Reset Circuit for I
If the design uses the I
ISEL/RST pin to achieve the correct T
easiest way to provide the reset is to connect a GPIO pin from the microcontroller to the transmitter chip as
shown in Figure 13. The reset pulse can then be commanded either at power-up time or just prior to initial use of
the I
Power Control
The low-power standby state feature of the chip provides a design option of leaving the chip always powered, as
opposed to powering it on and off. Leaving the chip powered and using the PD pin to put it in a lower power state
may result in faster system response time, depending on the system Vcc supply ramp-up delay.
Table 9 provides information on chip functional mode current requirements. These values are not specifications,
but are representative of typical chip power consumption. PVCC1 and PVCC2 are the power planes that are
most sensitive to excessive noise. Noise on these planes can be more easily controlled when they are regulated
separately from digital VCC.
