... Powerdown register settings. When the PWDN pin is high, power management is under control of the Powerdown register L bits. MATCH The IF and RF sections of the Si2200 circuitry can individually powered down by setting the Powerdown 27 nH register bits, PDIB and PDRB, low. The reference 18 nH frequency amplifier will also be powered up if either the PDRB or PDIB bits are high ...
