PRODUCTION DATA
The device is supplied with 5 V by an external voltage regulator through two supply pins, one for providing the driver current for the antenna and the analog part in front of the digital demodulator and one for supplying the other blocks.
The power supply supplies a power-on reset that brings the control logic into Idle state as soon as the supply voltage drops under a certain value.
In Sleep state, the sum of both supply currents is reduced to 0.2 mA. The base station device falls into Sleep state 100 ms after TXCT has changed to high. When TXCT changes to low or is low, the base station IC immediately goes into and remains in normal operation.
