 9 ). Values refer to the circuit shown in the recommended application schematics: Figure 12 shows OOK modulation
and Figure 14 shows FSK modulation. Typical values reflect average measurement at VCC =3 V, TA = 25 ° C.
